+
+ Frequently Asked Questions about zlib
+
+
+If your question is not there, please check the zlib home page
+http://zlib.net/ which may have more recent information.
+The lastest zlib FAQ is at http://zlib.net/zlib_faq.html
+
+
+ 1. Is zlib Y2K-compliant?
+
+ Yes. zlib doesn't handle dates.
+
+ 2. Where can I get a Windows DLL version?
+
+ The zlib sources can be compiled without change to produce a DLL. See the
+ file win32/DLL_FAQ.txt in the zlib distribution. Pointers to the
+ precompiled DLL are found in the zlib web site at http://zlib.net/ .
+
+ 3. Where can I get a Visual Basic interface to zlib?
+
+ See
+ * http://marknelson.us/1997/01/01/zlib-engine/
+ * win32/DLL_FAQ.txt in the zlib distribution
+
+ 4. compress() returns Z_BUF_ERROR.
+
+ Make sure that before the call of compress(), the length of the compressed
+ buffer is equal to the available size of the compressed buffer and not
+ zero. For Visual Basic, check that this parameter is passed by reference
+ ("as any"), not by value ("as long").
+
+ 5. deflate() or inflate() returns Z_BUF_ERROR.
+
+ Before making the call, make sure that avail_in and avail_out are not zero.
+ When setting the parameter flush equal to Z_FINISH, also make sure that
+ avail_out is big enough to allow processing all pending input. Note that a
+ Z_BUF_ERROR is not fatal--another call to deflate() or inflate() can be
+ made with more input or output space. A Z_BUF_ERROR may in fact be
+ unavoidable depending on how the functions are used, since it is not
+ possible to tell whether or not there is more output pending when
+ strm.avail_out returns with zero. See http://zlib.net/zlib_how.html for a
+ heavily annotated example.
+
+ 6. Where's the zlib documentation (man pages, etc.)?
+
+ It's in zlib.h . Examples of zlib usage are in the files test/example.c
+ and test/minigzip.c, with more in examples/ .
+
+ 7. Why don't you use GNU autoconf or libtool or ...?
+
+ Because we would like to keep zlib as a very small and simple package.
+ zlib is rather portable and doesn't need much configuration.
+
+ 8. I found a bug in zlib.
+
+ Most of the time, such problems are due to an incorrect usage of zlib.
+ Please try to reproduce the problem with a small program and send the
+ corresponding source to us at zlib@gzip.org . Do not send multi-megabyte
+ data files without prior agreement.
+
+ 9. Why do I get "undefined reference to gzputc"?
+
+ If "make test" produces something like
+
+ example.o(.text+0x154): undefined reference to `gzputc'
+
+ check that you don't have old files libz.* in /usr/lib, /usr/local/lib or
+ /usr/X11R6/lib. Remove any old versions, then do "make install".
+
+10. I need a Delphi interface to zlib.
+
+ See the contrib/delphi directory in the zlib distribution.
+
+11. Can zlib handle .zip archives?
+
+ Not by itself, no. See the directory contrib/minizip in the zlib
+ distribution.
+
+12. Can zlib handle .Z files?
+
+ No, sorry. You have to spawn an uncompress or gunzip subprocess, or adapt
+ the code of uncompress on your own.
+
+13. How can I make a Unix shared library?
+
+ By default a shared (and a static) library is built for Unix. So:
+
+ make distclean
+ ./configure
+ make
+
+14. How do I install a shared zlib library on Unix?
+
+ After the above, then:
+
+ make install
+
+ However, many flavors of Unix come with a shared zlib already installed.
+ Before going to the trouble of compiling a shared version of zlib and
+ trying to install it, you may want to check if it's already there! If you
+ can #include <zlib.h>, it's there. The -lz option will probably link to
+ it. You can check the version at the top of zlib.h or with the
+ ZLIB_VERSION symbol defined in zlib.h .
+
+15. I have a question about OttoPDF.
+
+ We are not the authors of OttoPDF. The real author is on the OttoPDF web
+ site: Joel Hainley, jhainley@myndkryme.com.
+
+16. Can zlib decode Flate data in an Adobe PDF file?
+
+ Yes. See http://www.pdflib.com/ . To modify PDF forms, see
+ http://sourceforge.net/projects/acroformtool/ .
+
+17. Why am I getting this "register_frame_info not found" error on Solaris?
+
+ After installing zlib 1.1.4 on Solaris 2.6, running applications using zlib
+ generates an error such as:
+
+ ld.so.1: rpm: fatal: relocation error: file /usr/local/lib/libz.so:
+ symbol __register_frame_info: referenced symbol not found
+
+ The symbol __register_frame_info is not part of zlib, it is generated by
+ the C compiler (cc or gcc). You must recompile applications using zlib
+ which have this problem. This problem is specific to Solaris. See
+ http://www.sunfreeware.com for Solaris versions of zlib and applications
+ using zlib.
+
+18. Why does gzip give an error on a file I make with compress/deflate?
+
+ The compress and deflate functions produce data in the zlib format, which
+ is different and incompatible with the gzip format. The gz* functions in
+ zlib on the other hand use the gzip format. Both the zlib and gzip formats
+ use the same compressed data format internally, but have different headers
+ and trailers around the compressed data.
+
+19. Ok, so why are there two different formats?
+
+ The gzip format was designed to retain the directory information about a
+ single file, such as the name and last modification date. The zlib format
+ on the other hand was designed for in-memory and communication channel
+ applications, and has a much more compact header and trailer and uses a
+ faster integrity check than gzip.
+
+20. Well that's nice, but how do I make a gzip file in memory?
+
+ You can request that deflate write the gzip format instead of the zlib
+ format using deflateInit2(). You can also request that inflate decode the
+ gzip format using inflateInit2(). Read zlib.h for more details.
+
+21. Is zlib thread-safe?
+
+ Yes. However any library routines that zlib uses and any application-
+ provided memory allocation routines must also be thread-safe. zlib's gz*
+ functions use stdio library routines, and most of zlib's functions use the
+ library memory allocation routines by default. zlib's *Init* functions
+ allow for the application to provide custom memory allocation routines.
+
+ Of course, you should only operate on any given zlib or gzip stream from a
+ single thread at a time.
+
+22. Can I use zlib in my commercial application?
+
+ Yes. Please read the license in zlib.h.
+
+23. Is zlib under the GNU license?
+
+ No. Please read the license in zlib.h.
+
+24. The license says that altered source versions must be "plainly marked". So
+ what exactly do I need to do to meet that requirement?
+
+ You need to change the ZLIB_VERSION and ZLIB_VERNUM #defines in zlib.h. In
+ particular, the final version number needs to be changed to "f", and an
+ identification string should be appended to ZLIB_VERSION. Version numbers
+ x.x.x.f are reserved for modifications to zlib by others than the zlib
+ maintainers. For example, if the version of the base zlib you are altering
+ is "1.2.3.4", then in zlib.h you should change ZLIB_VERNUM to 0x123f, and
+ ZLIB_VERSION to something like "1.2.3.f-zachary-mods-v3". You can also
+ update the version strings in deflate.c and inftrees.c.
+
+ For altered source distributions, you should also note the origin and
+ nature of the changes in zlib.h, as well as in ChangeLog and README, along
+ with the dates of the alterations. The origin should include at least your
+ name (or your company's name), and an email address to contact for help or
+ issues with the library.
+
+ Note that distributing a compiled zlib library along with zlib.h and
+ zconf.h is also a source distribution, and so you should change
+ ZLIB_VERSION and ZLIB_VERNUM and note the origin and nature of the changes
+ in zlib.h as you would for a full source distribution.
+
+25. Will zlib work on a big-endian or little-endian architecture, and can I
+ exchange compressed data between them?
+
+ Yes and yes.
+
+26. Will zlib work on a 64-bit machine?
+
+ Yes. It has been tested on 64-bit machines, and has no dependence on any
+ data types being limited to 32-bits in length. If you have any
+ difficulties, please provide a complete problem report to zlib@gzip.org
+
+27. Will zlib decompress data from the PKWare Data Compression Library?
+
+ No. The PKWare DCL uses a completely different compressed data format than
+ does PKZIP and zlib. However, you can look in zlib's contrib/blast
+ directory for a possible solution to your problem.
+
+28. Can I access data randomly in a compressed stream?
+
+ No, not without some preparation. If when compressing you periodically use
+ Z_FULL_FLUSH, carefully write all the pending data at those points, and
+ keep an index of those locations, then you can start decompression at those
+ points. You have to be careful to not use Z_FULL_FLUSH too often, since it
+ can significantly degrade compression. Alternatively, you can scan a
+ deflate stream once to generate an index, and then use that index for
+ random access. See examples/zran.c .
+
+29. Does zlib work on MVS, OS/390, CICS, etc.?
+
+ It has in the past, but we have not heard of any recent evidence. There
+ were working ports of zlib 1.1.4 to MVS, but those links no longer work.
+ If you know of recent, successful applications of zlib on these operating
+ systems, please let us know. Thanks.
+
+30. Is there some simpler, easier to read version of inflate I can look at to
+ understand the deflate format?
+
+ First off, you should read RFC 1951. Second, yes. Look in zlib's
+ contrib/puff directory.
+
+31. Does zlib infringe on any patents?
+
+ As far as we know, no. In fact, that was originally the whole point behind
+ zlib. Look here for some more information:
+
+ http://www.gzip.org/#faq11
+
+32. Can zlib work with greater than 4 GB of data?
+
+ Yes. inflate() and deflate() will process any amount of data correctly.
+ Each call of inflate() or deflate() is limited to input and output chunks
+ of the maximum value that can be stored in the compiler's "unsigned int"
+ type, but there is no limit to the number of chunks. Note however that the
+ strm.total_in and strm_total_out counters may be limited to 4 GB. These
+ counters are provided as a convenience and are not used internally by
+ inflate() or deflate(). The application can easily set up its own counters
+ updated after each call of inflate() or deflate() to count beyond 4 GB.
+ compress() and uncompress() may be limited to 4 GB, since they operate in a
+ single call. gzseek() and gztell() may be limited to 4 GB depending on how
+ zlib is compiled. See the zlibCompileFlags() function in zlib.h.
+
+ The word "may" appears several times above since there is a 4 GB limit only
+ if the compiler's "long" type is 32 bits. If the compiler's "long" type is
+ 64 bits, then the limit is 16 exabytes.
+
+33. Does zlib have any security vulnerabilities?
+
+ The only one that we are aware of is potentially in gzprintf(). If zlib is
+ compiled to use sprintf() or vsprintf(), then there is no protection
+ against a buffer overflow of an 8K string space (or other value as set by
+ gzbuffer()), other than the caller of gzprintf() assuring that the output
+ will not exceed 8K. On the other hand, if zlib is compiled to use
+ snprintf() or vsnprintf(), which should normally be the case, then there is
+ no vulnerability. The ./configure script will display warnings if an
+ insecure variation of sprintf() will be used by gzprintf(). Also the
+ zlibCompileFlags() function will return information on what variant of
+ sprintf() is used by gzprintf().
+
+ If you don't have snprintf() or vsnprintf() and would like one, you can
+ find a portable implementation here:
+
+ http://www.ijs.si/software/snprintf/
+
+ Note that you should be using the most recent version of zlib. Versions
+ 1.1.3 and before were subject to a double-free vulnerability, and versions
+ 1.2.1 and 1.2.2 were subject to an access exception when decompressing
+ invalid compressed data.
+
+34. Is there a Java version of zlib?
+
+ Probably what you want is to use zlib in Java. zlib is already included
+ as part of the Java SDK in the java.util.zip package. If you really want
+ a version of zlib written in the Java language, look on the zlib home
+ page for links: http://zlib.net/ .
+
+35. I get this or that compiler or source-code scanner warning when I crank it
+ up to maximally-pedantic. Can't you guys write proper code?
+
+ Many years ago, we gave up attempting to avoid warnings on every compiler
+ in the universe. It just got to be a waste of time, and some compilers
+ were downright silly as well as contradicted each other. So now, we simply
+ make sure that the code always works.
+
+36. Valgrind (or some similar memory access checker) says that deflate is
+ performing a conditional jump that depends on an uninitialized value.
+ Isn't that a bug?
+
+ No. That is intentional for performance reasons, and the output of deflate
+ is not affected. This only started showing up recently since zlib 1.2.x
+ uses malloc() by default for allocations, whereas earlier versions used
+ calloc(), which zeros out the allocated memory. Even though the code was
+ correct, versions 1.2.4 and later was changed to not stimulate these
+ checkers.
+
+37. Will zlib read the (insert any ancient or arcane format here) compressed
+ data format?
+
+ Probably not. Look in the comp.compression FAQ for pointers to various
+ formats and associated software.
+
+38. How can I encrypt/decrypt zip files with zlib?
+
+ zlib doesn't support encryption. The original PKZIP encryption is very
+ weak and can be broken with freely available programs. To get strong
+ encryption, use GnuPG, http://www.gnupg.org/ , which already includes zlib
+ compression. For PKZIP compatible "encryption", look at
+ http://www.info-zip.org/
+
+39. What's the difference between the "gzip" and "deflate" HTTP 1.1 encodings?
+
+ "gzip" is the gzip format, and "deflate" is the zlib format. They should
+ probably have called the second one "zlib" instead to avoid confusion with
+ the raw deflate compressed data format. While the HTTP 1.1 RFC 2616
+ correctly points to the zlib specification in RFC 1950 for the "deflate"
+ transfer encoding, there have been reports of servers and browsers that
+ incorrectly produce or expect raw deflate data per the deflate
+ specification in RFC 1951, most notably Microsoft. So even though the
+ "deflate" transfer encoding using the zlib format would be the more
+ efficient approach (and in fact exactly what the zlib format was designed
+ for), using the "gzip" transfer encoding is probably more reliable due to
+ an unfortunate choice of name on the part of the HTTP 1.1 authors.
+
+ Bottom line: use the gzip format for HTTP 1.1 encoding.
+
+40. Does zlib support the new "Deflate64" format introduced by PKWare?
+
+ No. PKWare has apparently decided to keep that format proprietary, since
+ they have not documented it as they have previous compression formats. In
+ any case, the compression improvements are so modest compared to other more
+ modern approaches, that it's not worth the effort to implement.
+
+41. I'm having a problem with the zip functions in zlib, can you help?
+
+ There are no zip functions in zlib. You are probably using minizip by
+ Giles Vollant, which is found in the contrib directory of zlib. It is not
+ part of zlib. In fact none of the stuff in contrib is part of zlib. The
+ files in there are not supported by the zlib authors. You need to contact
+ the authors of the respective contribution for help.
+
+42. The match.asm code in contrib is under the GNU General Public License.
+ Since it's part of zlib, doesn't that mean that all of zlib falls under the
+ GNU GPL?
+
+ No. The files in contrib are not part of zlib. They were contributed by
+ other authors and are provided as a convenience to the user within the zlib
+ distribution. Each item in contrib has its own license.
+
+43. Is zlib subject to export controls? What is its ECCN?
+
+ zlib is not subject to export controls, and so is classified as EAR99.
+
+44. Can you please sign these lengthy legal documents and fax them back to us
+ so that we can use your software in our product?
+
+ No. Go away. Shoo.

+ZLIB DATA COMPRESSION LIBRARY
+
+zlib 1.2.6 is a general purpose data compression library. All the code is
+thread safe. The data format used by the zlib library is described by RFCs
+(Request for Comments) 1950 to 1952 in the files
+http://tools.ietf.org/html/rfc1950 (zlib format), rfc1951 (deflate format) and
+rfc1952 (gzip format).
+
+All functions of the compression library are documented in the file zlib.h
+(volunteer to write man pages welcome, contact zlib@gzip.org). A usage example
+of the library is given in the file test/example.c which also tests that
+the library is working correctly. Another example is given in the file
+test/minigzip.c. The compression library itself is composed of all source
+files in the root directory.
+
+To compile all files and run the test program, follow the instructions given at
+the top of Makefile.in. In short "./configure; make test", and if that goes
+well, "make install" should work for most flavors of Unix. For Windows, use
+one of the special makefiles in win32/ or contrib/vstudio/ . For VMS, use
+make_vms.com.
+
+Questions about zlib should be sent to <zlib@gzip.org>, or to Gilles Vollant
+<info@winimage.com> for the Windows DLL version. The zlib home page is
+http://zlib.net/ . Before reporting a problem, please check this site to
+verify that you have the latest version of zlib; otherwise get the latest
+version and check whether the problem still exists or not.
+
+PLEASE read the zlib FAQ http://zlib.net/zlib_faq.html before asking for help.
+
+Mark Nelson <markn@ieee.org> wrote an article about zlib for the Jan. 1997
+issue of Dr. Dobb's Journal; a copy of the article is available at
+http://marknelson.us/1997/01/01/zlib-engine/ .
+
+The changes made in version 1.2.6 are documented in the file ChangeLog.
+
+Unsupported third party contributions are provided in directory contrib/ .
+
+zlib is available in Java using the java.util.zip package, documented at
+http://java.sun.com/developer/technicalArticles/Programming/compression/ .
+
+A Perl interface to zlib written by Paul Marquess <pmqs@cpan.org> is available
+at CPAN (Comprehensive Perl Archive Network) sites, including
+http://search.cpan.org/~pmqs/IO-Compress-Zlib/ .
+
+A Python interface to zlib written by A.M. Kuchling <amk@amk.ca> is
+available in Python 1.5 and later versions, see
+http://docs.python.org/library/zlib.html .
+
+zlib is built into tcl: http://wiki.tcl.tk/4610 .
+
+An experimental package to read and write files in .zip format, written on top
+of zlib by Gilles Vollant <info@winimage.com>, is available in the
+contrib/minizip directory of zlib.
+
+
+Notes for some targets:
+
+- For Windows DLL versions, please see win32/DLL_FAQ.txt
+
+- For 64-bit Irix, deflate.c must be compiled without any optimization. With
+ -O, one libpng test fails. The test works in 32 bit mode (with the -n32
+ compiler flag). The compiler bug has been reported to SGI.
+
+- zlib doesn't work with gcc 2.6.3 on a DEC 3000/300LX under OSF/1 2.1 it works
+ when compiled with cc.
+
+- On Digital Unix 4.0D (formely OSF/1) on AlphaServer, the cc option -std1 is
+ necessary to get gzprintf working correctly. This is done by configure.
+
+- zlib doesn't work on HP-UX 9.05 with some versions of /bin/cc. It works with
+ other compilers. Use "make test" to check your compiler.
+
+- gzdopen is not supported on RISCOS or BEOS.
+
+- For PalmOs, see http://palmzlib.sourceforge.net/
+
+
+Acknowledgments:
+
+ The deflate format used by zlib was defined by Phil Katz. The deflate and
+ zlib specifications were written by L. Peter Deutsch. Thanks to all the
+ people who reported problems and suggested various improvements in zlib; they
+ are too numerous to cite here.

+ ZLIB version 1.2.6 for AS400 installation instructions
+
+I) From an AS400 *SAVF file:
+
+1) Unpacking archive to an AS400 save file
+
+On the AS400:
+
+_ Create the ZLIB AS400 library:
+
+ CRTLIB LIB(ZLIB) TYPE(*PROD) TEXT('ZLIB compression API library')
+
+_ Create a work save file, for example:
+
+ CRTSAVF FILE(ZLIB/ZLIBSAVF)
+
+On a PC connected to the target AS400:
+
+_ Unpack the save file image to a PC file "ZLIBSAVF"
+_ Upload this file into the save file on the AS400, for example
+ using ftp in BINARY mode.
+
+
+2) Populating the ZLIB AS400 source library
+
+On the AS400:
+
+_ Extract the saved objects into the ZLIB AS400 library using:
+
+RSTOBJ OBJ(*ALL) SAVLIB(ZLIB) DEV(*SAVF) SAVF(ZLIB/ZLIBSAVF) RSTLIB(ZLIB)
+
+
+3) Customize installation:
+
+_ Edit CL member ZLIB/TOOLS(COMPILE) and change parameters if needed,
+ according to the comments.
+
+_ Compile this member with:
+
+ CRTCLPGM PGM(ZLIB/COMPILE) SRCFILE(ZLIB/TOOLS) SRCMBR(COMPILE)
+
+
+4) Compile and generate the service program:
+
+_ This can now be done by executing:
+
+ CALL PGM(ZLIB/COMPILE)
+
+
+
+II) From the original source distribution:
+
+1) On the AS400, create the source library:
+
+ CRTLIB LIB(ZLIB) TYPE(*PROD) TEXT('ZLIB compression API library')
+
+2) Create the source files:
+
+ CRTSRCPF FILE(ZLIB/SOURCES) RCDLEN(112) TEXT('ZLIB library modules')
+ CRTSRCPF FILE(ZLIB/H) RCDLEN(112) TEXT('ZLIB library includes')
+ CRTSRCPF FILE(ZLIB/TOOLS) RCDLEN(112) TEXT('ZLIB library control utilities')
+
+3) From the machine hosting the distribution files, upload them (with
+ FTP in text mode, for example) according to the following table:
+
+ Original AS400 AS400 AS400 AS400

+
+
+
+
+Notes: For AS400 ILE RPG programmers, a /copy member defining the ZLIB
+ API prototypes for ILE RPG can be found in ZLIB/H(ZLIB.INC).
+ Please read comments in this member for more information.
+
+ Remember that most foreign textual data are ASCII coded: this
+ implementation does not handle conversion from/to ASCII, so
+ text data code conversions must be done explicitely.
+
+ Mainly for the reason above, always open zipped files in binary mode.

+ ZLib for Ada thick binding (ZLib.Ada)
+ Release 1.3
+
+ZLib.Ada is a thick binding interface to the popular ZLib data
+compression library, available at http://www.gzip.org/zlib/.
+It provides Ada-style access to the ZLib C library.
+
+
+ Here are the main changes since ZLib.Ada 1.2:
+
+- Attension: ZLib.Read generic routine have a initialization requirement
+ for Read_Last parameter now. It is a bit incompartible with previous version,
+ but extends functionality, we could use new parameters Allow_Read_Some and
+ Flush now.
+
+- Added Is_Open routines to ZLib and ZLib.Streams packages.
+
+- Add pragma Assert to check Stream_Element is 8 bit.
+
+- Fix extraction to buffer with exact known decompressed size. Error reported by
+ Steve Sangwine.
+
+- Fix definition of ULong (changed to unsigned_long), fix regression on 64 bits
+ computers. Patch provided by Pascal Obry.
+
+- Add Status_Error exception definition.
+
+- Add pragma Assertion that Ada.Streams.Stream_Element size is 8 bit.
+
+
+ How to build ZLib.Ada under GNAT
+
+You should have the ZLib library already build on your computer, before
+building ZLib.Ada. Make the directory of ZLib.Ada sources current and
+issue the command:
+
+ gnatmake test -largs -L<directory where libz.a is> -lz
+
+Or use the GNAT project file build for GNAT 3.15 or later:
+
+ gnatmake -Pzlib.gpr -L<directory where libz.a is>
+
+
+ How to build ZLib.Ada under Aonix ObjectAda for Win32 7.2.2
+
+1. Make a project with all *.ads and *.adb files from the distribution.
+2. Build the libz.a library from the ZLib C sources.
+3. Rename libz.a to z.lib.
+4. Add the library z.lib to the project.
+5. Add the libc.lib library from the ObjectAda distribution to the project.
+6. Build the executable using test.adb as a main procedure.
+
+
+ How to use ZLib.Ada
+
+The source files test.adb and read.adb are small demo programs that show
+the main functionality of ZLib.Ada.
+
+The routines from the package specifications are commented.

+This is a patched version of zlib, modified to use
+Pentium-Pro-optimized assembly code in the deflation algorithm. The
+files changed/added by this patch are:
+
+README.686
+match.S
+
+The speedup that this patch provides varies, depending on whether the
+compiler used to build the original version of zlib falls afoul of the
+PPro's speed traps. My own tests show a speedup of around 10-20% at
+the default compression level, and 20-30% using -9, against a version
+compiled using gcc 2.7.2.3. Your mileage may vary.
+
+Note that this code has been tailored for the PPro/PII in particular,
+and will not perform particuarly well on a Pentium.
+
+If you are using an assembler other than GNU as, you will have to
+translate match.S to use your assembler's syntax. (Have fun.)

+
+
+Added for zlib 1.1.3:
+
+The patches come from
+http://www.muppetlabs.com/~breadbox/software/assembly.html
+
+To compile zlib with this asm file, copy match.S to the zlib directory
+then do:
+
+CFLAGS="-O3 -DASMV" ./configure
+make OBJA=match.o
+
+
+Update:
+
+I've been ignoring these assembly routines for years, believing that
+gcc's generated code had caught up with it sometime around gcc 2.95
+and the major rearchitecting of the Pentium 4. However, I recently
+learned that, despite what I believed, this code still has some life
+in it. On the Pentium 4 and AMD64 chips, it continues to run about 8%
+faster than the code produced by gcc 4.1.
+
+In acknowledgement of its continuing usefulness, I've altered the
+license to match that of the rest of zlib. Share and Enjoy!

+ * no bit reversal is needed for either the length extra bits or the distance
+ * extra bits.

+ * - Distances pointing before the beginning of the output data are not

+
+Overview
+========
+
+This directory contains an update to the ZLib interface unit,
+distributed by Borland as a Delphi supplemental component.
+
+The original ZLib unit is Copyright (c) 1997,99 Borland Corp.,
+and is based on zlib version 1.0.4. There are a series of bugs
+and security problems associated with that old zlib version, and
+we recommend the users to update their ZLib unit.
+
+
+Summary of modifications
+========================
+
+- Improved makefile, adapted to zlib version 1.2.1.
+
+- Some field types from TZStreamRec are changed from Integer to
+ Longint, for consistency with the zlib.h header, and for 64-bit
+ readiness.
+
+- The zlib_version constant is updated.
+
+- The new Z_RLE strategy has its corresponding symbolic constant.
+
+- The allocation and deallocation functions and function types
+ (TAlloc, TFree, zlibAllocMem and zlibFreeMem) are now cdecl,
+ and _malloc and _free are added as C RTL stubs. As a result,
+ the original C sources of zlib can be compiled out of the box,
+ and linked to the ZLib unit.
+
+
+Suggestions for improvements
+============================
+
+Currently, the ZLib unit provides only a limited wrapper around
+the zlib library, and much of the original zlib functionality is
+missing. Handling compressed file formats like ZIP/GZIP or PNG
+cannot be implemented without having this functionality.
+Applications that handle these formats are either using their own,
+duplicated code, or not using the ZLib unit at all.
+
+Here are a few suggestions:
+
+- Checksum class wrappers around adler32() and crc32(), similar
+ to the Java classes that implement the java.util.zip.Checksum
+ interface.
+
+- The ability to read and write raw deflate streams, without the
+ zlib stream header and trailer. Raw deflate streams are used
+ in the ZIP file format.
+
+- The ability to read and write gzip streams, used in the GZIP
+ file format, and normally produced by the gzip program.
+
+- The ability to select a different compression strategy, useful
+ to PNG and MNG image compression, and to multimedia compression
+ in general. Besides the compression level
+
+ TCompressionLevel = (clNone, clFastest, clDefault, clMax);
+
+ which, in fact, could have used the 'z' prefix and avoided
+ TColor-like symbols
+
+ TCompressionLevel = (zcNone, zcFastest, zcDefault, zcMax);
+
+ there could be a compression strategy
+
+ TCompressionStrategy = (zsDefault, zsFiltered, zsHuffmanOnly, zsRle);
+
+- ZIP and GZIP stream handling via TStreams.

+// In order to sign your assembly you must specify a key to use. Refer to the

+//
+// Use the attributes below to control which key is used for signing.
+//
+// Notes:
+// (*) If no key is specified, the assembly is not signed.
+// (*) KeyName refers to a key that has been installed in the Crypto Service
+// Provider (CSP) on your machine. KeyFile refers to a file which contains
+// a key.
+// (*) If the KeyFile and the KeyName values are both specified, the
+// following processing occurs:
+// (1) If the KeyName can be found in the CSP, that key is used.
+// (2) If the KeyName does not exist and the KeyFile does exist, the key
+// in the KeyFile is installed into the CSP and used.
+// (*) In order to create a KeyFile, you can use the sn.exe (Strong Name) utility.
+// When specifying the KeyFile, the location of the KeyFile should be
+// relative to the project output directory which is
+// %Project Directory%\obj\<configuration>. For example, if your KeyFile is
+// located in the project directory, you would specify the AssemblyKeyFile
+// attribute as [assembly: AssemblyKeyFile("..\\..\\mykey.snk")]
+// (*) Delay Signing is an advanced option - see the Microsoft .NET Framework
+// documentation for more information on this.

+This directory contains a .Net wrapper class library for the ZLib1.dll
+
+The wrapper includes support for inflating/deflating memory buffers,
+.Net streaming wrappers for the gz streams part of zlib, and wrappers
+for the checksum parts of zlib. See DotZLib/UnitTests.cs for examples.
+
+Directory structure:
+--------------------
+
+LICENSE_1_0.txt - License file.
+readme.txt - This file.
+DotZLib.chm - Class library documentation
+DotZLib.build - NAnt build file
+DotZLib.sln - Microsoft Visual Studio 2003 solution file
+
+DotZLib\*.cs - Source files for the class library
+
+Unit tests:
+-----------
+The file DotZLib/UnitTests.cs contains unit tests for use with NUnit 2.1 or higher.
+To include unit tests in the build, define nunit before building.
+
+
+Build instructions:
+-------------------
+
+1. Using Visual Studio.Net 2003:
+ Open DotZLib.sln in VS.Net and build from there. Output file (DotZLib.dll)
+ will be found ./DotZLib/bin/release or ./DotZLib/bin/debug, depending on
+ you are building the release or debug version of the library. Check
+ DotZLib/UnitTests.cs for instructions on how to include unit tests in the
+ build.
+
+2. Using NAnt:
+ Open a command prompt with access to the build environment and run nant
+ in the same directory as the DotZLib.build file.
+ You can define 2 properties on the nant command-line to control the build:
+ debug={true|false} to toggle between release/debug builds (default=true).
+ nunit={true|false} to include or esclude unit tests (default=true).
+ Also the target clean will remove binaries.
+ Output file (DotZLib.dll) will be found in either ./DotZLib/bin/release
+ or ./DotZLib/bin/debug, depending on whether you are building the release
+ or debug version of the library.
+
+ Examples:
+ nant -D:debug=false -D:nunit=false
+ will build a release mode version of the library without unit tests.
+ nant
+ will build a debug version of the library with unit tests
+ nant clean
+ will remove all previously built files.

+ filled the window with output, or when it completes with data in the

+
+ in() and out() are called with a descriptor parameter provided in the

+ information required to do the read or write, as well as accumulated
+ information on the input and output such as totals and check values.
+
+ in() should return zero on failure. out() should return non-zero on
+ failure. If either in() or out() fails, than inflateBack() returns a
+ Z_BUF_ERROR. strm->next_in can be checked for Z_NULL to see whether it
+ was in() or out() that caused in the error. Otherwise, inflateBack()
+ returns Z_STREAM_END on success, Z_DATA_ERROR for an deflate format
+ error, or Z_MEM_ERROR if it could not allocate memory for the state.

+ Process a set of code lengths to create a canonical Huffman code. The
+ code lengths are lens[0..codes-1]. Each length corresponds to the
+ symbols 0..codes-1. The Huffman code is generated by first sorting the
+ symbols by length from short to long, and retaining the symbol order
+ for codes with equal lengths. Then the code starts with all zero bits
+ for the first code of the shortest length, and the codes are integer
+ increments for the same length, and zeros are appended as the length
+ increases. For the deflate format, these bits are stored backwards
+ from their more natural integer increment ordering, and so when the
+ decoding tables are built in the large loop below, the integer codes
+ are incremented backwards.
+
+ This routine assumes, but does not check, that all of the entries in
+ lens[] are in the range 0..MAXBITS. The caller must assure this.
+ 1..MAXBITS is interpreted as that code length. zero means that that
+ symbol does not occur in this code.
+
+ The codes are sorted by computing a count of codes for each length,
+ creating from that a table of starting indices for each length in the
+ sorted table, and then entering the symbols in order in the sorted
+ table. The sorted table is work[], with that space being provided by
+ the caller.

+ * Dec-29-2003 -- I added AMD64 inflate asm support. This version is also

+ * bytes. I've tested the AMD64 code on a Fedora Core 1 + the x86_64 updates
+ * from http://fedora.linux.duke.edu/fc1_x86_64
+ * which is running on an Athlon 64 3000+ / Gigabyte GA-K8VT800M system with
+ * 1GB ram. The 64-bit version is about 4% faster than the 32-bit version,
+ * when decompressing mozilla-source-1.3.tar.gz.
+ *
+ * Mar-13-2003 -- Most of this is derived from inffast.S which is derived from
+ * the gcc -S output of zlib-1.2.0/inffast.c. Zlib-1.2.0 is in beta release at
+ * the moment. I have successfully compiled and tested this code with gcc2.96,
+ * gcc3.2, icc5.0, msvc6.0. It is very close to the speed of inffast.S
+ * compiled with gcc -DNO_MMX, but inffast.S is still faster on the P3 with MMX
+ * enabled. I will attempt to merge the MMX code into this version. Newer

+ Decode literal, length, and distance codes and write out the resulting
+ literal and match bytes until either not enough input or output is
+ available, an end-of-block is encountered, or a data error is encountered.
+ When large enough input and output buffers are supplied to inflate(), for
+ example, a 16K input buffer and a 64K output buffer, more than 95% of the
+ inflate execution time is spent in this routine.
+
+ Entry assumptions:
+
+ state->mode == LEN
+ strm->avail_in >= 6
+ strm->avail_out >= 258
+ start >= strm->avail_out
+ state->bits < 8
+
+ On return, state->mode is one of:
+
+ LEN -- ran out of enough output space or enough available input
+ TYPE -- reached end of block code, inflate() to interpret next block
+ BAD -- error in block data
+
+ Notes:
+
+ - The maximum input bits used by a length/distance pair is 15 bits for the
+ length code, 5 bits for the length extra, 15 bits for the distance code,
+ and 13 bits for the distance extra. This totals 48 bits, or six bytes.
+ Therefore if strm->avail_in >= 6, then there is enough input to avoid
+ checking for available input while decoding.
+
+ - The maximum bytes that a single length/distance pair can output is 258
+ bytes, which is the maximum length that can be coded. inflate_fast()
+ requires strm->avail_out >= 258 for each loop to avoid checking for
+ output space.

+ * inffast.S is a hand tuned assembler version of:
+ *
+ * inffast.c -- fast decoding
+ * Copyright (C) 1995-2003 Mark Adler
+ * For conditions of distribution and use, see copyright notice in zlib.h
+ *
+ * Copyright (C) 2003 Chris Anderson <christop@charm.net>
+ * Please use the copyright conditions above.
+ *
+ * This version (Jan-23-2003) of inflate_fast was coded and tested under
+ * GNU/Linux on a pentium 3, using the gcc-3.2 compiler distribution. On that
+ * machine, I found that gzip style archives decompressed about 20% faster than
+ * the gcc-3.2 -O3 -fomit-frame-pointer compiled version. Your results will
+ * depend on how large of a buffer is used for z_stream.next_in & next_out
+ * (8K-32K worked best for my 256K cpu cache) and how much overhead there is in
+ * stream processing I/O and crc32/addler32. In my case, this routine used
+ * 70% of the cpu time and crc32 used 20%.
+ *
+ * I am confident that this version will work in the general case, but I have
+ * not tested a wide variety of datasets or a wide variety of platforms.
+ *
+ * Jan-24-2003 -- Added -DUSE_MMX define for slightly faster inflating.
+ * It should be a runtime flag instead of compile time flag...
+ *
+ * Jan-26-2003 -- Added runtime check for MMX support with cpuid instruction.
+ * With -DUSE_MMX, only MMX code is compiled. With -DNO_MMX, only non-MMX code
+ * is compiled. Without either option, runtime detection is enabled. Runtime
+ * detection should work on all modern cpus and the recomended algorithm (flip
+ * ID bit on eflags and then use the cpuid instruction) is used in many
+ * multimedia applications. Tested under win2k with gcc-2.95 and gas-2.12
+ * distributed with cygwin3. Compiling with gcc-2.95 -c inffast.S -o
+ * inffast.obj generates a COFF object which can then be linked with MSVC++
+ * compiled code. Tested under FreeBSD 4.7 with gcc-2.95.
+ *
+ * Jan-28-2003 -- Tested Athlon XP... MMX mode is slower than no MMX (and
+ * slower than compiler generated code). Adjusted cpuid check to use the MMX
+ * code only for Pentiums < P4 until I have more data on the P4. Speed
+ * improvment is only about 15% on the Athlon when compared with code generated
+ * with MSVC++. Not sure yet, but I think the P4 will also be slower using the
+ * MMX mode because many of it's x86 ALU instructions execute in .5 cycles and
+ * have less latency than MMX ops. Added code to buffer the last 11 bytes of
+ * the input stream since the MMX code grabs bits in chunks of 32, which
+ * differs from the inffast.c algorithm. I don't think there would have been
+ * read overruns where a page boundary was crossed (a segfault), but there
+ * could have been overruns when next_in ends on unaligned memory (unintialized
+ * memory read).
+ *
+ * Mar-13-2003 -- P4 MMX is slightly slower than P4 NO_MMX. I created a C
+ * version of the non-MMX code so that it doesn't depend on zstrm and zstate
+ * structure offsets which are hard coded in this file. This was last tested
+ * with zlib-1.2.0 which is currently in beta testing, newer versions of this
+ * and inffas86.c can be found at http://www.eetbeetee.com/zlib/ and
+ * http://www.charm.net/~christop/zlib/

+These classes provide a C++ stream interface to the zlib library. It allows you
+to do things like:
+
+ gzofstream outf("blah.gz");
+ outf << "These go into the gzip file " << 123 << endl;
+
+It does this by deriving a specialized stream buffer for gzipped files, which is
+the way Stroustrup would have done it. :->
+
+The gzifstream and gzofstream classes were originally written by Kevin Ruland
+and made available in the zlib contrib/iostream directory. The older version still
+compiles under gcc 2.xx, but not under gcc 3.xx, which sparked the development of
+this version.
+
+The new classes are as standard-compliant as possible, closely following the
+approach of the standard library's fstream classes. It compiles under gcc versions
+3.2 and 3.3, but not under gcc 2.xx. This is mainly due to changes in the standard
+library naming scheme. The new version of gzifstream/gzofstream/gzfilebuf differs
+from the previous one in the following respects:
+- added showmanyc
+- added setbuf, with support for unbuffered output via setbuf(0,0)
+- a few bug fixes of stream behavior
+- gzipped output file opened with default compression level instead of maximum level
+- setcompressionlevel()/strategy() members replaced by single setcompression()
+
+The code is provided "as is", with the permission to use, copy, modify, distribute
+and sell it for any purpose without fee.

+Possible upgrades to gzfilebuf:
+
+- The ability to do putback (e.g. putbackfail)
+
+- The ability to seek (zlib supports this, but could be slow/tricky)
+
+- Simultaneous read/write access (does it make sense?)
+
+- Support for ios_base::ate open mode
+
+- Locale support?
+
+- Check public interface to see which calls give problems
+ (due to dependence on library internals)

+- Override operator<<(ostream&, gzfilebuf*) to allow direct copying

+ *
+ * Dec-29-2003 -- I added AMD64 inflate asm support. This version is also

+ * bytes. I've tested the AMD64 code on a Fedora Core 1 + the x86_64 updates

+ *
+ * Mar-13-2003 -- Most of this is derived from inffast.S which is derived from

+/*
+ Decode literal, length, and distance codes and write out the resulting
+ literal and match bytes until either not enough input or output is
+ available, an end-of-block is encountered, or a data error is encountered.
+ When large enough input and output buffers are supplied to inflate(), for
+ example, a 16K input buffer and a 64K output buffer, more than 95% of the
+ inflate execution time is spent in this routine.
+
+ Entry assumptions:
+
+ state->mode == LEN
+ strm->avail_in >= 6
+ strm->avail_out >= 258
+ start >= strm->avail_out
+ state->bits < 8
+
+ On return, state->mode is one of:
+
+ LEN -- ran out of enough output space or enough available input
+ TYPE -- reached end of block code, inflate() to interpret next block
+ BAD -- error in block data
+
+ Notes:
+
+ - The maximum input bits used by a length/distance pair is 15 bits for the
+ length code, 5 bits for the length extra, 15 bits for the distance code,
+ and 13 bits for the distance extra. This totals 48 bits, or six bytes.
+ Therefore if strm->avail_in >= 6, then there is enough input to avoid
+ checking for available input while decoding.
+
+ - The maximum bytes that a single length/distance pair can output is 258
+ bytes, which is the maximum length that can be coded. inflate_fast()
+ requires strm->avail_out >= 258 for each loop to avoid checking for
+ output space.

+Summary
+-------
+This directory contains ASM implementations of the functions
+longest_match() and inflate_fast(), for 64 bits x86 (both AMD64 and Intel EM64t),
+for use with Microsoft Macro Assembler (x64) for AMD64 and Microsoft C++ 64 bits.
+
+gvmat64.asm is written by Gilles Vollant (2005), by using Brian Raiter 686/32 bits
+ assembly optimized version from Jean-loup Gailly original longest_match function
+
+inffasx64.asm and inffas8664.c were written by Chris Anderson, by optimizing
+ original function from Mark Adler
+
+Use instructions
+----------------
+Assemble the .asm files using MASM and put the object files into the zlib source
+directory. You can also get object files here:
+
+ http://www.winimage.com/zLibDll/zlib124_masm_obj.zip
+
+define ASMV and ASMINF in your project. Include inffas8664.c in your source tree,
+and inffasx64.obj and gvmat64.obj as object to link.
+
+
+Build instructions
+------------------
+run bld_64.bat with Microsoft Macro Assembler (x64) for AMD64 (ml64.exe)
+
+ml64.exe is given with Visual Studio 2005, Windows 2003 server DDK
+
+You can get Windows 2003 server DDK with ml64 and cl for AMD64 from
+ http://www.microsoft.com/whdc/devtools/ddk/default.mspx for low price)

+;
+; this longest_match was written by Brian raiter (1998), optimized for Pentium Pro
+; (and the faster known version of match_init on modern Core 2 Duo and AMD Phenom)
+;
+; for using an assembly version of longest_match, you need define ASMV in project
+;
+; compile the asm file running
+; ml /coff /Zi /c /Flmatch686.lst match686.asm
+; and do not include match686.obj in your project
+;
+; note: contrib of zLib 1.2.3 and earlier contained both a deprecated version for
+; Pentium (prior Pentium Pro) and this version for Pentium Pro and modern processor
+; with autoselect (with cpu detection code)
+; if you want support the old pentium optimization, you can still use these version
+;
+; this file is not optimized for old pentium, but it compatible with all x86 32 bits
+; processor (starting 80386)

+MiniZip - Copyright (c) 1998-2010 - by Gilles Vollant - version 1.1 64 bits from Mathias Svensson
+
+Introduction
+---------------------
+MiniZip 1.1 is built from MiniZip 1.0 by Gilles Vollant ( http://www.winimage.com/zLibDll/minizip.html )
+
+When adding ZIP64 support into minizip it would result into risk of breaking compatibility with minizip 1.0.
+All possible work was done for compatibility.
+
+
+Background
+---------------------
+When adding ZIP64 support Mathias Svensson found that Even Rouault have added ZIP64
+support for unzip.c into minizip for a open source project called gdal ( http://www.gdal.org/ )
+
+That was used as a starting point. And after that ZIP64 support was added to zip.c
+some refactoring and code cleanup was also done.
+
+
+Changed from MiniZip 1.0 to MiniZip 1.1
+---------------------------------------
+* Added ZIP64 support for unzip ( by Even Rouault )
+* Added ZIP64 support for zip ( by Mathias Svensson )
+* Reverted some changed that Even Rouault did.
+* Bunch of patches received from Gulles Vollant that he received for MiniZip from various users.
+* Added unzip patch for BZIP Compression method (patch create by Daniel Borca)
+* Added BZIP Compress method for zip
+* Did some refactoring and code cleanup
+
+
+Credits
+
+ Gilles Vollant - Original MiniZip author
+ Even Rouault - ZIP64 unzip Support
+ Daniel Borca - BZip Compression method support in unzip
+ Mathias Svensson - ZIP64 zip support
+ Mathias Svensson - BZip Compression method support in zip
+
+ Resources
+
+ ZipLayout http://result42.com/projects/ZipFileLayout
+ Command line tool for Windows that shows the layout and information of the headers in a zip archive.
+ Used when debugging and validating the creation of zip files using MiniZip64
+
+
+ ZIP App Note http://www.pkware.com/documents/casestudies/APPNOTE.TXT
+ Zip File specification
+
+
+Notes.
+ * To be able to use BZip compression method in zip64.c or unzip64.c the BZIP2 lib is needed and HAVE_BZIP2 need to be defined.

+
+ Changes
+
+ Oct-2009 - Defined ZPOS64_T to fpos_t on windows and u_int64_t on linux. (might need to find a better why for this)
+ Oct-2009 - Change to fseeko64, ftello64 and fopen64 so large files would work on linux.
+ More if/def section may be needed to support other platforms
+ Oct-2009 - Defined fxxxx64 calls to normal fopen/ftell/fseek so they would compile on windows.
+ (but you should use iowin32.c for windows instead)

+

+ Modifications of Unzip for Zip64

+
+ For more info read MiniZip_info.txt
+
+
+ ------------------------------------------------------------------------------------
+ Decryption code comes from crypt.c by Info-ZIP but has been greatly reduced in terms of
+ compatibility with older software. The following is from the original crypt.c.
+ Code woven in by Terry Thorsen 1/2003.
+
+ Copyright (c) 1990-2000 Info-ZIP. All rights reserved.
+
+ See the accompanying file LICENSE, version 2000-Apr-09 or later
+ (the contents of which are also included in zip.h) for terms of use.
+ If, for some reason, all these files are missing, the Info-ZIP license
+ also may be found at: ftp://ftp.info-zip.org/pub/infozip/license.html
+
+ crypt.c (full version) by Info-ZIP. Last revised: [see crypt.h]
+
+ The encryption/decryption parts of this source code (as opposed to the
+ non-echoing password parts) were originally written in Europe. The
+ whole source package can be freely distributed, including from the USA.
+ (Prior to January 2000, re-export from the US was a violation of US law.)
+
+ This encryption code is a direct transcription of the algorithm from
+ Roger Schlafly, described by Phil Katz in the file appnote.txt. This
+ file (appnote.txt) is distributed with the PKZIP program (even in the
+ version without encryption capabilities).
+
+ ------------------------------------------------------------------------------------
+
+ Changes in unzip.c
+
+ 2007-2008 - Even Rouault - Addition of cpl_unzGetCurrentFileZStreamPos
+ 2007-2008 - Even Rouault - Decoration of symbol names unz* -> cpl_unz*
+ 2007-2008 - Even Rouault - Remove old C style function prototypes
+ 2007-2008 - Even Rouault - Add unzip support for ZIP64
+
+ Copyright (C) 2007-2008 Even Rouault
+
+
+ Oct-2009 - Mathias Svensson - Removed cpl_* from symbol names (Even Rouault added them but since this is now moved to a new project (minizip64) I renamed them again).
+ Oct-2009 - Mathias Svensson - Fixed problem if uncompressed size was > 4G and compressed size was <4G
+ should only read the compressed/uncompressed size from the Zip64 format if
+ the size from normal header was 0xFFFFFFFF
+ Oct-2009 - Mathias Svensson - Applied some bug fixes from paches recived from Gilles Vollant
+ Oct-2009 - Mathias Svensson - Applied support to unzip files with compression mathod BZIP2 (bzip2 lib is required)
+ Patch created by Daniel Borca
+
+ Jan-2010 - back to unzip and minizip 1.0 name scheme, with compatibility layer

+
+ Copyright (C) 1998-2010 Gilles Vollant (minizip) ( http://www.winimage.com/zLibDll/minizip.html )
+
+ Modifications for Zip64 support
+ Copyright (C) 2009-2010 Mathias Svensson ( http://result42.com )
+
+ For more info read MiniZip_info.txt
+
+ Changes
+ Oct-2009 - Mathias Svensson - Remove old C style function prototypes
+ Oct-2009 - Mathias Svensson - Added Zip64 Support when creating new file archives
+ Oct-2009 - Mathias Svensson - Did some code cleanup and refactoring to get better overview of some functions.
+ Oct-2009 - Mathias Svensson - Added zipRemoveExtraInfoBlock to strip extra field data from its ZIP64 data
+ It is used when recreting zip archive with RAW when deleting items from a zip.
+ ZIP64 data is automaticly added to items that needs it, and existing ZIP64 data need to be removed.
+ Oct-2009 - Mathias Svensson - Added support for BZIP2 as compression mode (bzip2 lib is required)
+ Jan-2010 - back to unzip and minizip 1.0 name scheme, with compatibility layer

+This directory contains a Pascal (Delphi, Kylix) interface to the
+zlib data compression library.
+
+
+Directory listing
+=================
+
+zlibd32.mak makefile for Borland C++
+example.pas usage example of zlib
+zlibpas.pas the Pascal interface to zlib
+readme.txt this file
+
+
+Compatibility notes
+===================
+
+- Although the name "zlib" would have been more normal for the
+ zlibpas unit, this name is already taken by Borland's ZLib unit.
+ This is somehow unfortunate, because that unit is not a genuine
+ interface to the full-fledged zlib functionality, but a suite of
+ class wrappers around zlib streams. Other essential features,
+ such as checksums, are missing.
+ It would have been more appropriate for that unit to have a name
+ like "ZStreams", or something similar.
+
+- The C and zlib-supplied types int, uInt, long, uLong, etc. are
+ translated directly into Pascal types of similar sizes (Integer,
+ LongInt, etc.), to avoid namespace pollution. In particular,
+ there is no conversion of unsigned int into a Pascal unsigned
+ integer. The Word type is non-portable and has the same size
+ (16 bits) both in a 16-bit and in a 32-bit environment, unlike
+ Integer. Even if there is a 32-bit Cardinal type, there is no
+ real need for unsigned int in zlib under a 32-bit environment.
+
+- Except for the callbacks, the zlib function interfaces are
+ assuming the calling convention normally used in Pascal
+ (__pascal for DOS and Windows16, __fastcall for Windows32).
+ Since the cdecl keyword is used, the old Turbo Pascal does
+ not work with this interface.
+
+- The gz* function interfaces are not translated, to avoid
+ interfacing problems with the C runtime library. Besides,
+ gzprintf(gzFile file, const char *format, ...)
+ cannot be translated into Pascal.

+Puff -- A Simple Inflate
+3 Mar 2003
+Mark Adler
+madler@alumni.caltech.edu
+
+What this is --
+
+puff.c provides the routine puff() to decompress the deflate data format. It
+does so more slowly than zlib, but the code is about one-fifth the size of the
+inflate code in zlib, and written to be very easy to read.
+
+Why I wrote this --
+
+puff.c was written to document the deflate format unambiguously, by virtue of
+being working C code. It is meant to supplement RFC 1951, which formally
+describes the deflate format. I have received many questions on details of the
+deflate format, and I hope that reading this code will answer those questions.
+puff.c is heavily commented with details of the deflate format, especially
+those little nooks and cranies of the format that might not be obvious from a
+specification.
+
+puff.c may also be useful in applications where code size or memory usage is a
+very limited resource, and speed is not as important.
+
+How to use it --
+
+Well, most likely you should just be reading puff.c and using zlib for actual
+applications, but if you must ...
+
+Include puff.h in your code, which provides this prototype:
+
+int puff(unsigned char *dest, /* pointer to destination pointer */
+ unsigned long *destlen, /* amount of output space */
+ unsigned char *source, /* pointer to source data pointer */
+ unsigned long *sourcelen); /* amount of input available */
+
+Then you can call puff() to decompress a deflate stream that is in memory in
+its entirety at source, to a sufficiently sized block of memory for the
+decompressed data at dest. puff() is the only external symbol in puff.c The
+only C library functions that puff.c needs are setjmp() and longjmp(), which
+are used to simplify error checking in the code to improve readabilty. puff.c
+does no memory allocation, and uses less than 2K bytes off of the stack.
+
+If destlen is not enough space for the uncompressed data, then inflate will
+return an error without writing more than destlen bytes. Note that this means
+that in order to decompress the deflate data successfully, you need to know
+the size of the uncompressed data ahead of time.
+
+If needed, puff() can determine the size of the uncompressed data with no
+output space. This is done by passing dest equal to (unsigned char *)0. Then
+the initial value of *destlen is ignored and *destlen is set to the length of
+the uncompressed data. So if the size of the uncompressed data is not known,
+then two passes of puff() can be used--first to determine the size, and second
+to do the actual inflation after allocating the appropriate memory. Not
+pretty, but it works. (This is one of the reasons you should be using zlib.)
+
+The deflate format is self-terminating. If the deflate stream does not end
+in *sourcelen bytes, puff() will return an error without reading at or past
+endsource.
+
+On return, *sourcelen is updated to the amount of input data consumed, and
+*destlen is updated to the size of the uncompressed data. See the comments
+in puff.c for the possible return codes for puff().

+ * version 2.2, 25 Apr 2010
+ *
+ * puff.c is a simple inflate written to be an unambiguous way to specify the
+ * deflate format. It is not written for speed but rather simplicity. As a
+ * side benefit, this code might actually be useful when small code is more
+ * important than speed, such as bootstrap applications. For typical deflate
+ * data, zlib's inflate() is about four times as fast as puff(). zlib's
+ * inflate compiles to around 20K on my machine, whereas puff.c compiles to
+ * around 4K on my machine (a PowerPC using GNU cc). If the faster decode()
+ * function here is used, then puff() is only twice as slow as zlib's
+ * inflate().
+ *
+ * All dynamically allocated memory comes from the stack. The stack required
+ * is less than 2K bytes. This code is compatible with 16-bit int's and
+ * assumes that long's are at least 32 bits. puff.c uses the short data type,
+ * assumed to be 16 bits, for arrays in order to to conserve memory. The code
+ * works whether integers are stored big endian or little endian.
+ *
+ * In the comments below are "Format notes" that describe the inflate process
+ * and document some of the less obvious aspects of the format. This source
+ * code is meant to supplement RFC 1951, which formally describes the deflate
+ * format:

+ * Format notes:
+ *
+ * - Compressed data that is after the block type if fixed or after the code
+ * description if dynamic is a combination of literals and length/distance
+ * pairs terminated by and end-of-block code. Literals are simply Huffman
+ * coded bytes. A length/distance pair is a coded length followed by a
+ * coded distance to represent a string that occurs earlier in the
+ * uncompressed data that occurs again at the current location.
+ *
+ * - Literals, lengths, and the end-of-block code are combined into a single
+ * code of up to 286 symbols. They are 256 literals (0..255), 29 length
+ * symbols (257..285), and the end-of-block symbol (256).
+ *
+ * - There are 256 possible lengths (3..258), and so 29 symbols are not enough
+ * to represent all of those. Lengths 3..10 and 258 are in fact represented
+ * by just a length symbol. Lengths 11..257 are represented as a symbol and
+ * some number of extra bits that are added as an integer to the base length
+ * of the length symbol. The number of extra bits is determined by the base
+ * length symbol. These are in the static arrays below, lens[] for the base
+ * lengths and lext[] for the corresponding number of extra bits.
+ *
+ * - The reason that 258 gets its own symbol is that the longest length is used
+ * often in highly redundant files. Note that 258 can also be coded as the
+ * base value 227 plus the maximum extra value of 31. While a good deflate
+ * should never do this, it is not an error, and should be decoded properly.
+ *
+ * - If a length is decoded, including its extra bits if any, then it is
+ * followed a distance code. There are up to 30 distance symbols. Again
+ * there are many more possible distances (1..32768), so extra bits are added
+ * to a base value represented by the symbol. The distances 1..4 get their
+ * own symbol, but the rest require extra bits. The base distances and
+ * corresponding number of extra bits are below in the static arrays dist[]
+ * and dext[].
+ *
+ * - Literal bytes are simply written to the output. A length/distance pair is
+ * an instruction to copy previously uncompressed bytes to the output. The
+ * copy is from distance bytes back in the output stream, copying for length
+ * bytes.
+ *
+ * - Distances pointing before the beginning of the output data are not
+ * permitted.
+ *
+ * - Overlapped copies, where the length is greater than the distance, are
+ * allowed and common. For example, a distance of one and a length of 258
+ * simply copies the last byte 258 times. A distance of four and a length of
+ * twelve copies the last four bytes three times. A simple forward copy
+ * ignoring whether the length is greater than the distance or not implements
+ * this correctly. You should not use memcpy() since its behavior is not
+ * defined for overlapped arrays. You should not use memmove() or bcopy()
+ * since though their behavior -is- defined for overlapping arrays, it is
+ * defined to do the wrong thing in this case.

+ * Format notes:
+ *
+ * - A dynamic block starts with a description of the literal/length and
+ * distance codes for that block. New dynamic blocks allow the compressor to
+ * rapidly adapt to changing data with new codes optimized for that data.
+ *
+ * - The codes used by the deflate format are "canonical", which means that
+ * the actual bits of the codes are generated in an unambiguous way simply
+ * from the number of bits in each code. Therefore the code descriptions
+ * are simply a list of code lengths for each symbol.
+ *
+ * - The code lengths are stored in order for the symbols, so lengths are
+ * provided for each of the literal/length symbols, and for each of the
+ * distance symbols.
+ *
+ * - If a symbol is not used in the block, this is represented by a zero as
+ * as the code length. This does not mean a zero-length code, but rather
+ * that no code should be created for this symbol. There is no way in the
+ * deflate format to represent a zero-length code.
+ *
+ * - The maximum number of bits in a code is 15, so the possible lengths for
+ * any code are 1..15.
+ *
+ * - The fact that a length of zero is not permitted for a code has an
+ * interesting consequence. Normally if only one symbol is used for a given
+ * code, then in fact that code could be represented with zero bits. However
+ * in deflate, that code has to be at least one bit. So for example, if
+ * only a single distance base symbol appears in a block, then it will be
+ * represented by a single code of length one, in particular one 0 bit. This
+ * is an incomplete code, since if a 1 bit is received, it has no meaning,
+ * and should result in an error. So incomplete distance codes of one symbol
+ * should be permitted, and the receipt of invalid codes should be handled.
+ *
+ * - It is also possible to have a single literal/length code, but that code
+ * must be the end-of-block code, since every dynamic block has one. This
+ * is not the most efficient way to create an empty block (an empty fixed
+ * block is fewer bits), but it is allowed by the format. So incomplete
+ * literal/length codes of one symbol should also be permitted.
+ *
+ * - If there are only literal codes and no lengths, then there are no distance
+ * codes. This is represented by one distance code with zero bits.
+ *
+ * - The list of up to 286 length/literal lengths and up to 30 distance lengths
+ * are themselves compressed using Huffman codes and run-length encoding. In
+ * the list of code lengths, a 0 symbol means no code, a 1..15 symbol means
+ * that length, and the symbols 16, 17, and 18 are run-length instructions.
+ * Each of 16, 17, and 18 are follwed by extra bits to define the length of
+ * the run. 16 copies the last length 3 to 6 times. 17 represents 3 to 10
+ * zero lengths, and 18 represents 11 to 138 zero lengths. Unused symbols
+ * are common, hence the special coding for zero lengths.
+ *
+ * - The symbols for 0..18 are Huffman coded, and so that code must be
+ * described first. This is simply a sequence of up to 19 three-bit values
+ * representing no code (0) or the code length for that symbol (1..7).
+ *
+ * - A dynamic block starts with three fixed-size counts from which is computed
+ * the number of literal/length code lengths, the number of distance code
+ * lengths, and the number of code length code lengths (ok, you come up with
+ * a better name!) in the code descriptions. For the literal/length and
+ * distance codes, lengths after those provided are considered zero, i.e. no
+ * code. The code length code lengths are received in a permuted order (see
+ * the order[] array below) to make a short code length code length list more
+ * likely. As it turns out, very short and very long codes are less likely
+ * to be seen in a dynamic code description, hence what may appear initially
+ * to be a peculiar ordering.
+ *
+ * - Given the number of literal/length code lengths (nlen) and distance code
+ * lengths (ndist), then they are treated as one long list of nlen + ndist
+ * code lengths. Therefore run-length coding can and often does cross the
+ * boundary between the two sets of lengths.
+ *
+ * - So to summarize, the code description at the start of a dynamic block is
+ * three counts for the number of code lengths for the literal/length codes,
+ * the distance codes, and the code length codes. This is followed by the
+ * code length code lengths, three bits each. This is used to construct the
+ * code length code which is used to read the remainder of the lengths. Then
+ * the literal/length code lengths and distance lengths are read as a single
+ * set of lengths using the code length codes. Codes are constructed from
+ * the resulting two sets of lengths, and then finally you can start
+ * decoding actual compressed data in the block.

+Building instructions for the DLL versions of Zlib 1.2.4
+========================================================
+
+This directory contains projects that build zlib and minizip using
+Microsoft Visual C++ 9.0/10.0, and Visual C++ .
+
+You don't need to build these projects yourself. You can download the
+binaries from:
+ http://www.winimage.com/zLibDll
+
+More information can be found at this site.
+
+first compile assembly code by running
+bld_ml64.bat in contrib\masmx64
+bld_ml32.bat in contrib\masmx86
+
+
+
+
+Build instructions for Visual Studio 2008 (32 bits or 64 bits)
+--------------------------------------------------------------
+- Uncompress current zlib, including all contrib/* files
+- Open contrib\vstudio\vc9\zlibvc.sln with Microsoft Visual C++ 2008.0
+- Or run: vcbuild /rebuild contrib\vstudio\vc9\zlibvc.sln "Release|Win32"
+
+Build instructions for Visual Studio 2010 (32 bits or 64 bits)
+--------------------------------------------------------------
+- Uncompress current zlib, including all contrib/* files
+- Open contrib\vstudio\vc10\zlibvc.sln with Microsoft Visual C++ 2010.0
+
+
+Important
+---------
+- To use zlibwapi.dll in your application, you must define the
+ macro ZLIB_WINAPI when compiling your application's source files.
+
+
+Additional notes
+----------------
+- This DLL, named zlibwapi.dll, is compatible to the old zlib.dll built
+ by Gilles Vollant from the zlib 1.1.x sources, and distributed at
+ http://www.winimage.com/zLibDll
+ It uses the WINAPI calling convention for the exported functions, and
+ includes the minizip functionality. If your application needs that
+ particular build of zlib.dll, you can rename zlibwapi.dll to zlib.dll.
+
+- The new DLL was renamed because there exist several incompatible
+ versions of zlib.dll on the Internet.
+
+- There is also an official DLL build of zlib, named zlib1.dll. This one
+ is exporting the functions using the CDECL convention. See the file
+ win32\DLL_FAQ.txt found in this zlib distribution.
+
+- There used to be a ZLIB_DLL macro in zlib 1.1.x, but now this symbol
+ has a slightly different effect. To avoid compatibility problems, do
+ not define it here.
+

+ Generate tables for a byte-wise 32-bit CRC calculation on the polynomial:
+ x^32+x^26+x^23+x^22+x^16+x^12+x^11+x^10+x^8+x^7+x^5+x^4+x^2+x+1.
+
+ Polynomials over GF(2) are represented in binary, one bit per coefficient,
+ with the lowest powers in the most significant bit. Then adding polynomials
+ is just exclusive-or, and multiplying a polynomial by x is a right shift by
+ one. If we call the above polynomial p, and represent a byte as the
+ polynomial q, also with the lowest power in the most significant bit (so the
+ byte 0xb1 is the polynomial x^7+x^3+x+1), then the CRC is (q*x^32) mod p,
+ where a mod b means the remainder after dividing a by b.
+
+ This calculation is done using the shift-register method of multiplying and
+ taking the remainder. The register is initialized to zero, and for each
+ incoming bit, x^32 is added mod p to the register if the bit is a one (where
+ x^32 mod p is p+x^32 = x^26+...+1), and the register is multiplied mod p by
+ x (which is shifting right by one and adding x^32 mod p if the bit shifted
+ out is a one). We start with the highest power (least significant bit) of
+ q and repeat for all eight bits of q.
+
+ The first table is simply the CRC of all possible eight bit values. This is
+ all the information needed to generate CRCs on data a byte at a time for all
+ combinations of CRC register values and incoming bytes. The remaining tables
+ allow for word-at-a-time CRC calculation for both big-endian and little-
+ endian machines, where a word is four bytes.

+/*
+ * ALGORITHM
+ *
+ * The "deflation" process depends on being able to identify portions
+ * of the input text which are identical to earlier input (within a
+ * sliding window trailing behind the input currently being processed).
+ *
+ * The most straightforward technique turns out to be the fastest for
+ * most input files: try all possible matches and select the longest.
+ * The key feature of this algorithm is that insertions into the string
+ * dictionary are very simple and thus fast, and deletions are avoided
+ * completely. Insertions are performed at each input character, whereas
+ * string matches are performed only when the previous match ends. So it
+ * is preferable to spend more time in matches to allow very fast string
+ * insertions and avoid deletions. The matching algorithm for small
+ * strings is inspired from that of Rabin & Karp. A brute force approach
+ * is used to find longer strings when a small match has been found.
+ * A similar algorithm is used in comic (by Jan-Mark Wams) and freeze
+ * (by Leonid Broukhis).
+ * A previous version of this file used a more sophisticated algorithm
+ * (by Fiala and Greene) which is guaranteed to run in linear amortized
+ * time, but has a larger average cost, uses more memory and is patented.
+ * However the F&G algorithm may be faster for some highly redundant
+ * files if the parameter max_chain_length (described below) is too large.
+ *
+ * ACKNOWLEDGEMENTS
+ *
+ * The idea of lazy evaluation of matches is due to Jan-Mark Wams, and
+ * I found it in 'freeze' written by Leonid Broukhis.
+ * Thanks to many people for bug reports and testing.

+1. Compression algorithm (deflate)
+
+The deflation algorithm used by gzip (also zip and zlib) is a variation of
+LZ77 (Lempel-Ziv 1977, see reference below). It finds duplicated strings in
+the input data. The second occurrence of a string is replaced by a
+pointer to the previous string, in the form of a pair (distance,
+length). Distances are limited to 32K bytes, and lengths are limited
+to 258 bytes. When a string does not occur anywhere in the previous
+32K bytes, it is emitted as a sequence of literal bytes. (In this
+description, `string' must be taken as an arbitrary sequence of bytes,
+and is not restricted to printable characters.)
+
+Literals or match lengths are compressed with one Huffman tree, and
+match distances are compressed with another tree. The trees are stored
+in a compact form at the start of each block. The blocks can have any
+size (except that the compressed data for one block must fit in
+available memory). A block is terminated when deflate() determines that
+it would be useful to start another block with fresh trees. (This is
+somewhat similar to the behavior of LZW-based _compress_.)
+
+Duplicated strings are found using a hash table. All input strings of
+length 3 are inserted in the hash table. A hash index is computed for
+the next 3 bytes. If the hash chain for this index is not empty, all
+strings in the chain are compared with the current input string, and
+the longest match is selected.
+
+The hash chains are searched starting with the most recent strings, to
+favor small distances and thus take advantage of the Huffman encoding.
+The hash chains are singly linked. There are no deletions from the
+hash chains, the algorithm simply discards matches that are too old.
+
+To avoid a worst-case situation, very long hash chains are arbitrarily
+truncated at a certain length, determined by a runtime option (level
+parameter of deflateInit). So deflate() does not always find the longest
+possible match but generally finds a match which is long enough.
+
+deflate() also defers the selection of matches with a lazy evaluation
+mechanism. After a match of length N has been found, deflate() searches for
+a longer match at the next input byte. If a longer match is found, the
+previous match is truncated to a length of one (thus producing a single
+literal byte) and the process of lazy evaluation begins again. Otherwise,
+the original match is kept, and the next match search is attempted only N
+steps later.
+
+The lazy match evaluation is also subject to a runtime parameter. If
+the current match is long enough, deflate() reduces the search for a longer
+match, thus speeding up the whole process. If compression ratio is more
+important than speed, deflate() attempts a complete second search even if
+the first match is already long enough.
+
+The lazy match evaluation is not performed for the fastest compression
+modes (level parameter 1 to 3). For these fast modes, new strings
+are inserted in the hash table only when no match was found, or
+when the match is not too long. This degrades the compression ratio
+but saves time since there are both fewer insertions and fewer searches.
+
+
+2. Decompression algorithm (inflate)
+
+2.1 Introduction
+
+The key question is how to represent a Huffman code (or any prefix code) so
+that you can decode fast. The most important characteristic is that shorter
+codes are much more common than longer codes, so pay attention to decoding the
+short codes fast, and let the long codes take longer to decode.
+
+inflate() sets up a first level table that covers some number of bits of
+input less than the length of longest code. It gets that many bits from the
+stream, and looks it up in the table. The table will tell if the next
+code is that many bits or less and how many, and if it is, it will tell
+the value, else it will point to the next level table for which inflate()
+grabs more bits and tries to decode a longer code.
+
+How many bits to make the first lookup is a tradeoff between the time it
+takes to decode and the time it takes to build the table. If building the
+table took no time (and if you had infinite memory), then there would only
+be a first level table to cover all the way to the longest code. However,
+building the table ends up taking a lot longer for more bits since short
+codes are replicated many times in such a table. What inflate() does is
+simply to make the number of bits in the first table a variable, and then
+to set that variable for the maximum speed.
+
+For inflate, which has 286 possible codes for the literal/length tree, the size
+of the first table is nine bits. Also the distance trees have 30 possible
+values, and the size of the first table is six bits. Note that for each of
+those cases, the table ended up one bit longer than the ``average'' code
+length, i.e. the code length of an approximately flat code which would be a
+little more than eight bits for 286 symbols and a little less than five bits
+for 30 symbols.
+
+
+2.2 More details on the inflate table lookup
+
+Ok, you want to know what this cleverly obfuscated inflate tree actually
+looks like. You are correct that it's not a Huffman tree. It is simply a
+lookup table for the first, let's say, nine bits of a Huffman symbol. The
+symbol could be as short as one bit or as long as 15 bits. If a particular
+symbol is shorter than nine bits, then that symbol's translation is duplicated
+in all those entries that start with that symbol's bits. For example, if the
+symbol is four bits, then it's duplicated 32 times in a nine-bit table. If a
+symbol is nine bits long, it appears in the table once.
+
+If the symbol is longer than nine bits, then that entry in the table points
+to another similar table for the remaining bits. Again, there are duplicated
+entries as needed. The idea is that most of the time the symbol will be short
+and there will only be one table look up. (That's whole idea behind data
+compression in the first place.) For the less frequent long symbols, there
+will be two lookups. If you had a compression method with really long
+symbols, you could have as many levels of lookups as is efficient. For
+inflate, two is enough.
+
+So a table entry either points to another table (in which case nine bits in
+the above example are gobbled), or it contains the translation for the symbol
+and the number of bits to gobble. Then you start again with the next
+ungobbled bit.
+
+You may wonder: why not just have one lookup table for how ever many bits the
+longest symbol is? The reason is that if you do that, you end up spending
+more time filling in duplicate symbol entries than you do actually decoding.
+At least for deflate's output that generates new trees every several 10's of
+kbytes. You can imagine that filling in a 2^15 entry table for a 15-bit code
+would take too long if you're only decoding several thousand symbols. At the
+other extreme, you could make a new table for every bit in the code. In fact,
+that's essentially a Huffman tree. But then you spend too much time
+traversing the tree while decoding, even for short symbols.
+
+So the number of bits for the first lookup table is a trade of the time to
+fill out the table vs. the time spent looking at the second level and above of
+the table.
+
+Here is an example, scaled down:
+
+The code being decoded, with 10 symbols, from 1 to 6 bits long:
+
+A: 0
+B: 10
+C: 1100
+D: 11010
+E: 11011
+F: 11100
+G: 11101
+H: 11110
+I: 111110
+J: 111111
+
+Let's make the first table three bits long (eight entries):
+
+000: A,1
+001: A,1
+010: A,1
+011: A,1
+100: B,2
+101: B,2
+110: -> table X (gobble 3 bits)
+111: -> table Y (gobble 3 bits)
+
+Each entry is what the bits decode as and how many bits that is, i.e. how
+many bits to gobble. Or the entry points to another table, with the number of
+bits to gobble implicit in the size of the table.
+
+Table X is two bits long since the longest code starting with 110 is five bits
+long:
+
+00: C,1
+01: C,1
+10: D,2
+11: E,2
+
+Table Y is three bits long since the longest code starting with 111 is six
+bits long:
+
+000: F,2
+001: F,2
+010: G,2
+011: G,2
+100: H,2
+101: H,2
+110: I,3
+111: J,3
+
+So what we have here are three tables with a total of 20 entries that had to
+be constructed. That's compared to 64 entries for a single table. Or
+compared to 16 entries for a Huffman tree (six two entry tables and one four
+entry table). Assuming that the code ideally represents the probability of
+the symbols, it takes on the average 1.25 lookups per symbol. That's compared
+to one lookup for the single table, or 1.66 lookups per symbol for the
+Huffman tree.
+
+There, I think that gives you a picture of what's going on. For inflate, the
+meaning of a particular symbol is often more than just a letter. It can be a
+byte (a "literal"), or it can be either a length or a distance which
+indicates a base value and a number of bits to fetch after the code that is
+added to the base value. Or it might be the special end-of-block code. The
+data structures created in inftrees.c try to encode all that information
+compactly in the tables.

+Abstract
+
+ This specification defines a lossless compressed data format. The
+ data can be produced or consumed, even for an arbitrarily long
+ sequentially presented input data stream, using only an a priori
+ bounded amount of intermediate storage. The format presently uses
+ the DEFLATE compression method but can be easily extended to use
+ other compression methods. It can be implemented readily in a manner
+ not covered by patents. This specification also defines the ADLER-32
+ checksum (an extension and improvement of the Fletcher checksum),
+ used for detection of data corruption, and provides an algorithm for
+ computing it.

+1. Introduction
+
+ 1.1. Purpose
+
+ The purpose of this specification is to define a lossless
+ compressed data format that:
+
+ * Is independent of CPU type, operating system, file system,
+ and character set, and hence can be used for interchange;
+
+ * Can be produced or consumed, even for an arbitrarily long
+ sequentially presented input data stream, using only an a
+ priori bounded amount of intermediate storage, and hence can
+ be used in data communications or similar structures such as
+ Unix filters;
+
+ * Can use a number of different compression methods;
+
+ * Can be implemented readily in a manner not covered by
+ patents, and hence can be practiced freely.
+
+ The data format defined by this specification does not attempt to
+ allow random access to compressed data.

+
+
+ 1.2. Intended audience
+
+ This specification is intended for use by implementors of software
+ to compress data into zlib format and/or decompress data from zlib
+ format.
+
+ The text of the specification assumes a basic background in
+ programming at the level of bits and other primitive data
+ representations.
+
+ 1.3. Scope
+
+ The specification specifies a compressed data format that can be
+ used for in-memory compression of a sequence of arbitrary bytes.
+
+ 1.4. Compliance
+
+ Unless otherwise indicated below, a compliant decompressor must be
+ able to accept and decompress any data set that conforms to all
+ the specifications presented here; a compliant compressor must
+ produce data sets that conform to all the specifications presented
+ here.
+
+ 1.5. Definitions of terms and conventions used
+
+ byte: 8 bits stored or transmitted as a unit (same as an octet).
+ (For this specification, a byte is exactly 8 bits, even on
+ machines which store a character on a number of bits different
+ from 8.) See below, for the numbering of bits within a byte.
+
+ 1.6. Changes from previous versions
+
+ Version 3.1 was the first public release of this specification.
+ In version 3.2, some terminology was changed and the Adler-32
+ sample code was rewritten for clarity. In version 3.3, the
+ support for a preset dictionary was introduced, and the
+ specification was converted to RFC style.
+
+2. Detailed specification
+
+ 2.1. Overall conventions
+
+ In the diagrams below, a box like this:
+
+ +---+
+ | | <-- the vertical bars might be missing
+ +---+
+
+
+
+
+Deutsch & Gailly Informational [Page 3]
+
+RFC 1950 ZLIB Compressed Data Format Specification May 1996
+
+
+ represents one byte; a box like this:
+
+ +==============+
+ | |
+ +==============+
+
+ represents a variable number of bytes.
+
+ Bytes stored within a computer do not have a "bit order", since
+ they are always treated as a unit. However, a byte considered as
+ an integer between 0 and 255 does have a most- and least-
+ significant bit, and since we write numbers with the most-
+ significant digit on the left, we also write bytes with the most-
+ significant bit on the left. In the diagrams below, we number the
+ bits of a byte so that bit 0 is the least-significant bit, i.e.,
+ the bits are numbered:
+
+ +--------+
+ |76543210|
+ +--------+
+
+ Within a computer, a number may occupy multiple bytes. All
+ multi-byte numbers in the format described here are stored with
+ the MOST-significant byte first (at the lower memory address).
+ For example, the decimal number 520 is stored as:
+
+ 0 1
+ +--------+--------+
+ |00000010|00001000|
+ +--------+--------+
+ ^ ^
+ | |
+ | + less significant byte = 8
+ + more significant byte = 2 x 256
+
+ 2.2. Data format
+
+ A zlib stream has the following structure:
+
+ 0 1
+ +---+---+
+ |CMF|FLG| (more-->)
+ +---+---+
+
+
+
+
+
+
+
+
+Deutsch & Gailly Informational [Page 4]
+
+RFC 1950 ZLIB Compressed Data Format Specification May 1996
+
+
+ (if FLG.FDICT set)
+
+ 0 1 2 3
+ +---+---+---+---+
+ | DICTID | (more-->)
+ +---+---+---+---+
+
+ +=====================+---+---+---+---+
+ |...compressed data...| ADLER32 |
+ +=====================+---+---+---+---+
+
+ Any data which may appear after ADLER32 are not part of the zlib
+ stream.
+
+ CMF (Compression Method and flags)
+ This byte is divided into a 4-bit compression method and a 4-
+ bit information field depending on the compression method.
+
+ bits 0 to 3 CM Compression method
+ bits 4 to 7 CINFO Compression info
+
+ CM (Compression method)
+ This identifies the compression method used in the file. CM = 8
+ denotes the "deflate" compression method with a window size up
+ to 32K. This is the method used by gzip and PNG (see
+ references [1] and [2] in Chapter 3, below, for the reference
+ documents). CM = 15 is reserved. It might be used in a future
+ version of this specification to indicate the presence of an
+ extra field before the compressed data.
+
+ CINFO (Compression info)
+ For CM = 8, CINFO is the base-2 logarithm of the LZ77 window
+ size, minus eight (CINFO=7 indicates a 32K window size). Values
+ of CINFO above 7 are not allowed in this version of the
+ specification. CINFO is not defined in this specification for
+ CM not equal to 8.
+
+ FLG (FLaGs)
+ This flag byte is divided as follows:
+
+ bits 0 to 4 FCHECK (check bits for CMF and FLG)
+ bit 5 FDICT (preset dictionary)
+ bits 6 to 7 FLEVEL (compression level)
+
+ The FCHECK value must be such that CMF and FLG, when viewed as
+ a 16-bit unsigned integer stored in MSB order (CMF*256 + FLG),
+ is a multiple of 31.
+
+
+
+
+Deutsch & Gailly Informational [Page 5]
+
+RFC 1950 ZLIB Compressed Data Format Specification May 1996
+
+
+ FDICT (Preset dictionary)
+ If FDICT is set, a DICT dictionary identifier is present
+ immediately after the FLG byte. The dictionary is a sequence of
+ bytes which are initially fed to the compressor without
+ producing any compressed output. DICT is the Adler-32 checksum
+ of this sequence of bytes (see the definition of ADLER32
+ below). The decompressor can use this identifier to determine
+ which dictionary has been used by the compressor.
+
+ FLEVEL (Compression level)
+ These flags are available for use by specific compression
+ methods. The "deflate" method (CM = 8) sets these flags as
+ follows:
+
+ 0 - compressor used fastest algorithm
+ 1 - compressor used fast algorithm
+ 2 - compressor used default algorithm
+ 3 - compressor used maximum compression, slowest algorithm
+
+ The information in FLEVEL is not needed for decompression; it
+ is there to indicate if recompression might be worthwhile.
+
+ compressed data
+ For compression method 8, the compressed data is stored in the
+ deflate compressed data format as described in the document
+ "DEFLATE Compressed Data Format Specification" by L. Peter
+ Deutsch. (See reference [3] in Chapter 3, below)
+
+ Other compressed data formats are not specified in this version
+ of the zlib specification.
+
+ ADLER32 (Adler-32 checksum)
+ This contains a checksum value of the uncompressed data
+ (excluding any dictionary data) computed according to Adler-32
+ algorithm. This algorithm is a 32-bit extension and improvement
+ of the Fletcher algorithm, used in the ITU-T X.224 / ISO 8073
+ standard. See references [4] and [5] in Chapter 3, below)
+
+ Adler-32 is composed of two sums accumulated per byte: s1 is
+ the sum of all bytes, s2 is the sum of all s1 values. Both sums
+ are done modulo 65521. s1 is initialized to 1, s2 to zero. The
+ Adler-32 checksum is stored as s2*65536 + s1 in most-
+ significant-byte first (network) order.

+
+
+ 2.3. Compliance
+
+ A compliant compressor must produce streams with correct CMF, FLG
+ and ADLER32, but need not support preset dictionaries. When the
+ zlib data format is used as part of another standard data format,
+ the compressor may use only preset dictionaries that are specified
+ by this other data format. If this other format does not use the
+ preset dictionary feature, the compressor must not set the FDICT
+ flag.
+
+ A compliant decompressor must check CMF, FLG, and ADLER32, and
+ provide an error indication if any of these have incorrect values.
+ A compliant decompressor must give an error indication if CM is
+ not one of the values defined in this specification (only the
+ value 8 is permitted in this version), since another value could
+ indicate the presence of new features that would cause subsequent
+ data to be interpreted incorrectly. A compliant decompressor must
+ give an error indication if FDICT is set and DICTID is not the
+ identifier of a known preset dictionary. A decompressor may
+ ignore FLEVEL and still be compliant. When the zlib data format
+ is being used as a part of another standard format, a compliant
+ decompressor must support all the preset dictionaries specified by
+ the other format. When the other format does not use the preset
+ dictionary feature, a compliant decompressor must reject any
+ stream in which the FDICT flag is set.

+8. Appendix: Rationale
+
+ 8.1. Preset dictionaries
+
+ A preset dictionary is specially useful to compress short input
+ sequences. The compressor can take advantage of the dictionary
+ context to encode the input in a more compact manner. The
+ decompressor can be initialized with the appropriate context by
+ virtually decompressing a compressed version of the dictionary
+ without producing any output. However for certain compression
+ algorithms such as the deflate algorithm this operation can be
+ achieved without actually performing any decompression.
+
+ The compressor and the decompressor must use exactly the same
+ dictionary. The dictionary may be fixed or may be chosen among a
+ certain number of predefined dictionaries, according to the kind
+ of input data. The decompressor can determine which dictionary has
+ been chosen by the compressor by checking the dictionary
+ identifier. This document does not specify the contents of
+ predefined dictionaries, since the optimal dictionaries are
+ application specific. Standard data formats using this feature of
+ the zlib specification must precisely define the allowed
+ dictionaries.
+
+ 8.2. The Adler-32 algorithm
+
+ The Adler-32 algorithm is much faster than the CRC32 algorithm yet
+ still provides an extremely low probability of undetected errors.
+
+ The modulo on unsigned long accumulators can be delayed for 5552
+ bytes, so the modulo operation time is negligible. If the bytes
+ are a, b, c, the second sum is 3a + 2b + c + 3, and so is position
+ and order sensitive, unlike the first sum, which is just a
+ checksum. That 65521 is prime is important to avoid a possible
+ large class of two-byte errors that leave the check unchanged.
+ (The Fletcher checksum uses 255, which is not prime and which also
+ makes the Fletcher check insensitive to single byte changes 0 <->
+ 255.)
+
+ The sum s1 is initialized to 1 instead of zero to make the length
+ of the sequence part of s2, so that the length does not have to be
+ checked separately. (Any sequence of zeroes has a Fletcher
+ checksum of zero.)

+
+
+9. Appendix: Sample code
+
+ The following C code computes the Adler-32 checksum of a data buffer.
+ It is written for clarity, not for speed. The sample code is in the
+ ANSI C programming language. Non C users may find it easier to read
+ with these hints:
+
+ & Bitwise AND operator.
+ >> Bitwise right shift operator. When applied to an
+ unsigned quantity, as here, right shift inserts zero bit(s)
+ at the left.
+ << Bitwise left shift operator. Left shift inserts zero
+ bit(s) at the right.
+ ++ "n++" increments the variable n.
+ % modulo operator: a % b is the remainder of a divided by b.
+
+ #define BASE 65521 /* largest prime smaller than 65536 */
+
+ /*
+ Update a running Adler-32 checksum with the bytes buf[0..len-1]
+ and return the updated checksum. The Adler-32 checksum should be
+ initialized to 1.
+
+ Usage example:
+
+ unsigned long adler = 1L;
+
+ while (read_buffer(buffer, length) != EOF) {
+ adler = update_adler32(adler, buffer, length);
+ }
+ if (adler != original_adler) error();
+ */
+ unsigned long update_adler32(unsigned long adler,
+ unsigned char *buf, int len)
+ {
+ unsigned long s1 = adler & 0xffff;
+ unsigned long s2 = (adler >> 16) & 0xffff;
+ int n;
+
+ for (n = 0; n < len; n++) {
+ s1 = (s1 + buf[n]) % BASE;
+ s2 = (s2 + s1) % BASE;
+ }
+ return (s2 << 16) + s1;
+ }
+
+ /* Return the adler32 of the bytes buf[0..len-1] */

+1. Introduction
+
+ 1.1. Purpose
+
+ The purpose of this specification is to define a lossless
+ compressed data format that:
+ * Is independent of CPU type, operating system, file system,
+ and character set, and hence can be used for interchange;
+ * Can be produced or consumed, even for an arbitrarily long
+ sequentially presented input data stream, using only an a
+ priori bounded amount of intermediate storage, and hence
+ can be used in data communications or similar structures
+ such as Unix filters;
+ * Compresses data with efficiency comparable to the best
+ currently available general-purpose compression methods,
+ and in particular considerably better than the "compress"
+ program;
+ * Can be implemented readily in a manner not covered by
+ patents, and hence can be practiced freely;
+
+
+
+Deutsch Informational [Page 2]
+
+RFC 1951 DEFLATE Compressed Data Format Specification May 1996
+
+
+ * Is compatible with the file format produced by the current
+ widely used gzip utility, in that conforming decompressors
+ will be able to read data produced by the existing gzip
+ compressor.
+
+ The data format defined by this specification does not attempt to:
+
+ * Allow random access to compressed data;
+ * Compress specialized data (e.g., raster graphics) as well
+ as the best currently available specialized algorithms.
+
+ A simple counting argument shows that no lossless compression
+ algorithm can compress every possible input data set. For the
+ format defined here, the worst case expansion is 5 bytes per 32K-
+ byte block, i.e., a size increase of 0.015% for large data sets.
+ English text usually compresses by a factor of 2.5 to 3;
+ executable files usually compress somewhat less; graphical data
+ such as raster images may compress much more.
+
+ 1.2. Intended audience
+
+ This specification is intended for use by implementors of software
+ to compress data into "deflate" format and/or decompress data from
+ "deflate" format.
+
+ The text of the specification assumes a basic background in
+ programming at the level of bits and other primitive data
+ representations. Familiarity with the technique of Huffman coding
+ is helpful but not required.
+
+ 1.3. Scope
+
+ The specification specifies a method for representing a sequence
+ of bytes as a (usually shorter) sequence of bits, and a method for
+ packing the latter bit sequence into bytes.
+
+ 1.4. Compliance
+
+ Unless otherwise indicated below, a compliant decompressor must be
+ able to accept and decompress any data set that conforms to all
+ the specifications presented here; a compliant compressor must
+ produce data sets that conform to all the specifications presented
+ here.
+
+ 1.5. Definitions of terms and conventions used
+
+ Byte: 8 bits stored or transmitted as a unit (same as an octet).
+ For this specification, a byte is exactly 8 bits, even on machines
+
+
+
+Deutsch Informational [Page 3]
+
+RFC 1951 DEFLATE Compressed Data Format Specification May 1996
+
+
+ which store a character on a number of bits different from eight.
+ See below, for the numbering of bits within a byte.
+
+ String: a sequence of arbitrary bytes.
+
+ 1.6. Changes from previous versions
+
+ There have been no technical changes to the deflate format since
+ version 1.1 of this specification. In version 1.2, some
+ terminology was changed. Version 1.3 is a conversion of the
+ specification to RFC style.
+
+2. Compressed representation overview
+
+ A compressed data set consists of a series of blocks, corresponding
+ to successive blocks of input data. The block sizes are arbitrary,
+ except that non-compressible blocks are limited to 65,535 bytes.
+
+ Each block is compressed using a combination of the LZ77 algorithm
+ and Huffman coding. The Huffman trees for each block are independent
+ of those for previous or subsequent blocks; the LZ77 algorithm may
+ use a reference to a duplicated string occurring in a previous block,
+ up to 32K input bytes before.
+
+ Each block consists of two parts: a pair of Huffman code trees that
+ describe the representation of the compressed data part, and a
+ compressed data part. (The Huffman trees themselves are compressed
+ using Huffman encoding.) The compressed data consists of a series of
+ elements of two types: literal bytes (of strings that have not been
+ detected as duplicated within the previous 32K input bytes), and
+ pointers to duplicated strings, where a pointer is represented as a
+ pair <length, backward distance>. The representation used in the
+ "deflate" format limits distances to 32K bytes and lengths to 258
+ bytes, but does not limit the size of a block, except for
+ uncompressible blocks, which are limited as noted above.
+
+ Each type of value (literals, distances, and lengths) in the
+ compressed data is represented using a Huffman code, using one code
+ tree for literals and lengths and a separate code tree for distances.
+ The code trees for each block appear in a compact form just before
+ the compressed data for that block.

+
+3. Detailed specification
+
+ 3.1. Overall conventions In the diagrams below, a box like this:
+
+ +---+
+ | | <-- the vertical bars might be missing
+ +---+
+
+ represents one byte; a box like this:
+
+ +==============+
+ | |
+ +==============+
+
+ represents a variable number of bytes.
+
+ Bytes stored within a computer do not have a "bit order", since
+ they are always treated as a unit. However, a byte considered as
+ an integer between 0 and 255 does have a most- and least-
+ significant bit, and since we write numbers with the most-
+ significant digit on the left, we also write bytes with the most-
+ significant bit on the left. In the diagrams below, we number the
+ bits of a byte so that bit 0 is the least-significant bit, i.e.,
+ the bits are numbered:
+
+ +--------+
+ |76543210|
+ +--------+
+
+ Within a computer, a number may occupy multiple bytes. All
+ multi-byte numbers in the format described here are stored with
+ the least-significant byte first (at the lower memory address).
+ For example, the decimal number 520 is stored as:
+
+ 0 1
+ +--------+--------+
+ |00001000|00000010|
+ +--------+--------+
+ ^ ^
+ | |
+ | + more significant byte = 2 x 256
+ + less significant byte = 8
+
+ 3.1.1. Packing into bytes
+
+ This document does not address the issue of the order in which
+ bits of a byte are transmitted on a bit-sequential medium,
+ since the final data format described here is byte- rather than
+
+
+
+Deutsch Informational [Page 5]
+
+RFC 1951 DEFLATE Compressed Data Format Specification May 1996
+
+
+ bit-oriented. However, we describe the compressed block format
+ in below, as a sequence of data elements of various bit
+ lengths, not a sequence of bytes. We must therefore specify
+ how to pack these data elements into bytes to form the final
+ compressed byte sequence:
+
+ * Data elements are packed into bytes in order of
+ increasing bit number within the byte, i.e., starting
+ with the least-significant bit of the byte.
+ * Data elements other than Huffman codes are packed
+ starting with the least-significant bit of the data
+ element.
+ * Huffman codes are packed starting with the most-
+ significant bit of the code.
+
+ In other words, if one were to print out the compressed data as
+ a sequence of bytes, starting with the first byte at the
+ *right* margin and proceeding to the *left*, with the most-
+ significant bit of each byte on the left as usual, one would be
+ able to parse the result from right to left, with fixed-width
+ elements in the correct MSB-to-LSB order and Huffman codes in
+ bit-reversed order (i.e., with the first bit of the code in the
+ relative LSB position).
+
+ 3.2. Compressed block format
+
+ 3.2.1. Synopsis of prefix and Huffman coding
+
+ Prefix coding represents symbols from an a priori known
+ alphabet by bit sequences (codes), one code for each symbol, in
+ a manner such that different symbols may be represented by bit
+ sequences of different lengths, but a parser can always parse
+ an encoded string unambiguously symbol-by-symbol.
+
+ We define a prefix code in terms of a binary tree in which the
+ two edges descending from each non-leaf node are labeled 0 and
+ 1 and in which the leaf nodes correspond one-for-one with (are
+ labeled with) the symbols of the alphabet; then the code for a
+ symbol is the sequence of 0's and 1's on the edges leading from
+ the root to the leaf labeled with that symbol. For example:
+
+
+
+
+
+
+
+
+
+
+
+Deutsch Informational [Page 6]
+
+RFC 1951 DEFLATE Compressed Data Format Specification May 1996
+
+
+ /\ Symbol Code
+ 0 1 ------ ----
+ / \ A 00
+ /\ B B 1
+ 0 1 C 011
+ / \ D 010
+ A /\
+ 0 1
+ / \
+ D C
+
+ A parser can decode the next symbol from an encoded input
+ stream by walking down the tree from the root, at each step
+ choosing the edge corresponding to the next input bit.
+
+ Given an alphabet with known symbol frequencies, the Huffman
+ algorithm allows the construction of an optimal prefix code
+ (one which represents strings with those symbol frequencies
+ using the fewest bits of any possible prefix codes for that
+ alphabet). Such a code is called a Huffman code. (See
+ reference [1] in Chapter 5, references for additional
+ information on Huffman codes.)
+
+ Note that in the "deflate" format, the Huffman codes for the
+ various alphabets must not exceed certain maximum code lengths.
+ This constraint complicates the algorithm for computing code
+ lengths from symbol frequencies. Again, see Chapter 5,
+ references for details.
+
+ 3.2.2. Use of Huffman coding in the "deflate" format
+
+ The Huffman codes used for each alphabet in the "deflate"
+ format have two additional rules:
+
+ * All codes of a given bit length have lexicographically
+ consecutive values, in the same order as the symbols
+ they represent;
+
+ * Shorter codes lexicographically precede longer codes.
+
+
+
+
+
+
+
+
+
+
+
+
+Deutsch Informational [Page 7]
+
+RFC 1951 DEFLATE Compressed Data Format Specification May 1996
+
+
+ We could recode the example above to follow this rule as
+ follows, assuming that the order of the alphabet is ABCD:
+
+ Symbol Code
+ ------ ----
+ A 10
+ B 0
+ C 110
+ D 111
+
+ I.e., 0 precedes 10 which precedes 11x, and 110 and 111 are
+ lexicographically consecutive.
+
+ Given this rule, we can define the Huffman code for an alphabet
+ just by giving the bit lengths of the codes for each symbol of
+ the alphabet in order; this is sufficient to determine the
+ actual codes. In our example, the code is completely defined
+ by the sequence of bit lengths (2, 1, 3, 3). The following
+ algorithm generates the codes as integers, intended to be read
+ from most- to least-significant bit. The code lengths are
+ initially in tree[I].Len; the codes are produced in
+ tree[I].Code.
+
+ 1) Count the number of codes for each code length. Let
+ bl_count[N] be the number of codes of length N, N >= 1.
+
+ 2) Find the numerical value of the smallest code for each
+ code length:
+
+ code = 0;
+ bl_count[0] = 0;
+ for (bits = 1; bits <= MAX_BITS; bits++) {
+ code = (code + bl_count[bits-1]) << 1;
+ next_code[bits] = code;
+ }
+
+ 3) Assign numerical values to all codes, using consecutive
+ values for all codes of the same length with the base
+ values determined at step 2. Codes that are never used
+ (which have a bit length of zero) must not be assigned a
+ value.
+
+ for (n = 0; n <= max_code; n++) {
+ len = tree[n].Len;
+ if (len != 0) {
+ tree[n].Code = next_code[len];
+ next_code[len]++;
+ }
+
+
+
+Deutsch Informational [Page 8]
+
+RFC 1951 DEFLATE Compressed Data Format Specification May 1996
+
+
+ }
+
+ Example:
+
+ Consider the alphabet ABCDEFGH, with bit lengths (3, 3, 3, 3,
+ 3, 2, 4, 4). After step 1, we have:
+
+ N bl_count[N]
+ - -----------
+ 2 1
+ 3 5
+ 4 2
+
+ Step 2 computes the following next_code values:
+
+ N next_code[N]
+ - ------------
+ 1 0
+ 2 0
+ 3 2
+ 4 14
+
+ Step 3 produces the following code values:
+
+ Symbol Length Code
+ ------ ------ ----
+ A 3 010
+ B 3 011
+ C 3 100
+ D 3 101
+ E 3 110
+ F 2 00
+ G 4 1110
+ H 4 1111
+
+ 3.2.3. Details of block format
+
+ Each block of compressed data begins with 3 header bits
+ containing the following data:
+
+ first bit BFINAL
+ next 2 bits BTYPE
+
+ Note that the header bits do not necessarily begin on a byte
+ boundary, since a block does not necessarily occupy an integral
+ number of bytes.
+
+
+
+
+
+Deutsch Informational [Page 9]
+
+RFC 1951 DEFLATE Compressed Data Format Specification May 1996
+
+
+ BFINAL is set if and only if this is the last block of the data
+ set.
+
+ BTYPE specifies how the data are compressed, as follows:
+
+ 00 - no compression
+ 01 - compressed with fixed Huffman codes
+ 10 - compressed with dynamic Huffman codes
+ 11 - reserved (error)
+
+ The only difference between the two compressed cases is how the
+ Huffman codes for the literal/length and distance alphabets are
+ defined.
+
+ In all cases, the decoding algorithm for the actual data is as
+ follows:
+
+ do
+ read block header from input stream.
+ if stored with no compression
+ skip any remaining bits in current partially
+ processed byte
+ read LEN and NLEN (see next section)
+ copy LEN bytes of data to output
+ otherwise
+ if compressed with dynamic Huffman codes
+ read representation of code trees (see
+ subsection below)
+ loop (until end of block code recognized)
+ decode literal/length value from input stream
+ if value < 256
+ copy value (literal byte) to output stream
+ otherwise
+ if value = end of block (256)
+ break from loop
+ otherwise (value = 257..285)
+ decode distance from input stream
+
+ move backwards distance bytes in the output
+ stream, and copy length bytes from this
+ position to the output stream.
+ end loop
+ while not last block
+
+ Note that a duplicated string reference may refer to a string
+ in a previous block; i.e., the backward distance may cross one
+ or more block boundaries. However a distance cannot refer past
+ the beginning of the output stream. (An application using a
+
+
+
+Deutsch Informational [Page 10]
+
+RFC 1951 DEFLATE Compressed Data Format Specification May 1996
+
+
+ preset dictionary might discard part of the output stream; a
+ distance can refer to that part of the output stream anyway)
+ Note also that the referenced string may overlap the current
+ position; for example, if the last 2 bytes decoded have values
+ X and Y, a string reference with <length = 5, distance = 2>
+ adds X,Y,X,Y,X to the output stream.
+
+ We now specify each compression method in turn.
+
+ 3.2.4. Non-compressed blocks (BTYPE=00)
+
+ Any bits of input up to the next byte boundary are ignored.
+ The rest of the block consists of the following information:
+
+ 0 1 2 3 4...
+ +---+---+---+---+================================+
+ | LEN | NLEN |... LEN bytes of literal data...|
+ +---+---+---+---+================================+
+
+ LEN is the number of data bytes in the block. NLEN is the
+ one's complement of LEN.
+
+ 3.2.5. Compressed blocks (length and distance codes)
+
+ As noted above, encoded data blocks in the "deflate" format
+ consist of sequences of symbols drawn from three conceptually
+ distinct alphabets: either literal bytes, from the alphabet of
+ byte values (0..255), or <length, backward distance> pairs,
+ where the length is drawn from (3..258) and the distance is
+ drawn from (1..32,768). In fact, the literal and length
+ alphabets are merged into a single alphabet (0..285), where
+ values 0..255 represent literal bytes, the value 256 indicates
+ end-of-block, and values 257..285 represent length codes
+ (possibly in conjunction with extra bits following the symbol
+ code) as follows:

+ 3.2.6. Compression with fixed Huffman codes (BTYPE=01)
+
+ The Huffman codes for the two alphabets are fixed, and are not
+ represented explicitly in the data. The Huffman code lengths
+ for the literal/length alphabet are:
+
+ Lit Value Bits Codes
+ --------- ---- -----
+ 0 - 143 8 00110000 through

+ 11000111
+
+
+
+Deutsch Informational [Page 12]
+
+RFC 1951 DEFLATE Compressed Data Format Specification May 1996
+
+
+ The code lengths are sufficient to generate the actual codes,
+ as described above; we show the codes in the table for added
+ clarity. Literal/length values 286-287 will never actually
+ occur in the compressed data, but participate in the code
+ construction.
+
+ Distance codes 0-31 are represented by (fixed-length) 5-bit
+ codes, with possible additional bits as shown in the table
+ shown in Paragraph 3.2.5, above. Note that distance codes 30-
+ 31 will never actually occur in the compressed data.
+
+ 3.2.7. Compression with dynamic Huffman codes (BTYPE=10)
+
+ The Huffman codes for the two alphabets appear in the block
+ immediately after the header bits and before the actual
+ compressed data, first the literal/length code and then the
+ distance code. Each code is defined by a sequence of code
+ lengths, as discussed in Paragraph 3.2.2, above. For even
+ greater compactness, the code length sequences themselves are
+ compressed using a Huffman code. The alphabet for code lengths
+ is as follows:
+
+ 0 - 15: Represent code lengths of 0 - 15
+ 16: Copy the previous code length 3 - 6 times.
+ The next 2 bits indicate repeat length
+ (0 = 3, ... , 3 = 6)
+ Example: Codes 8, 16 (+2 bits 11),
+ 16 (+2 bits 10) will expand to
+ 12 code lengths of 8 (1 + 6 + 5)
+ 17: Repeat a code length of 0 for 3 - 10 times.
+ (3 bits of length)
+ 18: Repeat a code length of 0 for 11 - 138 times
+ (7 bits of length)
+
+ A code length of 0 indicates that the corresponding symbol in
+ the literal/length or distance alphabet will not occur in the
+ block, and should not participate in the Huffman code
+ construction algorithm given earlier. If only one distance
+ code is used, it is encoded using one bit, not zero bits; in
+ this case there is a single code length of one, with one unused
+ code. One distance code of zero bits means that there are no
+ distance codes used at all (the data is all literals).
+
+ We can now define the format of the block:
+
+ 5 Bits: HLIT, # of Literal/Length codes - 257 (257 - 286)
+ 5 Bits: HDIST, # of Distance codes - 1 (1 - 32)
+ 4 Bits: HCLEN, # of Code Length codes - 4 (4 - 19)
+
+
+
+Deutsch Informational [Page 13]
+
+RFC 1951 DEFLATE Compressed Data Format Specification May 1996
+
+
+ (HCLEN + 4) x 3 bits: code lengths for the code length
+ alphabet given just above, in the order: 16, 17, 18,
+ 0, 8, 7, 9, 6, 10, 5, 11, 4, 12, 3, 13, 2, 14, 1, 15
+
+ These code lengths are interpreted as 3-bit integers
+ (0-7); as above, a code length of 0 means the
+ corresponding symbol (literal/length or distance code
+ length) is not used.
+
+ HLIT + 257 code lengths for the literal/length alphabet,
+ encoded using the code length Huffman code
+
+ HDIST + 1 code lengths for the distance alphabet,
+ encoded using the code length Huffman code
+
+ The actual compressed data of the block,
+ encoded using the literal/length and distance Huffman
+ codes
+
+ The literal/length symbol 256 (end of data),
+ encoded using the literal/length Huffman code
+
+ The code length repeat codes can cross from HLIT + 257 to the
+ HDIST + 1 code lengths. In other words, all code lengths form
+ a single sequence of HLIT + HDIST + 258 values.
+
+ 3.3. Compliance
+
+ A compressor may limit further the ranges of values specified in
+ the previous section and still be compliant; for example, it may
+ limit the range of backward pointers to some value smaller than
+ 32K. Similarly, a compressor may limit the size of blocks so that
+ a compressible block fits in memory.
+
+ A compliant decompressor must accept the full range of possible
+ values defined in the previous section, and must accept blocks of
+ arbitrary size.
+
+4. Compression algorithm details
+
+ While it is the intent of this document to define the "deflate"
+ compressed data format without reference to any particular
+ compression algorithm, the format is related to the compressed
+ formats produced by LZ77 (Lempel-Ziv 1977, see reference [2] below);
+ since many variations of LZ77 are patented, it is strongly
+ recommended that the implementor of a compressor follow the general
+ algorithm presented here, which is known not to be patented per se.
+ The material in this section is not part of the definition of the
+
+
+
+Deutsch Informational [Page 14]
+
+RFC 1951 DEFLATE Compressed Data Format Specification May 1996
+
+
+ specification per se, and a compressor need not follow it in order to
+ be compliant.
+
+ The compressor terminates a block when it determines that starting a
+ new block with fresh trees would be useful, or when the block size
+ fills up the compressor's block buffer.
+
+ The compressor uses a chained hash table to find duplicated strings,
+ using a hash function that operates on 3-byte sequences. At any
+ given point during compression, let XYZ be the next 3 input bytes to
+ be examined (not necessarily all different, of course). First, the
+ compressor examines the hash chain for XYZ. If the chain is empty,
+ the compressor simply writes out X as a literal byte and advances one
+ byte in the input. If the hash chain is not empty, indicating that
+ the sequence XYZ (or, if we are unlucky, some other 3 bytes with the
+ same hash function value) has occurred recently, the compressor
+ compares all strings on the XYZ hash chain with the actual input data
+ sequence starting at the current point, and selects the longest
+ match.
+
+ The compressor searches the hash chains starting with the most recent
+ strings, to favor small distances and thus take advantage of the
+ Huffman encoding. The hash chains are singly linked. There are no
+ deletions from the hash chains; the algorithm simply discards matches
+ that are too old. To avoid a worst-case situation, very long hash
+ chains are arbitrarily truncated at a certain length, determined by a
+ run-time parameter.
+
+ To improve overall compression, the compressor optionally defers the
+ selection of matches ("lazy matching"): after a match of length N has
+ been found, the compressor searches for a longer match starting at
+ the next input byte. If it finds a longer match, it truncates the
+ previous match to a length of one (thus producing a single literal
+ byte) and then emits the longer match. Otherwise, it emits the
+ original match, and, as described above, advances N bytes before
+ continuing.
+
+ Run-time parameters also control this "lazy match" procedure. If
+ compression ratio is most important, the compressor attempts a
+ complete second search regardless of the length of the first match.
+ In the normal case, if the current match is "long enough", the
+ compressor reduces the search for a longer match, thus speeding up
+ the process. If speed is most important, the compressor inserts new
+ strings in the hash table only when no match was found, or when the
+ match is not "too long". This degrades the compression ratio but
+ saves time since there are both fewer insertions and fewer searches.

+
+ This specification defines a lossless compressed data format that is
+ compatible with the widely used GZIP utility. The format includes a
+ cyclic redundancy check value for detecting data corruption. The
+ format presently uses the DEFLATE method of compression but can be
+ easily extended to use other compression methods. The format can be
+ implemented readily in a manner not covered by patents.

+1. Introduction
+
+ 1.1. Purpose
+
+ The purpose of this specification is to define a lossless
+ compressed data format that:
+
+ * Is independent of CPU type, operating system, file system,
+ and character set, and hence can be used for interchange;
+ * Can compress or decompress a data stream (as opposed to a
+ randomly accessible file) to produce another data stream,
+ using only an a priori bounded amount of intermediate
+ storage, and hence can be used in data communications or
+ similar structures such as Unix filters;
+ * Compresses data with efficiency comparable to the best
+ currently available general-purpose compression methods,
+ and in particular considerably better than the "compress"
+ program;
+ * Can be implemented readily in a manner not covered by
+ patents, and hence can be practiced freely;
+ * Is compatible with the file format produced by the current
+ widely used gzip utility, in that conforming decompressors
+ will be able to read data produced by the existing gzip
+ compressor.
+
+
+
+
+Deutsch Informational [Page 2]
+
+RFC 1952 GZIP File Format Specification May 1996
+
+
+ The data format defined by this specification does not attempt to:
+
+ * Provide random access to compressed data;
+ * Compress specialized data (e.g., raster graphics) as well as
+ the best currently available specialized algorithms.
+
+ 1.2. Intended audience
+
+ This specification is intended for use by implementors of software
+ to compress data into gzip format and/or decompress data from gzip
+ format.
+
+ The text of the specification assumes a basic background in
+ programming at the level of bits and other primitive data
+ representations.
+
+ 1.3. Scope
+
+ The specification specifies a compression method and a file format
+ (the latter assuming only that a file can store a sequence of
+ arbitrary bytes). It does not specify any particular interface to
+ a file system or anything about character sets or encodings
+ (except for file names and comments, which are optional).
+
+ 1.4. Compliance
+
+ Unless otherwise indicated below, a compliant decompressor must be
+ able to accept and decompress any file that conforms to all the
+ specifications presented here; a compliant compressor must produce
+ files that conform to all the specifications presented here. The
+ material in the appendices is not part of the specification per se
+ and is not relevant to compliance.
+
+ 1.5. Definitions of terms and conventions used
+
+ byte: 8 bits stored or transmitted as a unit (same as an octet).
+ (For this specification, a byte is exactly 8 bits, even on
+ machines which store a character on a number of bits different
+ from 8.) See below for the numbering of bits within a byte.
+
+ 1.6. Changes from previous versions
+
+ There have been no technical changes to the gzip format since
+ version 4.1 of this specification. In version 4.2, some
+ terminology was changed, and the sample CRC code was rewritten for
+ clarity and to eliminate the requirement for the caller to do pre-
+ and post-conditioning. Version 4.3 is a conversion of the
+ specification to RFC style.

+
+2. Detailed specification
+
+ 2.1. Overall conventions
+
+ In the diagrams below, a box like this:
+
+ +---+
+ | | <-- the vertical bars might be missing
+ +---+
+
+ represents one byte; a box like this:
+
+ +==============+
+ | |
+ +==============+
+
+ represents a variable number of bytes.
+
+ Bytes stored within a computer do not have a "bit order", since
+ they are always treated as a unit. However, a byte considered as
+ an integer between 0 and 255 does have a most- and least-
+ significant bit, and since we write numbers with the most-
+ significant digit on the left, we also write bytes with the most-
+ significant bit on the left. In the diagrams below, we number the
+ bits of a byte so that bit 0 is the least-significant bit, i.e.,
+ the bits are numbered:
+
+ +--------+
+ |76543210|
+ +--------+
+
+ This document does not address the issue of the order in which
+ bits of a byte are transmitted on a bit-sequential medium, since
+ the data format described here is byte- rather than bit-oriented.
+
+ Within a computer, a number may occupy multiple bytes. All
+ multi-byte numbers in the format described here are stored with
+ the least-significant byte first (at the lower memory address).
+ For example, the decimal number 520 is stored as:
+
+ 0 1
+ +--------+--------+
+ |00001000|00000010|
+ +--------+--------+
+ ^ ^
+ | |
+ | + more significant byte = 2 x 256
+ + less significant byte = 8

+
+
+ 2.2. File format
+
+ A gzip file consists of a series of "members" (compressed data
+ sets). The format of each member is specified in the following
+ section. The members simply appear one after another in the file,
+ with no additional information before, between, or after them.
+
+ 2.3. Member format
+
+ Each member has the following structure:
+
+ +---+---+---+---+---+---+---+---+---+---+
+ |ID1|ID2|CM |FLG| MTIME |XFL|OS | (more-->)
+ +---+---+---+---+---+---+---+---+---+---+
+
+ (if FLG.FEXTRA set)
+
+ +---+---+=================================+
+ | XLEN |...XLEN bytes of "extra field"...| (more-->)
+ +---+---+=================================+
+
+ (if FLG.FNAME set)
+
+ +=========================================+
+ |...original file name, zero-terminated...| (more-->)
+ +=========================================+
+
+ (if FLG.FCOMMENT set)
+
+ +===================================+
+ |...file comment, zero-terminated...| (more-->)
+ +===================================+
+
+ (if FLG.FHCRC set)
+
+ +---+---+
+ | CRC16 |
+ +---+---+
+
+ +=======================+
+ |...compressed blocks...| (more-->)
+ +=======================+
+
+ 0 1 2 3 4 5 6 7
+ +---+---+---+---+---+---+---+---+
+ | CRC32 | ISIZE |
+ +---+---+---+---+---+---+---+---+
+
+

+
+
+ 2.3.1. Member header and trailer
+
+ ID1 (IDentification 1)
+ ID2 (IDentification 2)
+ These have the fixed values ID1 = 31 (0x1f, \037), ID2 = 139
+ (0x8b, \213), to identify the file as being in gzip format.
+
+ CM (Compression Method)
+ This identifies the compression method used in the file. CM
+ = 0-7 are reserved. CM = 8 denotes the "deflate"
+ compression method, which is the one customarily used by
+ gzip and which is documented elsewhere.
+
+ FLG (FLaGs)
+ This flag byte is divided into individual bits as follows:
+
+ bit 0 FTEXT
+ bit 1 FHCRC
+ bit 2 FEXTRA
+ bit 3 FNAME
+ bit 4 FCOMMENT
+ bit 5 reserved
+ bit 6 reserved
+ bit 7 reserved
+
+ If FTEXT is set, the file is probably ASCII text. This is
+ an optional indication, which the compressor may set by
+ checking a small amount of the input data to see whether any
+ non-ASCII characters are present. In case of doubt, FTEXT
+ is cleared, indicating binary data. For systems which have
+ different file formats for ascii text and binary data, the
+ decompressor can use FTEXT to choose the appropriate format.
+ We deliberately do not specify the algorithm used to set
+ this bit, since a compressor always has the option of
+ leaving it cleared and a decompressor always has the option
+ of ignoring it and letting some other program handle issues
+ of data conversion.
+
+ If FHCRC is set, a CRC16 for the gzip header is present,
+ immediately before the compressed data. The CRC16 consists
+ of the two least significant bytes of the CRC32 for all
+ bytes of the gzip header up to and not including the CRC16.
+ [The FHCRC bit was never set by versions of gzip up to
+ 1.2.4, even though it was documented with a different
+ meaning in gzip 1.2.4.]
+
+ If FEXTRA is set, optional extra fields are present, as
+ described in a following section.
+
+
+
+Deutsch Informational [Page 6]
+
+RFC 1952 GZIP File Format Specification May 1996
+
+
+ If FNAME is set, an original file name is present,
+ terminated by a zero byte. The name must consist of ISO
+ 8859-1 (LATIN-1) characters; on operating systems using
+ EBCDIC or any other character set for file names, the name
+ must be translated to the ISO LATIN-1 character set. This
+ is the original name of the file being compressed, with any
+ directory components removed, and, if the file being
+ compressed is on a file system with case insensitive names,
+ forced to lower case. There is no original file name if the
+ data was compressed from a source other than a named file;
+ for example, if the source was stdin on a Unix system, there
+ is no file name.
+
+ If FCOMMENT is set, a zero-terminated file comment is
+ present. This comment is not interpreted; it is only
+ intended for human consumption. The comment must consist of
+ ISO 8859-1 (LATIN-1) characters. Line breaks should be
+ denoted by a single line feed character (10 decimal).
+
+ Reserved FLG bits must be zero.
+
+ MTIME (Modification TIME)
+ This gives the most recent modification time of the original
+ file being compressed. The time is in Unix format, i.e.,
+ seconds since 00:00:00 GMT, Jan. 1, 1970. (Note that this
+ may cause problems for MS-DOS and other systems that use
+ local rather than Universal time.) If the compressed data
+ did not come from a file, MTIME is set to the time at which
+ compression started. MTIME = 0 means no time stamp is
+ available.
+
+ XFL (eXtra FLags)
+ These flags are available for use by specific compression
+ methods. The "deflate" method (CM = 8) sets these flags as
+ follows:
+
+ XFL = 2 - compressor used maximum compression,
+ slowest algorithm
+ XFL = 4 - compressor used fastest algorithm
+
+ OS (Operating System)
+ This identifies the type of file system on which compression
+ took place. This may be useful in determining end-of-line
+ convention for text files. The currently defined values are
+ as follows:

+ OS, 0 for all others). The compressor must set all reserved
+ bits to zero.
+
+ A compliant decompressor must check ID1, ID2, and CM, and
+ provide an error indication if any of these have incorrect
+ values. It must examine FEXTRA/XLEN, FNAME, FCOMMENT and FHCRC
+ at least so it can skip over the optional fields if they are
+ present. It need not examine any other part of the header or
+ trailer; in particular, a decompressor may ignore FTEXT and OS
+ and always produce binary output, and still be compliant. A
+ compliant decompressor must give an error indication if any
+ reserved bit is non-zero, since such a bit could indicate the
+ presence of a new field that would cause subsequent data to be
+ interpreted incorrectly.

+
+ The most widely used implementation of gzip compression, and the

+ implementation is a de facto standard, we mention some more of its
+ features here. Again, the material in this section is not part of
+ the specification per se, and implementations need not follow it to
+ be compliant.
+
+ When compressing or decompressing a file, gzip preserves the
+ protection, ownership, and modification time attributes on the local
+ file system, since there is no provision for representing protection
+ attributes in the gzip file format itself. Since the file format
+ includes a modification time, the gzip decompressor provides a
+ command line switch that assigns the modification time from the file,
+ rather than the local modification time of the compressed input, to
+ the decompressed output.
+
+8. Appendix: Sample CRC Code
+
+ The following sample code represents a practical implementation of
+ the CRC (Cyclic Redundancy Check). (See also ISO 3309 and ITU-T V.42
+ for a formal specification.)
+
+ The sample code is in the ANSI C programming language. Non C users
+ may find it easier to read with these hints:

+A Fast Method for Identifying Plain Text Files
+==============================================
+
+
+Introduction
+------------
+
+Given a file coming from an unknown source, it is sometimes desirable
+to find out whether the format of that file is plain text. Although
+this may appear like a simple task, a fully accurate detection of the
+file type requires heavy-duty semantic analysis on the file contents.
+It is, however, possible to obtain satisfactory results by employing
+various heuristics.
+
+Previous versions of PKZip and other zip-compatible compression tools
+were using a crude detection scheme: if more than 80% (4/5) of the bytes
+found in a certain buffer are within the range [7..127], the file is
+labeled as plain text, otherwise it is labeled as binary. A prominent
+limitation of this scheme is the restriction to Latin-based alphabets.
+Other alphabets, like Greek, Cyrillic or Asian, make extensive use of
+the bytes within the range [128..255], and texts using these alphabets
+are most often misidentified by this scheme; in other words, the rate
+of false negatives is sometimes too high, which means that the recall
+is low. Another weakness of this scheme is a reduced precision, due to
+the false positives that may occur when binary files containing large
+amounts of textual characters are misidentified as plain text.
+
+In this article we propose a new, simple detection scheme that features
+a much increased precision and a near-100% recall. This scheme is
+designed to work on ASCII, Unicode and other ASCII-derived alphabets,
+and it handles single-byte encodings (ISO-8859, MacRoman, KOI8, etc.)
+and variable-sized encodings (ISO-2022, UTF-8, etc.). Wider encodings
+(UCS-2/UTF-16 and UCS-4/UTF-32) are not handled, however.
+
+
+The Algorithm
+-------------
+
+The algorithm works by dividing the set of bytecodes [0..255] into three
+categories:
+- The white list of textual bytecodes:
+ 9 (TAB), 10 (LF), 13 (CR), 32 (SPACE) to 255.
+- The gray list of tolerated bytecodes:
+ 7 (BEL), 8 (BS), 11 (VT), 12 (FF), 26 (SUB), 27 (ESC).
+- The black list of undesired, non-textual bytecodes:
+ 0 (NUL) to 6, 14 to 31.
+
+If a file contains at least one byte that belongs to the white list and
+no byte that belongs to the black list, then the file is categorized as
+plain text; otherwise, it is categorized as binary. (The boundary case,
+when the file is empty, automatically falls into the latter category.)
+
+
+Rationale
+---------
+
+The idea behind this algorithm relies on two observations.
+
+The first observation is that, although the full range of 7-bit codes
+[0..127] is properly specified by the ASCII standard, most control
+characters in the range [0..31] are not used in practice. The only
+widely-used, almost universally-portable control codes are 9 (TAB),
+10 (LF) and 13 (CR). There are a few more control codes that are
+recognized on a reduced range of platforms and text viewers/editors:
+7 (BEL), 8 (BS), 11 (VT), 12 (FF), 26 (SUB) and 27 (ESC); but these
+codes are rarely (if ever) used alone, without being accompanied by
+some printable text. Even the newer, portable text formats such as
+XML avoid using control characters outside the list mentioned here.
+
+The second observation is that most of the binary files tend to contain
+control characters, especially 0 (NUL). Even though the older text
+detection schemes observe the presence of non-ASCII codes from the range
+[128..255], the precision rarely has to suffer if this upper range is
+labeled as textual, because the files that are genuinely binary tend to
+contain both control characters and codes from the upper range. On the
+other hand, the upper range needs to be labeled as textual, because it
+is used by virtually all ASCII extensions. In particular, this range is
+used for encoding non-Latin scripts.
+
+Since there is no counting involved, other than simply observing the
+presence or the absence of some byte values, the algorithm produces
+consistent results, regardless what alphabet encoding is being used.
+(If counting were involved, it could be possible to obtain different
+results on a text encoded, say, using ISO-8859-16 versus UTF-8.)
+
+There is an extra category of plain text files that are "polluted" with
+one or more black-listed codes, either by mistake or by peculiar design
+considerations. In such cases, a scheme that tolerates a small fraction
+of black-listed codes would provide an increased recall (i.e. more true
+positives). This, however, incurs a reduced precision overall, since
+false positives are more likely to appear in binary files that contain
+large chunks of textual data. Furthermore, "polluted" plain text should
+be regarded as binary by general-purpose text detection schemes, because
+general-purpose text processing algorithms might not be applicable.
+Under this premise, it is safe to say that our detection method provides
+a near-100% recall.
+
+Experiments have been run on many files coming from various platforms
+and applications. We tried plain text files, system logs, source code,
+formatted office documents, compiled object code, etc. The results
+confirm the optimistic assumptions about the capabilities of this
+algorithm.

+/*
+ Examine all possible Huffman codes for a given number of symbols and a
+ maximum code length in bits to determine the maximum table size for zilb's
+ inflate. Only complete Huffman codes are counted.
+
+ Two codes are considered distinct if the vectors of the number of codes per
+ length are not identical. So permutations of the symbol assignments result
+ in the same code for the counting, as do permutations of the assignments of
+ the bit values to the codes (i.e. only canonical codes are counted).
+
+ We build a code from shorter to longer lengths, determining how many symbols
+ are coded at each length. At each step, we have how many symbols remain to
+ be coded, what the last code length used was, and how many bit patterns of
+ that length remain unused. Then we add one to the code length and double the
+ number of unused patterns to graduate to the next code length. We then
+ assign all portions of the remaining symbols to that code length that
+ preserve the properties of a correct and eventually complete code. Those
+ properties are: we cannot use more bit patterns than are available; and when
+ all the symbols are used, there are exactly zero possible bit patterns
+ remaining.
+
+ The inflate Huffman decoding algorithm uses two-level lookup tables for
+ speed. There is a single first-level table to decode codes up to root bits
+ in length (root == 9 in the current inflate implementation). The table
+ has 1 << root entries and is indexed by the next root bits of input. Codes
+ shorter than root bits have replicated table entries, so that the correct
+ entry is pointed to regardless of the bits that follow the short code. If
+ the code is longer than root bits, then the table entry points to a second-
+ level table. The size of that table is determined by the longest code with
+ that root-bit prefix. If that longest code has length len, then the table
+ has size 1 << (len - root), to index the remaining bits in that set of
+ codes. Each subsequent root-bit prefix then has its own sub-table. The
+ total number of table entries required by the code is calculated
+ incrementally as the number of codes at each bit length is populated. When
+ all of the codes are shorter than root bits, then root is reduced to the
+ longest code length, resulting in a single, smaller, one-level table.
+
+ The inflate algorithm also provides for small values of root (relative to
+ the log2 of the number of symbols), where the shortest code has more bits
+ than root. In that case, root is increased to the length of the shortest
+ code. This program, by design, does not handle that case, so it is verified
+ that the number of symbols is less than 2^(root + 1).
+
+ In order to speed up the examination (by about ten orders of magnitude for
+ the default arguments), the intermediate states in the build-up of a code
+ are remembered and previously visited branches are pruned. The memory
+ required for this will increase rapidly with the total number of symbols and
+ the maximum code length in bits. However this is a very small price to pay
+ for the vast speedup.
+
+ First, all of the possible Huffman codes are counted, and reachable
+ intermediate states are noted by a non-zero count in a saved-results array.
+ Second, the intermediate states that lead to (root + 1) bit or longer codes
+ are used to look at all sub-codes from those junctures for their inflate
+ memory usage. (The amount of memory used is not affected by the number of
+ codes of root bits or less in length.) Third, the visited states in the
+ construction of those sub-codes and the associated calculation of the table
+ size is recalled in order to avoid recalculating from the same juncture.
+ Beginning the code examination at (root + 1) bit codes, which is enabled by
+ identifying the reachable nodes, accounts for about six of the orders of
+ magnitude of improvement for the default arguments. About another four
+ orders of magnitude come from not revisiting previous states. Out of
+ approximately 2x10^16 possible Huffman codes, only about 2x10^6 sub-codes
+ need to be examined to cover all of the possible table memory usage cases
+ for the default arguments of 286 symbols limited to 15-bit codes.
+
+ Note that an unsigned long long type is used for counting. It is quite easy
+ to exceed the capacity of an eight-byte integer with a large number of
+ symbols and a large maximum code length, so multiple-precision arithmetic
+ would need to replace the unsigned long long arithmetic in that case. This
+ program will abort if an overflow occurs. The big_t type identifies where
+ the counting takes place.
+
+ An unsigned long long type is also used for calculating the number of
+ possible codes remaining at the maximum length. This limits the maximum
+ code length to the number of bits in a long long minus the number of bits
+ needed to represent the symbols in a flat code. The code_t type identifies
+ where the bit pattern counting takes place.

+/* fitblk.c: example of fitting compressed output to a specified size
+ Not copyrighted -- provided to the public domain
+ Version 1.1 25 November 2004 Mark Adler */
+
+/* Version history:
+ 1.0 24 Nov 2004 First version
+ 1.1 25 Nov 2004 Change deflateInit2() to deflateInit()
+ Use fixed-size, stack-allocated raw buffers
+ Simplify code moving compression to subroutines
+ Use assert() for internal errors
+ Add detailed description of approach
+ */
+
+/* Approach to just fitting a requested compressed size:
+
+ fitblk performs three compression passes on a portion of the input
+ data in order to determine how much of that input will compress to
+ nearly the requested output block size. The first pass generates
+ enough deflate blocks to produce output to fill the requested
+ output size plus a specfied excess amount (see the EXCESS define
+ below). The last deflate block may go quite a bit past that, but
+ is discarded. The second pass decompresses and recompresses just
+ the compressed data that fit in the requested plus excess sized
+ buffer. The deflate process is terminated after that amount of
+ input, which is less than the amount consumed on the first pass.
+ The last deflate block of the result will be of a comparable size
+ to the final product, so that the header for that deflate block and
+ the compression ratio for that block will be about the same as in
+ the final product. The third compression pass decompresses the
+ result of the second step, but only the compressed data up to the
+ requested size minus an amount to allow the compressed stream to
+ complete (see the MARGIN define below). That will result in a
+ final compressed stream whose length is less than or equal to the
+ requested size. Assuming sufficient input and a requested size
+ greater than a few hundred bytes, the shortfall will typically be
+ less than ten bytes.
+
+ If the input is short enough that the first compression completes
+ before filling the requested output size, then that compressed
+ stream is return with no recompression.
+
+ EXCESS is chosen to be just greater than the shortfall seen in a
+ two pass approach similar to the above. That shortfall is due to
+ the last deflate block compressing more efficiently with a smaller
+ header on the second pass. EXCESS is set to be large enough so
+ that there is enough uncompressed data for the second pass to fill
+ out the requested size, and small enough so that the final deflate
+ block of the second pass will be close in size to the final deflate
+ block of the third and final pass. MARGIN is chosen to be just
+ large enough to assure that the final compression has enough room
+ to complete in all cases.

+ gun [ -t ] [ name ... ]
+
+ decompresses the data in the named gzip files. If no arguments are given,
+ gun will decompress from stdin to stdout. The names must end in .gz, -gz,
+ .z, -z, _z, or .Z. The uncompressed data will be written to a file name
+ with the suffix stripped. On success, the original file is deleted. On
+ failure, the output file is deleted. For most failures, the command will
+ continue to process the remaining names on the command line. A memory
+ allocation failure will abort the command. If -t is specified, then the
+ listed files or stdin will be tested as gzip files for integrity (without
+ checking for a proper suffix), no output will be written, and no files
+ will be deleted.
+
+ Like gzip, gun allows concatenated gzip streams and will decompress them,
+ writing all of the uncompressed data to the output. Unlike gzip, gun allows
+ an empty file on input, and will produce no error writing an empty output
+ file.
+
+ gun will also decompress files made by Unix compress, which uses LZW
+ compression. These files are automatically detected by virtue of their
+ magic header bytes. Since the end of Unix compress stream is marked by the
+ end-of-file, they cannot be concantenated. If a Unix compress stream is
+ encountered in an input file, it is the last stream in that file.
+
+ Like gunzip and uncompress, the file attributes of the orignal compressed
+ file are maintained in the final uncompressed file, to the extent that the
+ user permissions allow it.
+
+ On my Mac OS X PowerPC G4, gun is almost twice as fast as gunzip (version
+ 1.2.4) is on the same file, when gun is linked with zlib 1.2.2. Also the
+ LZW decompression provided by gun is about twice as fast as the standard
+ Unix uncompress command.

+/*
+ gzappend takes a gzip file and appends to it, compressing files from the
+ command line or data from stdin. The gzip file is written to directly, to
+ avoid copying that file, in case it's large. Note that this results in the
+ unfriendly behavior that if gzappend fails, the gzip file is corrupted.
+
+ This program was written to illustrate the use of the new Z_BLOCK option of
+ zlib 1.2.x's inflate() function. This option returns from inflate() at each
+ block boundary to facilitate locating and modifying the last block bit at
+ the start of the final deflate block. Also whether using Z_BLOCK or not,
+ another required feature of zlib 1.2.x is that inflate() now provides the
+ number of unusued bits in the last input byte used. gzappend will not work
+ with versions of zlib earlier than 1.2.1.
+
+ gzappend first decompresses the gzip file internally, discarding all but
+ the last 32K of uncompressed data, and noting the location of the last block
+ bit and the number of unused bits in the last byte of the compressed data.
+ The gzip trailer containing the CRC-32 and length of the uncompressed data
+ is verified. This trailer will be later overwritten.
+
+ Then the last block bit is cleared by seeking back in the file and rewriting
+ the byte that contains it. Seeking forward, the last byte of the compressed
+ data is saved along with the number of unused bits to initialize deflate.
+
+ A deflate process is initialized, using the last 32K of the uncompressed
+ data from the gzip file to initialize the dictionary. If the total
+ uncompressed data was less than 32K, then all of it is used to initialize
+ the dictionary. The deflate output bit buffer is also initialized with the
+ last bits from the original deflate stream. From here on, the data to
+ append is simply compressed using deflate, and written to the gzip file.
+ When that is complete, the new CRC-32 and uncompressed length are written
+ as the trailer of the gzip file.

+ gzjoin takes one or more gzip files on the command line and writes out a
+ single gzip file that will uncompress to the concatenation of the
+ uncompressed data from the individual gzip files. gzjoin does this without
+ having to recompress any of the data and without having to calculate a new
+ crc32 for the concatenated uncompressed data. gzjoin does however have to
+ decompress all of the input data in order to find the bits in the compressed
+ data that need to be modified to concatenate the streams.
+
+ gzjoin does not do an integrity check on the input gzip files other than
+ checking the gzip header and decompressing the compressed data. They are
+ otherwise assumed to be complete and correct.
+
+ Each joint between gzip files removes at least 18 bytes of previous trailer
+ and subsequent header, and inserts an average of about three bytes to the
+ compressed data in order to connect the streams. The output gzip file
+ has a minimal ten-byte gzip header with no file name or modification time.
+
+ This program was written to illustrate the use of the Z_BLOCK option of
+ inflate() and the crc32_combine() function. gzjoin will not compile with
+ versions of zlib earlier than 1.2.3.

+ gzlog provides a mechanism for frequently appending short strings to a gzip
+ file that is efficient both in execution time and compression ratio. The
+ strategy is to write the short strings in an uncompressed form to the end of
+ the gzip file, only compressing when the amount of uncompressed data has
+ reached a given threshold.
+
+ gzlog also provides protection against interruptions in the process due to
+ system crashes. The status of the operation is recorded in an extra field
+ in the gzip file, and is only updated once the gzip file is brought to a
+ valid state. The last data to be appended or compressed is saved in an
+ auxiliary file, so that if the operation is interrupted, it can be completed
+ the next time an append operation is attempted.
+
+ gzlog maintains another auxiliary file with the last 32K of data from the
+ compressed portion, which is preloaded for the compression of the subsequent
+ data. This minimizes the impact to the compression ratio of appending.
+ */
+
+/*
+ Operations Concept:
+
+ Files (log name "foo"):
+ foo.gz -- gzip file with the complete log
+ foo.add -- last message to append or last data to compress
+ foo.dict -- dictionary of the last 32K of data for next compression
+ foo.temp -- temporary dictionary file for compression after this one
+ foo.lock -- lock file for reading and writing the other files
+ foo.repairs -- log file for log file recovery operations (not compressed)
+
+ gzip file structure:
+ - fixed-length (no file name) header with extra field (see below)
+ - compressed data ending initially with empty stored block
+ - uncompressed data filling out originally empty stored block and
+ subsequent stored blocks as needed (16K max each)
+ - gzip trailer
+ - no junk at end (no other gzip streams)
+
+ When appending data, the information in the first three items above plus the
+ foo.add file are sufficient to recover an interrupted append operation. The
+ extra field has the necessary information to restore the start of the last
+ stored block and determine where to append the data in the foo.add file, as
+ well as the crc and length of the gzip data before the append operation.
+
+ The foo.add file is created before the gzip file is marked for append, and
+ deleted after the gzip file is marked as complete. So if the append
+ operation is interrupted, the data to add will still be there. If due to
+ some external force, the foo.add file gets deleted between when the append
+ operation was interrupted and when recovery is attempted, the gzip file will
+ still be restored, but without the appended data.
+
+ When compressing data, the information in the first two items above plus the
+ foo.add file are sufficient to recover an interrupted compress operation.
+ The extra field has the necessary information to find the end of the
+ compressed data, and contains both the crc and length of just the compressed
+ data and of the complete set of data including the contents of the foo.add
+ file.
+
+ Again, the foo.add file is maintained during the compress operation in case
+ of an interruption. If in the unlikely event the foo.add file with the data
+ to be compressed is missing due to some external force, a gzip file with
+ just the previous compressed data will be reconstructed. In this case, all
+ of the data that was to be compressed is lost (approximately one megabyte).
+ This will not occur if all that happened was an interruption of the compress
+ operation.
+
+ The third state that is marked is the replacement of the old dictionary with
+ the new dictionary after a compress operation. Once compression is
+ complete, the gzip file is marked as being in the replace state. This
+ completes the gzip file, so an interrupt after being so marked does not
+ result in recompression. Then the dictionary file is replaced, and the gzip
+ file is marked as completed. This state prevents the possibility of
+ restarting compression with the wrong dictionary file.
+
+ All three operations are wrapped by a lock/unlock procedure. In order to
+ gain exclusive access to the log files, first a foo.lock file must be
+ exclusively created. When all operations are complete, the lock is
+ released by deleting the foo.lock file. If when attempting to create the
+ lock file, it already exists and the modify time of the lock file is more
+ than five minutes old (set by the PATIENCE define below), then the old
+ lock file is considered stale and deleted, and the exclusive creation of
+ the lock file is retried. To assure that there are no false assessments
+ of the staleness of the lock file, the operations periodically touch the
+ lock file to update the modified date.
+
+ Following is the definition of the extra field with all of the information
+ required to enable the above append and compress operations and their
+ recovery if interrupted. Multi-byte values are stored little endian
+ (consistent with the gzip format). File pointers are eight bytes long.
+ The crc's and lengths for the gzip trailer are four bytes long. (Note that
+ the length at the end of a gzip file is used for error checking only, and
+ for large files is actually the length modulo 2^32.) The stored block
+ length is two bytes long. The gzip extra field two-byte identification is
+ "ap" for append. It is assumed that writing the extra field to the file is
+ an "atomic" operation. That is, either all of the extra field is written
+ to the file, or none of it is, if the operation is interrupted right at the
+ point of updating the extra field. This is a reasonable assumption, since
+ the extra field is within the first 52 bytes of the file, which is smaller
+ than any expected block size for a mass storage device (usually 512 bytes or
+ larger).
+
+ Extra field (35 bytes):
+ - Pointer to first stored block length -- this points to the two-byte length
+ of the first stored block, which is followed by the two-byte, one's
+ complement of that length. The stored block length is preceded by the
+ three-bit header of the stored block, which is the actual start of the
+ stored block in the deflate format. See the bit offset field below.
+ - Pointer to the last stored block length. This is the same as above, but
+ for the last stored block of the uncompressed data in the gzip file.
+ Initially this is the same as the first stored block length pointer.
+ When the stored block gets to 16K (see the MAX_STORE define), then a new
+ stored block as added, at which point the last stored block length pointer
+ is different from the first stored block length pointer. When they are
+ different, the first bit of the last stored block header is eight bits, or
+ one byte back from the block length.
+ - Compressed data crc and length. This is the crc and length of the data
+ that is in the compressed portion of the deflate stream. These are used
+ only in the event that the foo.add file containing the data to compress is
+ lost after a compress operation is interrupted.
+ - Total data crc and length. This is the crc and length of all of the data
+ stored in the gzip file, compressed and uncompressed. It is used to
+ reconstruct the gzip trailer when compressing, as well as when recovering
+ interrupted operations.
+ - Final stored block length. This is used to quickly find where to append,
+ and allows the restoration of the original final stored block state when
+ an append operation is interrupted.
+ - First stored block start as the number of bits back from the final stored
+ block first length byte. This value is in the range of 3..10, and is
+ stored as the low three bits of the final byte of the extra field after
+ subtracting three (0..7). This allows the last-block bit of the stored
+ block header to be updated when a new stored block is added, for the case
+ when the first stored block and the last stored block are the same. (When
+ they are different, the numbers of bits back is known to be eight.) This
+ also allows for new compressed data to be appended to the old compressed
+ data in the compress operation, overwriting the previous first stored
+ block, or for the compressed data to be terminated and a valid gzip file
+ reconstructed on the off chance that a compression operation was
+ interrupted and the data to compress in the foo.add file was deleted.
+ - The operation in process. This is the next two bits in the last byte (the
+ bits under the mask 0x18). The are interpreted as 0: nothing in process,
+ 1: append in process, 2: compress in process, 3: replace in process.
+ - The top three bits of the last byte in the extra field are reserved and
+ are currently set to zero.
+
+ Main procedure:
+ - Exclusively create the foo.lock file using the O_CREAT and O_EXCL modes of
+ the system open() call. If the modify time of an existing lock file is
+ more than PATIENCE seconds old, then the lock file is deleted and the
+ exclusive create is retried.
+ - Load the extra field from the foo.gz file, and see if an operation was in
+ progress but not completed. If so, apply the recovery procedure below.
+ - Perform the append procedure with the provided data.
+ - If the uncompressed data in the foo.gz file is 1MB or more, apply the
+ compress procedure.
+ - Delete the foo.lock file.
+
+ Append procedure:
+ - Put what to append in the foo.add file so that the operation can be
+ restarted if this procedure is interrupted.
+ - Mark the foo.gz extra field with the append operation in progress.
+ + Restore the original last-block bit and stored block length of the last
+ stored block from the information in the extra field, in case a previous
+ append operation was interrupted.
+ - Append the provided data to the last stored block, creating new stored
+ blocks as needed and updating the stored blocks last-block bits and
+ lengths.
+ - Update the crc and length with the new data, and write the gzip trailer.
+ - Write over the extra field (with a single write operation) with the new
+ pointers, lengths, and crc's, and mark the gzip file as not in process.
+ Though there is still a foo.add file, it will be ignored since nothing
+ is in process. If a foo.add file is leftover from a previously
+ completed operation, it is truncated when writing new data to it.
+ - Delete the foo.add file.
+
+ Compress and replace procedures:
+ - Read all of the uncompressed data in the stored blocks in foo.gz and write
+ it to foo.add. Also write foo.temp with the last 32K of that data to
+ provide a dictionary for the next invocation of this procedure.
+ - Rewrite the extra field marking foo.gz with a compression in process.
+ * If there is no data provided to compress (due to a missing foo.add file
+ when recovering), reconstruct and truncate the foo.gz file to contain
+ only the previous compressed data and proceed to the step after the next
+ one. Otherwise ...
+ - Compress the data with the dictionary in foo.dict, and write to the
+ foo.gz file starting at the bit immediately following the last previously
+ compressed block. If there is no foo.dict, proceed anyway with the
+ compression at slightly reduced efficiency. (For the foo.dict file to be
+ missing requires some external failure beyond simply the interruption of
+ a compress operation.) During this process, the foo.lock file is
+ periodically touched to assure that that file is not considered stale by
+ another process before we're done. The deflation is terminated with a
+ non-last empty static block (10 bits long), that is then located and
+ written over by a last-bit-set empty stored block.
+ - Append the crc and length of the data in the gzip file (previously
+ calculated during the append operations).
+ - Write over the extra field with the updated stored block offsets, bits
+ back, crc's, and lengths, and mark foo.gz as in process for a replacement
+ of the dictionary.
+ @ Delete the foo.add file.
+ - Replace foo.dict with foo.temp.
+ - Write over the extra field, marking foo.gz as complete.
+
+ Recovery procedure:
+ - If not a replace recovery, read in the foo.add file, and provide that data
+ to the appropriate recovery below. If there is no foo.add file, provide
+ a zero data length to the recovery. In that case, the append recovery
+ restores the foo.gz to the previous compressed + uncompressed data state.
+ For the the compress recovery, a missing foo.add file results in foo.gz
+ being restored to the previous compressed-only data state.
+ - Append recovery:
+ - Pick up append at + step above
+ - Compress recovery:
+ - Pick up compress at * step above
+ - Replace recovery:
+ - Pick up compress at @ step above
+ - Log the repair with a date stamp in foo.repairs

+We often get questions about how the <tt>deflate()</tt> and <tt>inflate()</tt> functions should be used.
+Users wonder when they should provide more input, when they should use more output,
+what to do with a <tt>Z_BUF_ERROR</tt>, how to make sure the process terminates properly, and
+so on. So for those who have read <tt>zlib.h</tt> (a few times), and
+would like further edification, below is an annotated example in C of simple routines to compress and decompress
+from an input file to an output file using <tt>deflate()</tt> and <tt>inflate()</tt> respectively. The
+annotations are interspersed between lines of the code. So please read between the lines.
+We hope this helps explain some of the intricacies of <em>zlib</em>.

+The first thing we do is to initialize the <em>zlib</em> state for compression using
+<tt>deflateInit()</tt>. This must be done before the first use of <tt>deflate()</tt>.
+The <tt>zalloc</tt>, <tt>zfree</tt>, and <tt>opaque</tt> fields in the <tt>strm</tt>
+structure must be initialized before calling <tt>deflateInit()</tt>. Here they are
+set to the <em>zlib</em> constant <tt>Z_NULL</tt> to request that <em>zlib</em> use
+the default memory allocation routines. An application may also choose to provide
+custom memory allocation routines here. <tt>deflateInit()</tt> will allocate on the
+order of 256K bytes for the internal state.
+(See <a href="zlib_tech.html"><em>zlib Technical Details</em></a>.)
+<p>
+<tt>deflateInit()</tt> is called with a pointer to the structure to be initialized and
+the compression level, which is an integer in the range of -1 to 9. Lower compression
+levels result in faster execution, but less compression. Higher levels result in
+greater compression, but slower execution. The <em>zlib</em> constant Z_DEFAULT_COMPRESSION,
+equal to -1,
+provides a good compromise between compression and speed and is equivalent to level 6.
+Level 0 actually does no compression at all, and in fact expands the data slightly to produce
+the <em>zlib</em> format (it is not a byte-for-byte copy of the input).
+More advanced applications of <em>zlib</em>
+may use <tt>deflateInit2()</tt> here instead. Such an application may want to reduce how
+much memory will be used, at some price in compression. Or it may need to request a
+<em>gzip</em> header and trailer instead of a <em>zlib</em> header and trailer, or raw
+encoding with no header or trailer at all.
+<p>
+We must check the return value of <tt>deflateInit()</tt> against the <em>zlib</em> constant
+<tt>Z_OK</tt> to make sure that it was able to
+allocate memory for the internal state, and that the provided arguments were valid.
+<tt>deflateInit()</tt> will also check that the version of <em>zlib</em> that the <tt>zlib.h</tt>
+file came from matches the version of <em>zlib</em> actually linked with the program. This
+is especially important for environments in which <em>zlib</em> is a shared library.
+<p>
+Note that an application can initialize multiple, independent <em>zlib</em> streams, which can
+operate in parallel. The state information maintained in the structure allows the <em>zlib</em>
+routines to be reentrant.

+With the pleasantries out of the way, now we can get down to business. The outer <tt>do</tt>-loop
+reads all of the input file and exits at the bottom of the loop once end-of-file is reached.
+This loop contains the only call of <tt>deflate()</tt>. So we must make sure that all of the
+input data has been processed and that all of the output data has been generated and consumed
+before we fall out of the loop at the bottom.
+<pre><b>
+ /* compress until end of file */
+ do {
+</b></pre>
+We start off by reading data from the input file. The number of bytes read is put directly
+into <tt>avail_in</tt>, and a pointer to those bytes is put into <tt>next_in</tt>. We also
+check to see if end-of-file on the input has been reached. If we are at the end of file, then <tt>flush</tt> is set to the
+<em>zlib</em> constant <tt>Z_FINISH</tt>, which is later passed to <tt>deflate()</tt> to
+indicate that this is the last chunk of input data to compress. We need to use <tt>feof()</tt>
+to check for end-of-file as opposed to seeing if fewer than <tt>CHUNK</tt> bytes have been read. The
+reason is that if the input file length is an exact multiple of <tt>CHUNK</tt>, we will miss
+the fact that we got to the end-of-file, and not know to tell <tt>deflate()</tt> to finish
+up the compressed stream. If we are not yet at the end of the input, then the <em>zlib</em>
+constant <tt>Z_NO_FLUSH</tt> will be passed to <tt>deflate</tt> to indicate that we are still
+in the middle of the uncompressed data.
+<p>
+If there is an error in reading from the input file, the process is aborted with
+<tt>deflateEnd()</tt> being called to free the allocated <em>zlib</em> state before returning
+the error. We wouldn't want a memory leak, now would we? <tt>deflateEnd()</tt> can be called
+at any time after the state has been initialized. Once that's done, <tt>deflateInit()</tt> (or
+<tt>deflateInit2()</tt>) would have to be called to start a new compression process. There is
+no point here in checking the <tt>deflateEnd()</tt> return code. The deallocation can't fail.
+<pre><b>
+ strm.avail_in = fread(in, 1, CHUNK, source);
+ if (ferror(source)) {
+ (void)deflateEnd(&strm);
+ return Z_ERRNO;
+ }
+ flush = feof(source) ? Z_FINISH : Z_NO_FLUSH;
+ strm.next_in = in;
+</b></pre><!-- -->
+The inner <tt>do</tt>-loop passes our chunk of input data to <tt>deflate()</tt>, and then
+keeps calling <tt>deflate()</tt> until it is done producing output. Once there is no more
+new output, <tt>deflate()</tt> is guaranteed to have consumed all of the input, i.e.,
+<tt>avail_in</tt> will be zero.
+<pre><b>
+ /* run deflate() on input until output buffer not full, finish
+ compression if all of source has been read in */
+ do {
+</b></pre>
+Output space is provided to <tt>deflate()</tt> by setting <tt>avail_out</tt> to the number
+of available output bytes and <tt>next_out</tt> to a pointer to that space.
+<pre><b>
+ strm.avail_out = CHUNK;
+ strm.next_out = out;
+</b></pre>
+Now we call the compression engine itself, <tt>deflate()</tt>. It takes as many of the
+<tt>avail_in</tt> bytes at <tt>next_in</tt> as it can process, and writes as many as
+<tt>avail_out</tt> bytes to <tt>next_out</tt>. Those counters and pointers are then
+updated past the input data consumed and the output data written. It is the amount of
+output space available that may limit how much input is consumed.
+Hence the inner loop to make sure that
+all of the input is consumed by providing more output space each time. Since <tt>avail_in</tt>
+and <tt>next_in</tt> are updated by <tt>deflate()</tt>, we don't have to mess with those
+between <tt>deflate()</tt> calls until it's all used up.
+<p>
+The parameters to <tt>deflate()</tt> are a pointer to the <tt>strm</tt> structure containing
+the input and output information and the internal compression engine state, and a parameter
+indicating whether and how to flush data to the output. Normally <tt>deflate</tt> will consume
+several K bytes of input data before producing any output (except for the header), in order
+to accumulate statistics on the data for optimum compression. It will then put out a burst of
+compressed data, and proceed to consume more input before the next burst. Eventually,
+<tt>deflate()</tt>
+must be told to terminate the stream, complete the compression with provided input data, and
+write out the trailer check value. <tt>deflate()</tt> will continue to compress normally as long
+as the flush parameter is <tt>Z_NO_FLUSH</tt>. Once the <tt>Z_FINISH</tt> parameter is provided,
+<tt>deflate()</tt> will begin to complete the compressed output stream. However depending on how
+much output space is provided, <tt>deflate()</tt> may have to be called several times until it
+has provided the complete compressed stream, even after it has consumed all of the input. The flush
+parameter must continue to be <tt>Z_FINISH</tt> for those subsequent calls.
+<p>
+There are other values of the flush parameter that are used in more advanced applications. You can
+force <tt>deflate()</tt> to produce a burst of output that encodes all of the input data provided
+so far, even if it wouldn't have otherwise, for example to control data latency on a link with
+compressed data. You can also ask that <tt>deflate()</tt> do that as well as erase any history up to
+that point so that what follows can be decompressed independently, for example for random access
+applications. Both requests will degrade compression by an amount depending on how often such
+requests are made.
+<p>
+<tt>deflate()</tt> has a return value that can indicate errors, yet we do not check it here. Why
+not? Well, it turns out that <tt>deflate()</tt> can do no wrong here. Let's go through
+<tt>deflate()</tt>'s return values and dispense with them one by one. The possible values are
+<tt>Z_OK</tt>, <tt>Z_STREAM_END</tt>, <tt>Z_STREAM_ERROR</tt>, or <tt>Z_BUF_ERROR</tt>. <tt>Z_OK</tt>
+is, well, ok. <tt>Z_STREAM_END</tt> is also ok and will be returned for the last call of
+<tt>deflate()</tt>. This is already guaranteed by calling <tt>deflate()</tt> with <tt>Z_FINISH</tt>
+until it has no more output. <tt>Z_STREAM_ERROR</tt> is only possible if the stream is not
+initialized properly, but we did initialize it properly. There is no harm in checking for
+<tt>Z_STREAM_ERROR</tt> here, for example to check for the possibility that some
+other part of the application inadvertently clobbered the memory containing the <em>zlib</em> state.
+<tt>Z_BUF_ERROR</tt> will be explained further below, but
+suffice it to say that this is simply an indication that <tt>deflate()</tt> could not consume
+more input or produce more output. <tt>deflate()</tt> can be called again with more output space
+or more available input, which it will be in this code.
+<pre><b>
+ ret = deflate(&strm, flush); /* no bad return value */
+ assert(ret != Z_STREAM_ERROR); /* state not clobbered */
+</b></pre>
+Now we compute how much output <tt>deflate()</tt> provided on the last call, which is the
+difference between how much space was provided before the call, and how much output space
+is still available after the call. Then that data, if any, is written to the output file.
+We can then reuse the output buffer for the next call of <tt>deflate()</tt>. Again if there
+is a file i/o error, we call <tt>deflateEnd()</tt> before returning to avoid a memory leak.
+<pre><b>
+ have = CHUNK - strm.avail_out;
+ if (fwrite(out, 1, have, dest) != have || ferror(dest)) {
+ (void)deflateEnd(&strm);
+ return Z_ERRNO;
+ }
+</b></pre>
+The inner <tt>do</tt>-loop is repeated until the last <tt>deflate()</tt> call fails to fill the
+provided output buffer. Then we know that <tt>deflate()</tt> has done as much as it can with
+the provided input, and that all of that input has been consumed. We can then fall out of this
+loop and reuse the input buffer.
+<p>
+The way we tell that <tt>deflate()</tt> has no more output is by seeing that it did not fill
+the output buffer, leaving <tt>avail_out</tt> greater than zero. However suppose that
+<tt>deflate()</tt> has no more output, but just so happened to exactly fill the output buffer!
+<tt>avail_out</tt> is zero, and we can't tell that <tt>deflate()</tt> has done all it can.
+As far as we know, <tt>deflate()</tt>
+has more output for us. So we call it again. But now <tt>deflate()</tt> produces no output
+at all, and <tt>avail_out</tt> remains unchanged as <tt>CHUNK</tt>. That <tt>deflate()</tt> call
+wasn't able to do anything, either consume input or produce output, and so it returns
+<tt>Z_BUF_ERROR</tt>. (See, I told you I'd cover this later.) However this is not a problem at
+all. Now we finally have the desired indication that <tt>deflate()</tt> is really done,
+and so we drop out of the inner loop to provide more input to <tt>deflate()</tt>.
+<p>
+With <tt>flush</tt> set to <tt>Z_FINISH</tt>, this final set of <tt>deflate()</tt> calls will
+complete the output stream. Once that is done, subsequent calls of <tt>deflate()</tt> would return
+<tt>Z_STREAM_ERROR</tt> if the flush parameter is not <tt>Z_FINISH</tt>, and do no more processing
+until the state is reinitialized.
+<p>
+Some applications of <em>zlib</em> have two loops that call <tt>deflate()</tt>
+instead of the single inner loop we have here. The first loop would call
+without flushing and feed all of the data to <tt>deflate()</tt>. The second loop would call
+<tt>deflate()</tt> with no more
+data and the <tt>Z_FINISH</tt> parameter to complete the process. As you can see from this
+example, that can be avoided by simply keeping track of the current flush state.
+<pre><b>
+ } while (strm.avail_out == 0);
+ assert(strm.avail_in == 0); /* all input will be used */
+</b></pre><!-- -->
+Now we check to see if we have already processed all of the input file. That information was
+saved in the <tt>flush</tt> variable, so we see if that was set to <tt>Z_FINISH</tt>. If so,
+then we're done and we fall out of the outer loop. We're guaranteed to get <tt>Z_STREAM_END</tt>
+from the last <tt>deflate()</tt> call, since we ran it until the last chunk of input was
+consumed and all of the output was generated.
+<pre><b>
+ /* done when last data in file processed */
+ } while (flush != Z_FINISH);
+ assert(ret == Z_STREAM_END); /* stream will be complete */
+</b></pre><!-- -->
+The process is complete, but we still need to deallocate the state to avoid a memory leak
+(or rather more like a memory hemorrhage if you didn't do this). Then
+finally we can return with a happy return value.
+<pre><b>
+ /* clean up and return */
+ (void)deflateEnd(&strm);
+ return Z_OK;
+}
+</b></pre><!-- -->
+Now we do the same thing for decompression in the <tt>inf()</tt> routine. <tt>inf()</tt>
+decompresses what is hopefully a valid <em>zlib</em> stream from the input file and writes the
+uncompressed data to the output file. Much of the discussion above for <tt>def()</tt>
+applies to <tt>inf()</tt> as well, so the discussion here will focus on the differences between
+the two.
+<pre><b>
+/* Decompress from file source to file dest until stream ends or EOF.
+ inf() returns Z_OK on success, Z_MEM_ERROR if memory could not be
+ allocated for processing, Z_DATA_ERROR if the deflate data is
+ invalid or incomplete, Z_VERSION_ERROR if the version of zlib.h and
+ the version of the library linked do not match, or Z_ERRNO if there
+ is an error reading or writing the files. */
+int inf(FILE *source, FILE *dest)
+{
+</b></pre>
+The local variables have the same functionality as they do for <tt>def()</tt>. The
+only difference is that there is no <tt>flush</tt> variable, since <tt>inflate()</tt>
+can tell from the <em>zlib</em> stream itself when the stream is complete.
+<pre><b>
+ int ret;
+ unsigned have;
+ z_stream strm;
+ unsigned char in[CHUNK];
+ unsigned char out[CHUNK];
+</b></pre><!-- -->
+The initialization of the state is the same, except that there is no compression level,
+of course, and two more elements of the structure are initialized. <tt>avail_in</tt>
+and <tt>next_in</tt> must be initialized before calling <tt>inflateInit()</tt>. This
+is because the application has the option to provide the start of the zlib stream in
+order for <tt>inflateInit()</tt> to have access to information about the compression
+method to aid in memory allocation. In the current implementation of <em>zlib</em>
+(up through versions 1.2.x), the method-dependent memory allocations are deferred to the first call of
+<tt>inflate()</tt> anyway. However those fields must be initialized since later versions
+of <em>zlib</em> that provide more compression methods may take advantage of this interface.
+In any case, no decompression is performed by <tt>inflateInit()</tt>, so the
+<tt>avail_out</tt> and <tt>next_out</tt> fields do not need to be initialized before calling.
+<p>
+Here <tt>avail_in</tt> is set to zero and <tt>next_in</tt> is set to <tt>Z_NULL</tt> to
+indicate that no input data is being provided.

+ if (ret != Z_OK)
+ return ret;
+</b></pre><!-- -->
+The outer <tt>do</tt>-loop decompresses input until <tt>inflate()</tt> indicates
+that it has reached the end of the compressed data and has produced all of the uncompressed
+output. This is in contrast to <tt>def()</tt> which processes all of the input file.
+If end-of-file is reached before the compressed data self-terminates, then the compressed
+data is incomplete and an error is returned.
+<pre><b>
+ /* decompress until deflate stream ends or end of file */

+We read input data and set the <tt>strm</tt> structure accordingly. If we've reached the

+compressed data is incomplete. Note that we may read more data than is eventually consumed
+by <tt>inflate()</tt>, if the input file continues past the <em>zlib</em> stream.
+For applications where <em>zlib</em> streams are embedded in other data, this routine would
+need to be modified to return the unused data, or at least indicate how much of the input
+data was not used, so the application would know where to pick up after the <em>zlib</em> stream.

+</b></pre>
+Now we run the decompression engine itself. There is no need to adjust the flush parameter, since
+the <em>zlib</em> format is self-terminating. The main difference here is that there are
+return values that we need to pay attention to. <tt>Z_DATA_ERROR</tt>
+indicates that <tt>inflate()</tt> detected an error in the <em>zlib</em> compressed data format,
+which means that either the data is not a <em>zlib</em> stream to begin with, or that the data was
+corrupted somewhere along the way since it was compressed. The other error to be processed is
+<tt>Z_MEM_ERROR</tt>, which can occur since memory allocation is deferred until <tt>inflate()</tt>
+needs it, unlike <tt>deflate()</tt>, whose memory is allocated at the start by <tt>deflateInit()</tt>.
+<p>
+Advanced applications may use
+<tt>deflateSetDictionary()</tt> to prime <tt>deflate()</tt> with a set of likely data to improve the
+first 32K or so of compression. This is noted in the <em>zlib</em> header, so <tt>inflate()</tt>
+requests that that dictionary be provided before it can start to decompress. Without the dictionary,
+correct decompression is not possible. For this routine, we have no idea what the dictionary is,
+so the <tt>Z_NEED_DICT</tt> indication is converted to a <tt>Z_DATA_ERROR</tt>.
+<p>
+<tt>inflate()</tt> can also return <tt>Z_STREAM_ERROR</tt>, which should not be possible here,
+but could be checked for as noted above for <tt>def()</tt>. <tt>Z_BUF_ERROR</tt> does not need to be
+checked for here, for the same reasons noted for <tt>def()</tt>. <tt>Z_STREAM_END</tt> will be

+ Version 1.0 29 May 2005 Mark Adler */
+
+/* Illustrate the use of Z_BLOCK, inflatePrime(), and inflateSetDictionary()
+ for random access of a compressed file. A file containing a zlib or gzip
+ stream is provided on the command line. The compressed stream is decoded in
+ its entirety, and an index built with access points about every SPAN bytes
+ in the uncompressed output. The compressed file is left open, and can then
+ be read randomly, having to decompress on the average SPAN/2 uncompressed
+ bytes before getting to the desired block of data.
+
+ An access point can be created at the start of any deflate block, by saving
+ the starting file offset and bit of that block, and the 32K bytes of
+ uncompressed data that precede that block. Also the uncompressed offset of
+ that block is saved to provide a referece for locating a desired starting
+ point in the uncompressed stream. build_index() works by decompressing the
+ input zlib or gzip stream a block at a time, and at the end of each block
+ deciding if enough uncompressed data has gone by to justify the creation of
+ a new access point. If so, that point is saved in a data structure that
+ grows as needed to accommodate the points.
+
+ To use the index, an offset in the uncompressed data is provided, for which
+ the latest accees point at or preceding that offset is located in the index.
+ The input file is positioned to the specified location in the index, and if
+ necessary the first few bits of the compressed data is read from the file.
+ inflate is initialized with those bits and the 32K of uncompressed data, and
+ the decompression then proceeds until the desired offset in the file is
+ reached. Then the decompression continues to read the desired uncompressed
+ data from the file.
+
+ Another approach would be to generate the index on demand. In that case,
+ requests for random access reads from the compressed data would try to use
+ the index, but if a read far enough past the end of the index is required,
+ then further index entries would be generated and added.
+
+ There is some fair bit of overhead to starting inflation for the random
+ access, mainly copying the 32K byte dictionary. So if small pieces of the
+ file are being accessed, it would make sense to implement a cache to hold
+ some lookahead and avoid many calls to extract() for small lengths.
+
+ Another way to build an index would be to use inflateCopy(). That would
+ not be constrained to have access points at block boundaries, but requires
+ more memory per access point, and also cannot be saved to file due to the
+ use of pointers in the state. The approach here allows for storage of the
+ index in a file.

+ strm provides the memory allocation functions and window buffer on input,
+ and provides information on the unused input on return. For Z_DATA_ERROR
+ returns, strm will also provide an error message.
+
+ in() and out() are the call-back input and output functions. When
+ inflateBack() needs more input, it calls in(). When inflateBack() has
+ filled the window with output, or when it completes with data in the
+ window, it calls out() to write out the data. The application must not
+ change the provided input until in() is called again or inflateBack()
+ returns. The application must not change the window/output buffer until
+ inflateBack() returns.
+
+ in() and out() are called with a descriptor parameter provided in the
+ inflateBack() call. This parameter can be a structure that provides the
+ information required to do the read or write, as well as accumulated
+ information on the input and output such as totals and check values.
+
+ in() should return zero on failure. out() should return non-zero on
+ failure. If either in() or out() fails, than inflateBack() returns a
+ Z_BUF_ERROR. strm->next_in can be checked for Z_NULL to see whether it
+ was in() or out() that caused in the error. Otherwise, inflateBack()
+ returns Z_STREAM_END on success, Z_DATA_ERROR for an deflate format
+ error, or Z_MEM_ERROR if it could not allocate memory for the state.
+ inflateBack() can also return Z_STREAM_ERROR if the input parameters
+ are not correct, i.e. strm is Z_NULL or the state was not initialized.

+ Decode literal, length, and distance codes and write out the resulting
+ literal and match bytes until either not enough input or output is
+ available, an end-of-block is encountered, or a data error is encountered.
+ When large enough input and output buffers are supplied to inflate(), for
+ example, a 16K input buffer and a 64K output buffer, more than 95% of the
+ inflate execution time is spent in this routine.
+
+ Entry assumptions:
+
+ state->mode == LEN
+ strm->avail_in >= 6
+ strm->avail_out >= 258
+ start >= strm->avail_out
+ state->bits < 8
+
+ On return, state->mode is one of:
+
+ LEN -- ran out of enough output space or enough available input
+ TYPE -- reached end of block code, inflate() to interpret next block
+ BAD -- error in block data
+
+ Notes:
+
+ - The maximum input bits used by a length/distance pair is 15 bits for the
+ length code, 5 bits for the length extra, 15 bits for the distance code,
+ and 13 bits for the distance extra. This totals 48 bits, or six bytes.
+ Therefore if strm->avail_in >= 6, then there is enough input to avoid
+ checking for available input while decoding.
+
+ - The maximum bytes that a single length/distance pair can output is 258
+ bytes, which is the maximum length that can be coded. inflate_fast()
+ requires strm->avail_out >= 258 for each loop to avoid checking for
+ output space.

+ * Copyright (C) 1995-2011 Mark Adler
+ * For conditions of distribution and use, see copyright notice in zlib.h
+ */
+
+/*
+ * Change history:
+ *
+ * 1.2.beta0 24 Nov 2002
+ * - First version -- complete rewrite of inflate to simplify code, avoid
+ * creation of window when not needed, minimize use of window when it is
+ * needed, make inffast.c even faster, implement gzip decoding, and to
+ * improve code readability and style over the previous zlib inflate code
+ *
+ * 1.2.beta1 25 Nov 2002
+ * - Use pointers for available input and output checking in inffast.c
+ * - Remove input and output counters in inffast.c
+ * - Change inffast.c entry and loop from avail_in >= 7 to >= 6
+ * - Remove unnecessary second byte pull from length extra in inffast.c
+ * - Unroll direct copy to three copies per loop in inffast.c
+ *
+ * 1.2.beta2 4 Dec 2002
+ * - Change external routine names to reduce potential conflicts
+ * - Correct filename to inffixed.h for fixed tables in inflate.c
+ * - Make hbuf[] unsigned char to match parameter type in inflate.c
+ * - Change strm->next_out[-state->offset] to *(strm->next_out - state->offset)
+ * to avoid negation problem on Alphas (64 bit) in inflate.c
+ *
+ * 1.2.beta3 22 Dec 2002
+ * - Add comments on state->bits assertion in inffast.c
+ * - Add comments on op field in inftrees.h
+ * - Fix bug in reuse of allocated window after inflateReset()
+ * - Remove bit fields--back to byte structure for speed
+ * - Remove distance extra == 0 check in inflate_fast()--only helps for lengths
+ * - Change post-increments to pre-increments in inflate_fast(), PPC biased?
+ * - Add compile time option, POSTINC, to use post-increments instead (Intel?)
+ * - Make MATCH copy in inflate() much faster for when inflate_fast() not used
+ * - Use local copies of stream next and avail values, as well as local bit
+ * buffer and bit count in inflate()--for speed when inflate_fast() not used
+ *
+ * 1.2.beta4 1 Jan 2003
+ * - Split ptr - 257 statements in inflate_table() to avoid compiler warnings
+ * - Move a comment on output buffer sizes from inffast.c to inflate.c
+ * - Add comments in inffast.c to introduce the inflate_fast() routine
+ * - Rearrange window copies in inflate_fast() for speed and simplification
+ * - Unroll last copy for window match in inflate_fast()
+ * - Use local copies of window variables in inflate_fast() for speed
+ * - Pull out common wnext == 0 case for speed in inflate_fast()
+ * - Make op and len in inflate_fast() unsigned for consistency
+ * - Add FAR to lcode and dcode declarations in inflate_fast()
+ * - Simplified bad distance check in inflate_fast()
+ * - Added inflateBackInit(), inflateBack(), and inflateBackEnd() in new
+ * source file infback.c to provide a call-back interface to inflate for
+ * programs like gzip and unzip -- uses window as output buffer to avoid
+ * window copying
+ *
+ * 1.2.beta5 1 Jan 2003
+ * - Improved inflateBack() interface to allow the caller to provide initial
+ * input in strm.
+ * - Fixed stored blocks bug in inflateBack()
+ *
+ * 1.2.beta6 4 Jan 2003
+ * - Added comments in inffast.c on effectiveness of POSTINC
+ * - Typecasting all around to reduce compiler warnings
+ * - Changed loops from while (1) or do {} while (1) to for (;;), again to
+ * make compilers happy
+ * - Changed type of window in inflateBackInit() to unsigned char *
+ *
+ * 1.2.beta7 27 Jan 2003
+ * - Changed many types to unsigned or unsigned short to avoid warnings
+ * - Added inflateCopy() function
+ *
+ * 1.2.0 9 Mar 2003
+ * - Changed inflateBack() interface to provide separate opaque descriptors
+ * for the in() and out() functions
+ * - Changed inflateBack() argument and in_func typedef to swap the length
+ * and buffer address return values for the input function
+ * - Check next_in and next_out for Z_NULL on entry to inflate()
+ *
+ * The history for versions after 1.2.0 are in ChangeLog in zlib distribution.

+ inflate() uses a state machine to process as much input data and generate as
+ much output data as possible before returning. The state machine is
+ structured roughly as follows:
+
+ for (;;) switch (state) {
+ ...
+ case STATEn:
+ if (not enough input data or output space to make progress)
+ return;
+ ... make progress ...
+ state = STATEm;
+ break;
+ ...
+ }
+
+ so when inflate() is called again, the same case is attempted again, and
+ if the appropriate resources are provided, the machine proceeds to the
+ next state. The NEEDBITS() macro is usually the way the state evaluates
+ whether it can proceed or should return. NEEDBITS() does the return if
+ the requested bits are not available. The typical use of the BITS macros
+ is:
+
+ NEEDBITS(n);
+ ... do something with BITS(n) ...
+ DROPBITS(n);
+
+ where NEEDBITS(n) either returns from inflate() if there isn't enough
+ input left to load n bits into the accumulator, or it continues. BITS(n)
+ gives the low n bits in the accumulator. When done, DROPBITS(n) drops
+ the low n bits off the accumulator. INITBITS() clears the accumulator
+ and sets the number of available bits to zero. BYTEBITS() discards just
+ enough bits to put the accumulator on a byte boundary. After BYTEBITS()
+ and a NEEDBITS(8), then BITS(8) would return the next byte in the stream.
+
+ NEEDBITS(n) uses PULLBYTE() to get an available byte of input, or to return
+ if there is no input available. The decoding of variable length codes uses
+ PULLBYTE() directly in order to pull just enough bytes to decode the next
+ code, and no more.
+
+ Some states loop until they get enough input, making sure that enough
+ state information is maintained to continue the loop where it left off
+ if NEEDBITS() returns in the loop. For example, want, need, and keep
+ would all have to actually be part of the saved state in case NEEDBITS()
+ returns:
+
+ case STATEw:
+ while (want < need) {
+ NEEDBITS(n);
+ keep[want++] = BITS(n);
+ DROPBITS(n);
+ }
+ state = STATEx;
+ case STATEx:
+
+ As shown above, if the next state is also the next case, then the break
+ is omitted.
+
+ A state may also return if there is not enough output space available to
+ complete that state. Those states are copying stored data, writing a
+ literal byte, and copying a matching string.
+
+ When returning, a "goto inf_leave" is used to update the total counters,
+ update the check value, and determine whether any progress has been made
+ during that inflate() call in order to return the proper return code.
+ Progress is defined as a change in either strm->avail_in or strm->avail_out.
+ When there is a window, goto inf_leave will update the window with the last
+ output written. If a goto inf_leave occurs in the middle of decompression
+ and there is no window currently, goto inf_leave will create one and copy
+ output to the window for the next call of inflate().
+
+ In this implementation, the flush parameter of inflate() only affects the
+ return code (per zlib.h). inflate() always writes as much as possible to
+ strm->next_out, given the space available and the provided input--the effect
+ documented in zlib.h of Z_SYNC_FLUSH. Furthermore, inflate() always defers
+ the allocation of and copying into a sliding window until necessary, which
+ provides the effect documented in zlib.h for Z_FINISH when the entire input
+ stream available. So the only thing the flush parameter actually does is:
+ when flush is set to Z_FINISH, inflate() cannot return Z_OK. Instead it
+ will return Z_BUF_ERROR if it has not reached the end of the stream.

+ for codes with equal lengths. Then the code starts with all zero bits
+ for the first code of the shortest length, and the codes are integer
+ increments for the same length, and zeros are appended as the length
+ increases. For the deflate format, these bits are stored backwards
+ from their more natural integer increment ordering, and so when the

+ are incremented backwards.
+
+ This routine assumes, but does not check, that all of the entries in
+ lens[] are in the range 0..MAXBITS. The caller must assure this.
+ 1..MAXBITS is interpreted as that code length. zero means that that
+ symbol does not occur in this code.
+

+ creating from that a table of starting indices for each length in the
+ sorted table, and then entering the symbols in order in the sorted
+ table. The sorted table is work[], with that space being provided by
+ the caller.
+

+See below some functions declarations for Visual Basic.
+
+Frequently Asked Question:
+
+Q: Each time I use the compress function I get the -5 error (not enough
+ room in the output buffer).
+
+A: Make sure that the length of the compressed buffer is passed by
+ reference ("as any"), not by value ("as long"). Also check that
+ before the call of compress this length is equal to the total size of
+ the compressed buffer and not zero.

+ These memory tracking routines are provided to zlib and track all of zlib's
+ allocations and deallocations, check for LIFO operations, keep a current
+ and high water mark of total bytes requested, optionally set a limit on the
+ total memory that can be allocated, and when done check for memory leaks.
+
+ They are used as follows:
+
+ z_stream strm;
+ mem_setup(&strm) initializes the memory tracking and sets the
+ zalloc, zfree, and opaque members of strm to use
+ memory tracking for all zlib operations on strm
+ mem_limit(&strm, limit) sets a limit on the total bytes requested -- a
+ request that exceeds this limit will result in an
+ allocation failure (returns NULL) -- setting the
+ limit to zero means no limit, which is the default
+ after mem_setup()
+ mem_used(&strm, "msg") prints to stderr "msg" and the total bytes used
+ mem_high(&strm, "msg") prints to stderr "msg" and the high water mark
+ mem_done(&strm, "msg") ends memory tracking, releases all allocations
+ for the tracking as well as leaked zlib blocks, if
+ any. If there was anything unusual, such as leaked
+ blocks, non-FIFO frees, or frees of addresses not
+ allocated, then "msg" and information about the
+ problem is printed to stderr. If everything is
+ normal, nothing is printed. mem_done resets the
+ strm members to Z_NULL to use the default memory
+ allocation routines on the next zlib initialization
+ using strm.

+ * ALGORITHM
+ *
+ * The "deflation" process uses several Huffman trees. The more
+ * common source values are represented by shorter bit sequences.
+ *
+ * Each code tree is stored in a compressed form which is itself
+ * a Huffman encoding of the lengths of all the code strings (in
+ * ascending order by source values). The actual code strings are
+ * reconstructed from the lengths in the inflate process, as described
+ * in the deflate specification.

+
+ Frequently Asked Questions about ZLIB1.DLL
+
+
+This document describes the design, the rationale, and the usage
+of the official DLL build of zlib, named ZLIB1.DLL. If you have
+general questions about zlib, you should see the file "FAQ" found
+in the zlib distribution, or at the following location:
+ http://www.gzip.org/zlib/zlib_faq.html
+
+
+ 1. What is ZLIB1.DLL, and how can I get it?
+
+ - ZLIB1.DLL is the official build of zlib as a DLL.
+ (Please remark the character '1' in the name.)
+
+ Pointers to a precompiled ZLIB1.DLL can be found in the zlib
+ web site at:
+ http://www.zlib.net/
+
+ Applications that link to ZLIB1.DLL can rely on the following
+ specification:
+
+ * The exported symbols are exclusively defined in the source
+ files "zlib.h" and "zlib.def", found in an official zlib
+ source distribution.
+ * The symbols are exported by name, not by ordinal.
+ * The exported names are undecorated.
+ * The calling convention of functions is "C" (CDECL).
+ * The ZLIB1.DLL binary is linked to MSVCRT.DLL.
+
+ The archive in which ZLIB1.DLL is bundled contains compiled
+ test programs that must run with a valid build of ZLIB1.DLL.
+ It is recommended to download the prebuilt DLL from the zlib
+ web site, instead of building it yourself, to avoid potential
+ incompatibilities that could be introduced by your compiler
+ and build settings. If you do build the DLL yourself, please
+ make sure that it complies with all the above requirements,
+ and it runs with the precompiled test programs, bundled with
+ the original ZLIB1.DLL distribution.
+
+ If, for any reason, you need to build an incompatible DLL,
+ please use a different file name.
+
+
+ 2. Why did you change the name of the DLL to ZLIB1.DLL?
+ What happened to the old ZLIB.DLL?
+
+ - The old ZLIB.DLL, built from zlib-1.1.4 or earlier, required
+ compilation settings that were incompatible to those used by
+ a static build. The DLL settings were supposed to be enabled
+ by defining the macro ZLIB_DLL, before including "zlib.h".
+ Incorrect handling of this macro was silently accepted at
+ build time, resulting in two major problems:
+
+ * ZLIB_DLL was missing from the old makefile. When building
+ the DLL, not all people added it to the build options. In
+ consequence, incompatible incarnations of ZLIB.DLL started
+ to circulate around the net.
+
+ * When switching from using the static library to using the
+ DLL, applications had to define the ZLIB_DLL macro and
+ to recompile all the sources that contained calls to zlib
+ functions. Failure to do so resulted in creating binaries
+ that were unable to run with the official ZLIB.DLL build.
+
+ The only possible solution that we could foresee was to make
+ a binary-incompatible change in the DLL interface, in order to
+ remove the dependency on the ZLIB_DLL macro, and to release
+ the new DLL under a different name.
+
+ We chose the name ZLIB1.DLL, where '1' indicates the major
+ zlib version number. We hope that we will not have to break
+ the binary compatibility again, at least not as long as the
+ zlib-1.x series will last.
+
+ There is still a ZLIB_DLL macro, that can trigger a more
+ efficient build and use of the DLL, but compatibility no
+ longer dependents on it.
+
+
+ 3. Can I build ZLIB.DLL from the new zlib sources, and replace
+ an old ZLIB.DLL, that was built from zlib-1.1.4 or earlier?
+
+ - In principle, you can do it by assigning calling convention
+ keywords to the macros ZEXPORT and ZEXPORTVA. In practice,
+ it depends on what you mean by "an old ZLIB.DLL", because the
+ old DLL exists in several mutually-incompatible versions.
+ You have to find out first what kind of calling convention is
+ being used in your particular ZLIB.DLL build, and to use the
+ same one in the new build. If you don't know what this is all
+ about, you might be better off if you would just leave the old
+ DLL intact.
+
+
+ 4. Can I compile my application using the new zlib interface, and
+ link it to an old ZLIB.DLL, that was built from zlib-1.1.4 or
+ earlier?
+
+ - The official answer is "no"; the real answer depends again on
+ what kind of ZLIB.DLL you have. Even if you are lucky, this
+ course of action is unreliable.
+
+ If you rebuild your application and you intend to use a newer
+ version of zlib (post- 1.1.4), it is strongly recommended to
+ link it to the new ZLIB1.DLL.
+
+
+ 5. Why are the zlib symbols exported by name, and not by ordinal?
+
+ - Although exporting symbols by ordinal is a little faster, it
+ is risky. Any single glitch in the maintenance or use of the
+ DEF file that contains the ordinals can result in incompatible
+ builds and frustrating crashes. Simply put, the benefits of
+ exporting symbols by ordinal do not justify the risks.
+
+ Technically, it should be possible to maintain ordinals in
+ the DEF file, and still export the symbols by name. Ordinals
+ exist in every DLL, and even if the dynamic linking performed
+ at the DLL startup is searching for names, ordinals serve as
+ hints, for a faster name lookup. However, if the DEF file
+ contains ordinals, the Microsoft linker automatically builds
+ an implib that will cause the executables linked to it to use
+ those ordinals, and not the names. It is interesting to
+ notice that the GNU linker for Win32 does not suffer from this
+ problem.
+
+ It is possible to avoid the DEF file if the exported symbols
+ are accompanied by a "__declspec(dllexport)" attribute in the
+ source files. You can do this in zlib by predefining the
+ ZLIB_DLL macro.
+
+
+ 6. I see that the ZLIB1.DLL functions use the "C" (CDECL) calling
+ convention. Why not use the STDCALL convention?
+ STDCALL is the standard convention in Win32, and I need it in
+ my Visual Basic project!
+
+ (For readability, we use CDECL to refer to the convention
+ triggered by the "__cdecl" keyword, STDCALL to refer to
+ the convention triggered by "__stdcall", and FASTCALL to
+ refer to the convention triggered by "__fastcall".)
+
+ - Most of the native Windows API functions (without varargs) use
+ indeed the WINAPI convention (which translates to STDCALL in
+ Win32), but the standard C functions use CDECL. If a user
+ application is intrinsically tied to the Windows API (e.g.
+ it calls native Windows API functions such as CreateFile()),
+ sometimes it makes sense to decorate its own functions with
+ WINAPI. But if ANSI C or POSIX portability is a goal (e.g.
+ it calls standard C functions such as fopen()), it is not a
+ sound decision to request the inclusion of <windows.h>, or to
+ use non-ANSI constructs, for the sole purpose to make the user
+ functions STDCALL-able.
+
+ The functionality offered by zlib is not in the category of
+ "Windows functionality", but is more like "C functionality".
+
+ Technically, STDCALL is not bad; in fact, it is slightly
+ faster than CDECL, and it works with variable-argument
+ functions, just like CDECL. It is unfortunate that, in spite
+ of using STDCALL in the Windows API, it is not the default
+ convention used by the C compilers that run under Windows.
+ The roots of the problem reside deep inside the unsafety of
+ the K&R-style function prototypes, where the argument types
+ are not specified; but that is another story for another day.
+
+ The remaining fact is that CDECL is the default convention.
+ Even if an explicit convention is hard-coded into the function
+ prototypes inside C headers, problems may appear. The
+ necessity to expose the convention in users' callbacks is one
+ of these problems.
+
+ The calling convention issues are also important when using
+ zlib in other programming languages. Some of them, like Ada
+ (GNAT) and Fortran (GNU G77), have C bindings implemented
+ initially on Unix, and relying on the C calling convention.
+ On the other hand, the pre- .NET versions of Microsoft Visual
+ Basic require STDCALL, while Borland Delphi prefers, although
+ it does not require, FASTCALL.
+
+ In fairness to all possible uses of zlib outside the C
+ programming language, we choose the default "C" convention.
+ Anyone interested in different bindings or conventions is
+ encouraged to maintain specialized projects. The "contrib/"
+ directory from the zlib distribution already holds a couple
+ of foreign bindings, such as Ada, C++, and Delphi.
+
+
+ 7. I need a DLL for my Visual Basic project. What can I do?
+
+ - Define the ZLIB_WINAPI macro before including "zlib.h", when
+ building both the DLL and the user application (except that
+ you don't need to define anything when using the DLL in Visual
+ Basic). The ZLIB_WINAPI macro will switch on the WINAPI
+ (STDCALL) convention. The name of this DLL must be different
+ than the official ZLIB1.DLL.
+
+ Gilles Vollant has contributed a build named ZLIBWAPI.DLL,
+ with the ZLIB_WINAPI macro turned on, and with the minizip
+ functionality built in. For more information, please read
+ the notes inside "contrib/vstudio/readme.txt", found in the
+ zlib distribution.
+
+
+ 8. I need to use zlib in my Microsoft .NET project. What can I
+ do?
+
+ - Henrik Ravn has contributed a .NET wrapper around zlib. Look
+ into contrib/dotzlib/, inside the zlib distribution.
+
+
+ 9. If my application uses ZLIB1.DLL, should I link it to
+ MSVCRT.DLL? Why?
+
+ - It is not required, but it is recommended to link your
+ application to MSVCRT.DLL, if it uses ZLIB1.DLL.
+
+ The executables (.EXE, .DLL, etc.) that are involved in the
+ same process and are using the C run-time library (i.e. they
+ are calling standard C functions), must link to the same
+ library. There are several libraries in the Win32 system:
+ CRTDLL.DLL, MSVCRT.DLL, the static C libraries, etc.
+ Since ZLIB1.DLL is linked to MSVCRT.DLL, the executables that
+ depend on it should also be linked to MSVCRT.DLL.
+
+
+10. Why are you saying that ZLIB1.DLL and my application should
+ be linked to the same C run-time (CRT) library? I linked my
+ application and my DLLs to different C libraries (e.g. my
+ application to a static library, and my DLLs to MSVCRT.DLL),
+ and everything works fine.
+
+ - If a user library invokes only pure Win32 API (accessible via
+ <windows.h> and the related headers), its DLL build will work
+ in any context. But if this library invokes standard C API,
+ things get more complicated.
+
+ There is a single Win32 library in a Win32 system. Every
+ function in this library resides in a single DLL module, that
+ is safe to call from anywhere. On the other hand, there are
+ multiple versions of the C library, and each of them has its
+ own separate internal state. Standalone executables and user
+ DLLs that call standard C functions must link to a C run-time
+ (CRT) library, be it static or shared (DLL). Intermixing
+ occurs when an executable (not necessarily standalone) and a
+ DLL are linked to different CRTs, and both are running in the
+ same process.
+
+ Intermixing multiple CRTs is possible, as long as their
+ internal states are kept intact. The Microsoft Knowledge Base
+ articles KB94248 "HOWTO: Use the C Run-Time" and KB140584
+ "HOWTO: Link with the Correct C Run-Time (CRT) Library"
+ mention the potential problems raised by intermixing.
+
+ If intermixing works for you, it's because your application
+ and DLLs are avoiding the corruption of each of the CRTs'
+ internal states, maybe by careful design, or maybe by fortune.
+
+ Also note that linking ZLIB1.DLL to non-Microsoft CRTs, such
+ as those provided by Borland, raises similar problems.
+
+
+11. Why are you linking ZLIB1.DLL to MSVCRT.DLL?
+
+ - MSVCRT.DLL exists on every Windows 95 with a new service pack
+ installed, or with Microsoft Internet Explorer 4 or later, and
+ on all other Windows 4.x or later (Windows 98, Windows NT 4,
+ or later). It is freely distributable; if not present in the
+ system, it can be downloaded from Microsoft or from other
+ software provider for free.
+
+ The fact that MSVCRT.DLL does not exist on a virgin Windows 95
+ is not so problematic. Windows 95 is scarcely found nowadays,
+ Microsoft ended its support a long time ago, and many recent
+ applications from various vendors, including Microsoft, do not
+ even run on it. Furthermore, no serious user should run
+ Windows 95 without a proper update installed.
+
+
+12. Why are you not linking ZLIB1.DLL to
+ <<my favorite C run-time library>> ?
+
+ - We considered and abandoned the following alternatives:
+
+ * Linking ZLIB1.DLL to a static C library (LIBC.LIB, or
+ LIBCMT.LIB) is not a good option. People are using the DLL
+ mainly to save disk space. If you are linking your program
+ to a static C library, you may as well consider linking zlib
+ in statically, too.
+
+ * Linking ZLIB1.DLL to CRTDLL.DLL looks appealing, because
+ CRTDLL.DLL is present on every Win32 installation.
+ Unfortunately, it has a series of problems: it does not
+ work properly with Microsoft's C++ libraries, it does not
+ provide support for 64-bit file offsets, (and so on...),
+ and Microsoft discontinued its support a long time ago.
+
+ * Linking ZLIB1.DLL to MSVCR70.DLL or MSVCR71.DLL, supplied
+ with the Microsoft .NET platform, and Visual C++ 7.0/7.1,
+ raises problems related to the status of ZLIB1.DLL as a
+ system component. According to the Microsoft Knowledge Base
+ article KB326922 "INFO: Redistribution of the Shared C
+ Runtime Component in Visual C++ .NET", MSVCR70.DLL and
+ MSVCR71.DLL are not supposed to function as system DLLs,
+ because they may clash with MSVCRT.DLL. Instead, the
+ application's installer is supposed to put these DLLs
+ (if needed) in the application's private directory.
+ If ZLIB1.DLL depends on a non-system runtime, it cannot
+ function as a redistributable system component.
+
+ * Linking ZLIB1.DLL to non-Microsoft runtimes, such as
+ Borland's, or Cygwin's, raises problems related to the
+ reliable presence of these runtimes on Win32 systems.
+ It's easier to let the DLL build of zlib up to the people
+ who distribute these runtimes, and who may proceed as
+ explained in the answer to Question 14.
+
+
+13. If ZLIB1.DLL cannot be linked to MSVCR70.DLL or MSVCR71.DLL,
+ how can I build/use ZLIB1.DLL in Microsoft Visual C++ 7.0
+ (Visual Studio .NET) or newer?
+
+ - Due to the problems explained in the Microsoft Knowledge Base
+ article KB326922 (see the previous answer), the C runtime that
+ comes with the VC7 environment is no longer considered a
+ system component. That is, it should not be assumed that this
+ runtime exists, or may be installed in a system directory.
+ Since ZLIB1.DLL is supposed to be a system component, it may
+ not depend on a non-system component.
+
+ In order to link ZLIB1.DLL and your application to MSVCRT.DLL
+ in VC7, you need the library of Visual C++ 6.0 or older. If
+ you don't have this library at hand, it's probably best not to
+ use ZLIB1.DLL.
+
+ We are hoping that, in the future, Microsoft will provide a
+ way to build applications linked to a proper system runtime,
+ from the Visual C++ environment. Until then, you have a
+ couple of alternatives, such as linking zlib in statically.
+ If your application requires dynamic linking, you may proceed
+ as explained in the answer to Question 14.
+
+
+14. I need to link my own DLL build to a CRT different than
+ MSVCRT.DLL. What can I do?
+
+ - Feel free to rebuild the DLL from the zlib sources, and link
+ it the way you want. You should, however, clearly state that
+ your build is unofficial. You should give it a different file
+ name, and/or install it in a private directory that can be
+ accessed by your application only, and is not visible to the
+ others (i.e. it's neither in the PATH, nor in the SYSTEM or
+ SYSTEM32 directories). Otherwise, your build may clash with
+ applications that link to the official build.
+
+ For example, in Cygwin, zlib is linked to the Cygwin runtime
+ CYGWIN1.DLL, and it is distributed under the name CYGZ.DLL.
+
+
+15. May I include additional pieces of code that I find useful,
+ link them in ZLIB1.DLL, and export them?
+
+ - No. A legitimate build of ZLIB1.DLL must not include code
+ that does not originate from the official zlib source code.
+ But you can make your own private DLL build, under a different
+ file name, as suggested in the previous answer.
+
+ For example, zlib is a part of the VCL library, distributed
+ with Borland Delphi and C++ Builder. The DLL build of VCL
+ is a redistributable file, named VCLxx.DLL.
+
+
+16. May I remove some functionality out of ZLIB1.DLL, by enabling
+ macros like NO_GZCOMPRESS or NO_GZIP at compile time?
+
+ - No. A legitimate build of ZLIB1.DLL must provide the complete
+ zlib functionality, as implemented in the official zlib source
+ code. But you can make your own private DLL build, under a
+ different file name, as suggested in the previous answer.
+
+
+17. I made my own ZLIB1.DLL build. Can I test it for compliance?
+
+ - We prefer that you download the official DLL from the zlib
+ web site. If you need something peculiar from this DLL, you
+ can send your suggestion to the zlib mailing list.
+
+ However, in case you do rebuild the DLL yourself, you can run
+ it with the test programs found in the DLL distribution.
+ Running these test programs is not a guarantee of compliance,
+ but a failure can imply a detected problem.

+ZLIB DATA COMPRESSION LIBRARY
+
+zlib 1.2.4 is a general purpose data compression library. All the code is
+thread safe. The data format used by the zlib library is described by RFCs
+(Request for Comments) 1950 to 1952 in the files
+http://www.ietf.org/rfc/rfc1950.txt (zlib format), rfc1951.txt (deflate format)
+and rfc1952.txt (gzip format).
+
+All functions of the compression library are documented in the file zlib.h
+(volunteer to write man pages welcome, contact zlib@gzip.org). Two compiled
+examples are distributed in this package, example and minigzip. The example_d
+and minigzip_d flavors validate that the zlib1.dll file is working correctly.
+
+Questions about zlib should be sent to <zlib@gzip.org>. The zlib home page
+is http://zlib.net/ . Before reporting a problem, please check this site to
+verify that you have the latest version of zlib; otherwise get the latest
+version and check whether the problem still exists or not.
+
+PLEASE read DLL_FAQ.txt, and the the zlib FAQ http://zlib.net/zlib_faq.html
+before asking for help.
+
+
+Manifest:
+
+The package zlib-1.2.4-win32-x86.zip contains the following files:
+
+ README-WIN32.txt This document
+ ChangeLog Changes since previous zlib packages
+ DLL_FAQ.txt Frequently asked questions about zlib1.dll
+ zlib.3.pdf Documentation of this library in Adobe Acrobat format
+
+ example.exe A statically-bound example (using zlib.lib, not the dll)
+ example.pdb Symbolic information for debugging example.exe
+
+ example_d.exe A zlib1.dll bound example (using zdll.lib)
+ example_d.pdb Symbolic information for debugging example_d.exe
+
+ minigzip.exe A statically-bound test program (using zlib.lib, not the dll)
+ minigzip.pdb Symbolic information for debugging minigzip.exe
+
+ minigzip_d.exe A zlib1.dll bound test program (using zdll.lib)
+ minigzip_d.pdb Symbolic information for debugging minigzip_d.exe
+
+ zlib.h Install these files into the compilers' INCLUDE path to
+ zconf.h compile programs which use zlib.lib or zdll.lib
+
+ zdll.lib Install these files into the compilers' LIB path if linking
+ zdll.exp a compiled program to the zlib1.dll binary
+
+ zlib.lib Install these files into the compilers' LIB path to link zlib
+ zlib.pdb into compiled programs, without zlib1.dll runtime dependency
+ (zlib.pdb provides debugging info to the compile time linker)
+
+ zlib1.dll Install this binary shared library into the system PATH, or
+ the program's runtime directory (where the .exe resides)
+ zlib1.pdb Install in the same directory as zlib1.dll, in order to debug
+ an application crash using WinDbg or similar tools.
+
+All .pdb files above are entirely optional, but are very useful to a developer
+attempting to diagnose program misbehavior or a crash. Many additional
+important files for developers can be found in the zlib124.zip source package
+available from http://zlib.net/ - review that package's README file for details.
+
+
+Acknowledgments:
+
+The deflate format used by zlib was defined by Phil Katz. The deflate and
+zlib specifications were written by L. Peter Deutsch. Thanks to all the
+people who reported problems and suggested various improvements in zlib; they
+are too numerous to cite here.

+.TH ZLIB 3 "29 Jan 2012"
+.SH NAME
+zlib \- compression/decompression library
+.SH SYNOPSIS
+[see
+.I zlib.h
+for full description]
+.SH DESCRIPTION
+The
+.I zlib
+library is a general purpose data compression library.
+The code is thread safe, assuming that the standard library functions
+used are thread safe, such as memory allocation routines.
+It provides in-memory compression and decompression functions,
+including integrity checks of the uncompressed data.
+This version of the library supports only one compression method (deflation)
+but other algorithms may be added later
+with the same stream interface.
+.LP
+Compression can be done in a single step if the buffers are large enough
+or can be done by repeated calls of the compression function.
+In the latter case,
+the application must provide more input and/or consume the output
+(providing more output space) before each call.
+.LP
+The library also supports reading and writing files in
+.IR gzip (1)
+(.gz) format
+with an interface similar to that of stdio.
+.LP
+The library does not install any signal handler.
+The decoder checks the consistency of the compressed data,
+so the library should never crash even in the case of corrupted input.
+.LP
+All functions of the compression library are documented in the file
+.IR zlib.h .
+The distribution source includes examples of use of the library
+in the files
+.I test/example.c
+and
+.IR test/minigzip.c,
+as well as other examples in the
+.IR examples/
+directory.
+.LP
+Changes to this version are documented in the file
+.I ChangeLog
+that accompanies the source.
+.LP
+.I zlib
+is available in Java using the java.util.zip package:
+.IP
+http://java.sun.com/developer/technicalArticles/Programming/compression/
+.LP
+A Perl interface to
+.IR zlib ,
+written by Paul Marquess (pmqs@cpan.org),
+is available at CPAN (Comprehensive Perl Archive Network) sites,
+including:
+.IP
+http://search.cpan.org/~pmqs/IO-Compress-Zlib/
+.LP
+A Python interface to
+.IR zlib ,
+written by A.M. Kuchling (amk@magnet.com),
+is available in Python 1.5 and later versions:
+.IP
+http://docs.python.org/library/zlib.html
+.LP
+.I zlib
+is built into
+.IR tcl:
+.IP
+http://wiki.tcl.tk/4610
+.LP
+An experimental package to read and write files in .zip format,
+written on top of
+.I zlib
+by Gilles Vollant (info@winimage.com),
+is available at:
+.IP
+http://www.winimage.com/zLibDll/minizip.html
+and also in the
+.I contrib/minizip
+directory of the main
+.I zlib
+source distribution.
+.SH "SEE ALSO"
+The
+.I zlib
+web site can be found at:
+.IP
+http://zlib.net/
+.LP
+The data format used by the zlib library is described by RFC
+(Request for Comments) 1950 to 1952 in the files:
+.IP
+http://tools.ietf.org/html/rfc1950 (for the zlib header and trailer format)
+.br
+http://tools.ietf.org/html/rfc1951 (for the deflate compressed data format)
+.br
+http://tools.ietf.org/html/rfc1952 (for the gzip header and trailer format)
+.LP
+Mark Nelson wrote an article about
+.I zlib
+for the Jan. 1997 issue of Dr. Dobb's Journal;
+a copy of the article is available at:
+.IP
+http://marknelson.us/1997/01/01/zlib-engine/

+ The 'zlib' compression library provides in-memory compression and
+ decompression functions, including integrity checks of the uncompressed data.
+ This version of the library supports only one compression method (deflation)
+ but other algorithms will be added later and will have the same stream
+ interface.
+
+ Compression can be done in a single step if the buffers are large enough,
+ or can be done by repeated calls of the compression function. In the latter
+ case, the application must provide more input and/or consume the output
+ (providing more output space) before each call.
+
+ The compressed data format used by default by the in-memory functions is
+ the zlib format, which is a zlib wrapper documented in RFC 1950, wrapped
+ around a deflate stream, which is itself documented in RFC 1951.
+
+ The library also supports reading and writing files in gzip (.gz) format
+ with an interface similar to that of stdio using the functions that start
+ with "gz". The gzip format is different from the zlib format. gzip is a
+ gzip wrapper, documented in RFC 1952, wrapped around a deflate stream.
+
+ This library can optionally read and write gzip streams in memory as well.
+
+ The zlib format was designed to be compact and fast for use in memory
+ and on communications channels. The gzip format was designed for single-
+ file compression on file systems, has a larger header than zlib to maintain
+ directory information, and uses a different, slower check method than zlib.
+
+ The library does not install any signal handler. The decoder checks
+ the consistency of the compressed data, so the library should never crash
+ even in case of corrupted input.

+/*
+ deflate compresses as much data as possible, and stops when the input
+ buffer becomes empty or the output buffer becomes full. It may introduce
+ some output latency (reading input without producing any output) except when
+ forced to flush.
+
+ The detailed semantics are as follows. deflate performs one or both of the
+ following actions:
+
+ - Compress more input starting at next_in and update next_in and avail_in
+ accordingly. If not all input can be processed (because there is not
+ enough room in the output buffer), next_in and avail_in are updated and
+ processing will resume at this point for the next call of deflate().
+
+ - Provide more output starting at next_out and update next_out and avail_out
+ accordingly. This action is forced if the parameter flush is non zero.
+ Forcing flush frequently degrades the compression ratio, so this parameter
+ should be set only when necessary (in interactive applications). Some
+ output may be provided even if flush is not set.
+
+ Before the call of deflate(), the application should ensure that at least
+ one of the actions is possible, by providing more input and/or consuming more
+ output, and updating avail_in or avail_out accordingly; avail_out should
+ never be zero before the call. The application can consume the compressed
+ output when it wants, for example when the output buffer is full (avail_out
+ == 0), or after each call of deflate(). If deflate returns Z_OK and with
+ zero avail_out, it must be called again after making room in the output
+ buffer because there might be more output pending.
+
+ Normally the parameter flush is set to Z_NO_FLUSH, which allows deflate to
+ decide how much data to accumulate before producing output, in order to
+ maximize compression.
+
+ If the parameter flush is set to Z_SYNC_FLUSH, all pending output is
+ flushed to the output buffer and the output is aligned on a byte boundary, so
+ that the decompressor can get all input data available so far. (In
+ particular avail_in is zero after the call if enough output space has been
+ provided before the call.) Flushing may degrade compression for some
+ compression algorithms and so it should be used only when necessary. This
+ completes the current deflate block and follows it with an empty stored block
+ that is three bits plus filler bits to the next byte, followed by four bytes
+ (00 00 ff ff).
+
+ If flush is set to Z_PARTIAL_FLUSH, all pending output is flushed to the
+ output buffer, but the output is not aligned to a byte boundary. All of the
+ input data so far will be available to the decompressor, as for Z_SYNC_FLUSH.
+ This completes the current deflate block and follows it with an empty fixed
+ codes block that is 10 bits long. This assures that enough bytes are output
+ in order for the decompressor to finish the block before the empty fixed code
+ block.
+
+ If flush is set to Z_BLOCK, a deflate block is completed and emitted, as
+ for Z_SYNC_FLUSH, but the output is not aligned on a byte boundary, and up to
+ seven bits of the current block are held to be written as the next byte after
+ the next deflate block is completed. In this case, the decompressor may not
+ be provided enough bits at this point in order to complete decompression of
+ the data provided so far to the compressor. It may need to wait for the next
+ block to be emitted. This is for advanced applications that need to control
+ the emission of deflate blocks.
+
+ If flush is set to Z_FULL_FLUSH, all output is flushed as with
+ Z_SYNC_FLUSH, and the compression state is reset so that decompression can
+ restart from this point if previous compressed data has been damaged or if
+ random access is desired. Using Z_FULL_FLUSH too often can seriously degrade
+ compression.
+
+ If deflate returns with avail_out == 0, this function must be called again
+ with the same value of the flush parameter and more output space (updated
+ avail_out), until the flush is complete (deflate returns with non-zero
+ avail_out). In the case of a Z_FULL_FLUSH or Z_SYNC_FLUSH, make sure that
+ avail_out is greater than six to avoid repeated flush markers due to
+ avail_out == 0 on return.
+
+ If the parameter flush is set to Z_FINISH, pending input is processed,
+ pending output is flushed and deflate returns with Z_STREAM_END if there was
+ enough output space; if deflate returns with Z_OK, this function must be
+ called again with Z_FINISH and more output space (updated avail_out) but no
+ more input data, until it returns with Z_STREAM_END or an error. After
+ deflate has returned Z_STREAM_END, the only possible operations on the stream
+ are deflateReset or deflateEnd.
+
+ Z_FINISH can be used immediately after deflateInit if all the compression
+ is to be done in a single step. In this case, avail_out must be at least the
+ value returned by deflateBound (see below). Then deflate is guaranteed to
+ return Z_STREAM_END. If not enough output space is provided, deflate will
+ not return Z_STREAM_END, and it must be called again as described above.
+
+ deflate() sets strm->adler to the adler32 checksum of all input read
+ so far (that is, total_in bytes).
+
+ deflate() may update strm->data_type if it can make a good guess about
+ the input data type (Z_BINARY or Z_TEXT). In doubt, the data is considered
+ binary. This field is only for information purposes and does not affect the
+ compression algorithm in any manner.
+
+ deflate() returns Z_OK if some progress has been made (more input
+ processed or more output produced), Z_STREAM_END if all input has been
+ consumed and all output has been produced (only when flush is set to
+ Z_FINISH), Z_STREAM_ERROR if the stream state was inconsistent (for example
+ if next_in or next_out was Z_NULL), Z_BUF_ERROR if no progress is possible
+ (for example avail_in or avail_out was zero). Note that Z_BUF_ERROR is not

+ inflate decompresses as much data as possible, and stops when the input
+ buffer becomes empty or the output buffer becomes full. It may introduce
+ some output latency (reading input without producing any output) except when
+ forced to flush.
+
+ The detailed semantics are as follows. inflate performs one or both of the
+ following actions:
+
+ - Decompress more input starting at next_in and update next_in and avail_in
+ accordingly. If not all input can be processed (because there is not
+ enough room in the output buffer), next_in is updated and processing will
+ resume at this point for the next call of inflate().
+
+ - Provide more output starting at next_out and update next_out and avail_out
+ accordingly. inflate() provides as much output as possible, until there is
+ no more input data or no more space in the output buffer (see below about
+ the flush parameter).
+
+ Before the call of inflate(), the application should ensure that at least
+ one of the actions is possible, by providing more input and/or consuming more
+ output, and updating the next_* and avail_* values accordingly. The
+ application can consume the uncompressed output when it wants, for example
+ when the output buffer is full (avail_out == 0), or after each call of
+ inflate(). If inflate returns Z_OK and with zero avail_out, it must be
+ called again after making room in the output buffer because there might be
+ more output pending.
+
+ The flush parameter of inflate() can be Z_NO_FLUSH, Z_SYNC_FLUSH, Z_FINISH,
+ Z_BLOCK, or Z_TREES. Z_SYNC_FLUSH requests that inflate() flush as much
+ output as possible to the output buffer. Z_BLOCK requests that inflate()
+ stop if and when it gets to the next deflate block boundary. When decoding
+ the zlib or gzip format, this will cause inflate() to return immediately
+ after the header and before the first block. When doing a raw inflate,
+ inflate() will go ahead and process the first block, and will return when it
+ gets to the end of that block, or when it runs out of data.
+
+ The Z_BLOCK option assists in appending to or combining deflate streams.
+ Also to assist in this, on return inflate() will set strm->data_type to the
+ number of unused bits in the last byte taken from strm->next_in, plus 64 if
+ inflate() is currently decoding the last block in the deflate stream, plus
+ 128 if inflate() returned immediately after decoding an end-of-block code or
+ decoding the complete header up to just before the first byte of the deflate
+ stream. The end-of-block will not be indicated until all of the uncompressed
+ data from that block has been written to strm->next_out. The number of
+ unused bits may in general be greater than seven, except when bit 7 of
+ data_type is set, in which case the number of unused bits will be less than
+ eight. data_type is set as noted here every time inflate() returns for all
+ flush options, and so can be used to determine the amount of currently
+ consumed input in bits.
+
+ The Z_TREES option behaves as Z_BLOCK does, but it also returns when the
+ end of each deflate block header is reached, before any actual data in that
+ block is decoded. This allows the caller to determine the length of the
+ deflate block header for later use in random access within a deflate block.
+ 256 is added to the value of strm->data_type when inflate() returns
+ immediately after reaching the end of the deflate block header.
+
+ inflate() should normally be called until it returns Z_STREAM_END or an
+ error. However if all decompression is to be performed in a single step (a
+ single call of inflate), the parameter flush should be set to Z_FINISH. In
+ this case all pending input is processed and all pending output is flushed;
+ avail_out must be large enough to hold all the uncompressed data. (The size
+ of the uncompressed data may have been saved by the compressor for this
+ purpose.) The next operation on this stream must be inflateEnd to deallocate
+ the decompression state. The use of Z_FINISH is not required to perform an
+ inflation in one step. However it may be used to inform inflate that a
+ faster approach can be used for the single inflate() call. Z_FINISH also
+ informs inflate to not maintain a sliding window if the stream completes,
+ which reduces inflate's memory footprint.
+
+ In this implementation, inflate() always flushes as much output as
+ possible to the output buffer, and always uses the faster approach on the
+ first call. So the effects of the flush parameter in this implementation are
+ on the return value of inflate() as noted below, when inflate() returns early
+ when Z_BLOCK or Z_TREES is used, and when inflate() avoids the allocation of
+ memory for a sliding window when Z_FINISH is used.
+
+ If a preset dictionary is needed after this call (see inflateSetDictionary
+ below), inflate sets strm->adler to the Adler-32 checksum of the dictionary
+ chosen by the compressor and returns Z_NEED_DICT; otherwise it sets
+ strm->adler to the Adler-32 checksum of all output produced so far (that is,
+ total_out bytes) and returns Z_OK, Z_STREAM_END or an error code as described
+ below. At the end of the stream, inflate() checks that its computed adler32
+ checksum is equal to that saved by the compressor and returns Z_STREAM_END
+ only if the checksum is correct.
+
+ inflate() can decompress and check either zlib-wrapped or gzip-wrapped
+ deflate data. The header type is detected automatically, if requested when
+ initializing with inflateInit2(). Any information contained in the gzip
+ header is not retained, so applications that need that information should
+ instead use raw inflate, see inflateInit2() below, or inflateBack() and
+ perform their own processing of the gzip header and trailer. When processing
+ gzip-wrapped deflate data, strm->adler32 is set to the CRC-32 of the output
+ producted so far. The CRC-32 is checked against the gzip trailer.
+
+ inflate() returns Z_OK if some progress has been made (more input processed
+ or more output produced), Z_STREAM_END if the end of the compressed data has
+ been reached and all uncompressed output has been produced, Z_NEED_DICT if a
+ preset dictionary is needed at this point, Z_DATA_ERROR if the input data was
+ corrupted (input stream not conforming to the zlib format or incorrect check
+ value), Z_STREAM_ERROR if the stream structure was inconsistent (for example
+ next_in or next_out was Z_NULL), Z_MEM_ERROR if there was not enough memory,
+ Z_BUF_ERROR if no progress is possible or if there was not enough room in the
+ output buffer when Z_FINISH is used. Note that Z_BUF_ERROR is not fatal, and
+ inflate() can be called again with more input and more output space to
+ continue decompressing. If Z_DATA_ERROR is returned, the application may
+ then call inflateSync() to look for a good compression block if a partial

+ header crc, and the operating system will be set to 255 (unknown). If a
+ gzip stream is being written, strm->adler is a crc32 instead of an adler32.
+
+ The memLevel parameter specifies how much memory should be allocated
+ for the internal compression state. memLevel=1 uses minimum memory but is
+ slow and reduces compression ratio; memLevel=9 uses maximum memory for
+ optimal speed. The default value is 8. See zconf.h for total memory usage
+ as a function of windowBits and memLevel.
+
+ The strategy parameter is used to tune the compression algorithm. Use the
+ value Z_DEFAULT_STRATEGY for normal data, Z_FILTERED for data produced by a
+ filter (or predictor), Z_HUFFMAN_ONLY to force Huffman encoding only (no
+ string match), or Z_RLE to limit match distances to one (run-length
+ encoding). Filtered data consists mostly of small values with a somewhat
+ random distribution. In this case, the compression algorithm is tuned to
+ compress them better. The effect of Z_FILTERED is to force more Huffman
+ coding and less string matching; it is somewhat intermediate between
+ Z_DEFAULT_STRATEGY and Z_HUFFMAN_ONLY. Z_RLE is designed to be almost as
+ fast as Z_HUFFMAN_ONLY, but give better compression for PNG image data. The
+ strategy parameter only affects the compression ratio but not the
+ correctness of the compressed output even if it is not set appropriately.
+ Z_FIXED prevents the use of dynamic Huffman codes, allowing for a simpler
+ decoder for special applications.

+ function trusts the application to not change the output buffer passed by
+ the output function, at least until inflateBack() returns.
+
+ inflateBackInit() must be called first to allocate the internal state
+ and to initialize the state with the user-provided window buffer.
+ inflateBack() may then be used multiple times to inflate a complete, raw
+ deflate stream with each call. inflateBackEnd() is then called to free the
+ allocated state.
+
+ A raw deflate stream is one with no zlib or gzip header or trailer.
+ This routine would normally be used in a utility that reads zip or gzip
+ files and writes out uncompressed files. The utility would decode the
+ header and process the trailer on its own, hence this routine expects only
+ the raw deflate stream to decompress. This is different from the normal
+ behavior of inflate(), which expects either a zlib or gzip header and
+ trailer around the deflate stream.
+
+ inflateBack() uses two subroutines supplied by the caller that are then
+ called by inflateBack() for input and output. inflateBack() calls those
+ routines until it reads a complete deflate stream and writes out all of the
+ uncompressed data, or until it encounters an error. The function's
+ parameters and return types are defined above in the in_func and out_func
+ typedefs. inflateBack() will call in(in_desc, &buf) which should return the
+ number of bytes of provided input, and a pointer to that input in buf. If
+ there is no input available, in() must return zero--buf is ignored in that
+ case--and inflateBack() will return a buffer error. inflateBack() will call
+ out(out_desc, buf, len) to write the uncompressed data buf[0..len-1]. out()
+ should return zero on success, or non-zero on failure. If out() returns
+ non-zero, inflateBack() will return with an error. Neither in() nor out()
+ are permitted to change the contents of the window provided to
+ inflateBackInit(), which is also the buffer that out() uses to write from.
+ The length written by out() will be at most the window size. Any non-zero
+ amount of input may be provided by in().
+
+ For convenience, inflateBack() can be provided input on the first call by
+ setting strm->next_in and strm->avail_in. If that input is exhausted, then
+ in() will be called. Therefore strm->next_in must be initialized before
+ calling inflateBack(). If strm->next_in is Z_NULL, then in() will be called
+ immediately for input. If strm->next_in is not Z_NULL, then strm->avail_in
+ must also be initialized, and then if strm->avail_in is not zero, input will
+ initially be taken from strm->next_in[0 .. strm->avail_in - 1].
+
+ The in_desc and out_desc parameters of inflateBack() is passed as the
+ first parameter of in() and out() respectively when they are called. These
+ descriptors can be optionally used to pass any information that the caller-
+ supplied in() and out() functions need to do their job.
+
+ On return, inflateBack() will set strm->next_in and strm->avail_in to

+ in the deflate stream (in which case strm->msg is set to indicate the nature
+ of the error), or Z_STREAM_ERROR if the stream was not properly initialized.
+ In the case of Z_BUF_ERROR, an input or output error can be distinguished
+ using strm->next_in which will be Z_NULL only if in() returned an error. If
+ strm->next_in is not Z_NULL, then the Z_BUF_ERROR was due to out() returning
