| Implemented by H.J. Lu. |
| |
| * STB_GNU_UNIQUE support added. |
| Implemented by Ulrich Drepper. |
| |
| * Implement second fallback mode for optimized DNS lookup for even more |
| broken environments. If two requests from the same port are not |
| handled correctly close the socket and open a new one before sending |

| can be used to select this mode right away, instead of rediscovering the |
| necessity is every process again. |

| now in POSIX. |
| |
| * New POSIX 2008 interface: psiginfo |
| Implemented by Ulrich Drepper. |

| * New ISO C++1x interfaces: quick_exit, at_quick_exit |
| Implemented by Ulrich Drepper. |
| |
| * Support for selecting between multiple function definitions at runtime |
| using STT_GNU_IFUNC symbols. Implemented by Ulrich Drepper. |
| |
| * The libcrypt library can now use the hash function implementations in |
| NSS. Implemented by Ulrich Drepper. |
| |
| * The malloc implementation can be compiled to be less memory efficient |
| but higher performing in multi-threaded programs. |
| Implemented by Ulrich Drepper. |
| |
| * New locales: nan_TW@latin, ks_IN |
| |
| * Faster strlen, strchr, strchrnul, strrchr, memchr, and rawmemchr for x86-64. |
| Implemented by Ulrich Drepper. |
| |
| * Extended printf hook support. It is possible to use user-defined types |
| and extend existing format specifiers. |
| Implemented by Ulrich Drepper. |
| |
| * Handling for group shadow files has been added. |
| Implemented by Ulrich Drepper. |
| |
| * DNS IPv4-IPv6 parallel lookup now deals better with broken DNS |
| servers (the case, e.g., for some people using the built-in DNS |
| server in ADSL modems/routers). There is a once-per-process timeout |
| in case of a broken server. To avoid it, users can run nscd or put |
| 'options single-request' in /etc/resolv.conf. |
| Implemented by Ulrich Drepper. |

| |
| * Implement "e" option for popen to open file descriptor with the |
| close-on-exec flag set. Implemented by Ulrich Drepper. |
| |
| * Implement "b" mode for fmemopen. In this mode writes writes don't |
| implicitly add a NUL byte and seeks from the end of the buffer really |
| use the buffer end, not the string length as the basis. |
| Implemented by Ulrich Drepper. |
| |
| * Many functions, exported and internal, now atomically set the close-on-exec |
| flag when run on a sufficiently new kernel. Implemented by Ulrich Drepper. |
| |
| * Sorting rules for some Indian languages (Kannada, Gurumukhi, Telugu, |
| Sinhala) |
| Implemented by Pravin Satpute. |

| Implemented by Harsha Jagasia and H.J. Lu. |
| |
| * Faster memcpy on x86. |
| Implemented by Ulrich Drepper. |

| * For Linux, the sorting of addresses returned by getaddrinfo now also |
| handles rules 3, 4, and 7 from RFC 3484. I.e., all rules are handled. |
| Implemented by Ulrich Drepper. |
| |
| * Allow system admin to configure getaddrinfo with the /etc/gai.conf file. |
| Implemented by Ulrich Drepper. |
| |
| * New Linux interfaces: splice, tee, sync_file_range, vmsplice. |
| |
| * New iconv module for MIK. Contributed by Alexander Shopov. |
| |
| * For sites with broken group and/or passwd database, the auto-propagate |
| option of nscd can prevent creating ID lookup entries from the results |
| of a name lookup and vice versa. This usually is no problem but some |
| site might have problems with the default behavior. |
| Implemented by Ulrich Drepper. |
| |
| * Iterating over entire database in NIS can be slow. With the |
| SETENT_BATCH_READ option in /etc/default/nss a system admin can decide |
| to trade time for memory. The entire database will be read at once. |

| * More overflow detection functions. |
| |
| * New iconv converters for IBM1025, IBM1122, IBM1137, IBM1153, |
| IBM1154, IBM1155, IBM1156, IBM1157, and IBM1158 contributed by Jiro Sekiba. |
| |
| More converters for IBM803, IBM901, IBM902, IBM921, IBM1008, IBM1097, |
| IBM1112, IBM1123, IBM1130, IBM1140, IBM1141, IBM1142, IBM1143, IBM1144, |

| IBM16804, IBM1364, IBM1371, IBM1388, IBM1390, and IBM1399 contributed |
| by Masahide Washizawa. |
| |
| * It is now possible to install audit libraries for the dynamic linker using |
| LD_AUDIT. Implemented by Ulrich Drepper. |
| |
| * The LinuxThreads add-on, providing pthreads on Linux 2.4 kernels, is no |
| longer supported. The new NPTL implementation requires Linux 2.6 kernels. |
| For a libc and libpthread that works well on Linux 2.4 kernels, we |
| recommend using the stable 2.3 branch. |
| |
| * The new function open_wmemstream acts like open_memstream, |
| but uses a wchar_t wide character buffer. |
| |
| * The new function ppoll is an improved version of poll, similar to pselect. |
| |
| * New interfaces: fdopendir, openat, fstatat, fchmodat, fchownat, |
| futimesat, faccessat, mkdirat, mkfifoat, mknodat, |
| renameat, unlinkat, linkat, symlinkat, readlinkat. |
| |
| * New Linux kernel system calls: unshare, |
| inotify_init, inotify_add_watch, inotify_rm_watch. |
| |
| * The euidaccess function is now also known by the alias eaccess, |
| for compatibility with some other systems. |
| |
| * Timezone data updated to 2006b version. |
| |
| Version 2.3.6 |
| |
| * The following bugs are resolved with this release: |

| |
| * As of this release, GCC 4 can be used to compile the C Library. |
| |
| * Timezone data updated to 2005m version. |
| |
| Version 2.3.5 |
| |
| * The following bugs are resolved with this release: |
| |
| 284, 592, 602, 626, 633, 640, 650, 661, 671, 681, 693, 700, 710, 719, |

| |
| Version 2.3.4 |
| |
| * Support for RFC 3678. Real implementations exist only for Linux so far. |
| Implemented by Ulrich Drepper. |
| |
| * nscd can now cache entries persistently. Expiring entries are reloaded. |
| For speedups the cache can be shared in memory with client processes. |
| Implemented by Ulrich Drepper. |
| |
| * nscd can now perform SELinux checks. |
| Implemented by Matthew Rickard <mjricka@epoch.ncsc.mil>. |
| |
| * getaddrinfo queries are now cached. Canonical name lookup is performed |
| efficiently. |
| Implemented by Ulrich Drepper. |
| |
| * The nothrow function attribute is used when headers are used by gcc when |
| compiling C code. This can avoid significant amounts of exception |
| handling data. |
| |
| * The malloc functions perform more error checking and are stricter when |
| it comes to reacting on errors. The default action is to terminate |
| the process after showing an error message. Implemented by Ulrich Drepper. |
| |
| * Reverse lookups of IPv6 addresses does not use bit string or .ip6.int |
| lookups anymore unless explicitly requested. Implemented by Ulrich Drepper. |
| |
| * Namespaces in ld.so are implemented. DSOs can be loaded in separate |
| namespaces using the new function dlmopen(). This feature is of course, |
| like most other dynamic loading functionality, not available in statically |
| linked applications. Implemented by Ulrich Drepper. |
| |
| * Low-overhead boundary checking variants of string and some stdio functions |
| were added. These are to be used in conjunction with a gcc patch by |
| Jakub Jelinek which adds calls to these functions if possible. |
| Implemented by Jakub Jelinek and Ulrich Drepper. |
| |
| * Old code for several operating systems and machine architectures that |
| have not been in working condition in a long time have been removed from |
| the main source tree maintained by the GNU C Library's maintainers. |
| These files are now reside in the separate `ports' source module |
| that is usable as an add-on when building the library. |
| |
| Version 2.3.3 |
| |
| * New functions `dladdr1' and `dlinfo' in <dlfcn.h> provide more ways to |
| interrogate the dynamic linker, compatible with the Solaris interface. |
| |
| * ELF thread-local storage support (TLS) now works on PowerPC and PowerPC64; |
| implemented by Paul Mackerras, Steven Munroe, and Roland McGrath. |
| |
| * getifaddrs now uses the netlink interface on Linux to get its information. |
| Implemented by Thorsten Kukuk. |
| |
| * getaddrinfo now implements AI_V4MAPPED, AI_ALL, and AI_ADDRCONF. |
| Implemented by Ulrich Drepper. |
| |
| * support for non-executable stacks on x86 has been added. Changes mostly |
| by Roland McGrath. |
| |
| * regex is now much faster for multibyte locales. Changes by Jakub Jelinek |
| and Ulrich Drepper. |
| |
| * getaddrinfo now performs destination address selection according to |
| RFC 3484. |
| |
| Version 2.3.2 |
| |
| * Thread-safe interfaces for many functions that access locale data |
| were added in version 2.3, but these features were omitted from NEWS. |
| Many functions have variants with an `_l' suffix that take a `locale_t' |
| object as a parameter rather than consulting the current locale. |
| The new functions `newlocale', `duplocale', and `freelocale' in <locale.h> |
| create and maintain `locale_t' objects. Additionally, the new function |
| `uselocale' sets "the current locale" (as used by functions not so |
| parameterized) set for an individual thread. These features were added |
| in version 2.3, implemented by Ulrich Drepper and Roland McGrath. |
| |
| * The functions getresuid, getresgid, setresuid, and setresgid, which |
| have long been available on Linux, are now declared in <unistd.h> |
| and are now also available on the Hurd. |
| |
| * ELF thread-local storage support (TLS) now works on x86-64. |
| |
| * The new dynamic string token $LIB is expanded in shared library names. |
| This normally expands to lib, but on some 64-bit platforms to lib64 instead. |
| |
| * Aldy Hernandez contributed complete software floating point support for |
| PowerPC machines with no FPU. |
| |
| * fexecve is implemented on Linux. |
| |
| * The `btowc' function should work at least twice as fast due to |
| specialized callbacks in the iconv modules. Implemented by Bruno Haible. |
| |
| * With approriate thread add-ons cancelable functions are now implemented |
| in libc.so as well. No need to call the function in libpthread. This |
| change allowed to finally disable the incorrect and expensive handling |
| of weak definition in ld.so. |
| |
| * Yet more PLT entries in libc.so have been removed. We finally arrived |
| at the bare minimum. Startup times improved appropriately. |
| |
| * Support for the new Linux/x86 system call interface was added. The |
| AT_SYSINFO auxiliary vector entry is recognized and handled. |
| |
| Version 2.3 |
| |
| * Masahide Washizawa contributed iconv modules for IBM1163 and IBM1164 |
| charsets. |
| |
| * iconv (the program and the interface) now accepts empty names (excluding |
| options like //TRANSLIT) to mean "use charset of current locale". |
| |
| * localedef can now transliterate characters in strings which are not in |
| the provided charmap. The information from the input locale is used. |
| |
| * Prelinking support was added for ELF targets. This requires additional |
| tools and recent versions of the GNU binutils. Contributed by Jakub Jelinek. |
| |
| * Read-only stdio streams now use mmap to speed up operation by eliminating |
| copying and buffer underflows. To use add 'm' to the mode string of |
| the fopen/fdopen/freopen call. Implemented by Ulrich Drepper. |
| |
| * The malloc functions were completely rewritten by Wolfram Gloger based |
| on Doug Lea's malloc-2.7.0.c. |
| |
| * Isamu Hasegawa contributed a completely new and POSIX-conformant |
| implementation of regex. |
| |
| * Bruno Haible upgraded the iconv and locale implementation to support |
| Unicode 3.2. |
| |
| * Contents of the LC_* and LANG environment variables in the CEN style are |
| not recognized anymore. It never was used. Change by Ulrich Drepper. |
| |
| * The runtime (ld.so, libc, libpthread for Linux) now can handle the ELF |
| thread-local storage (TLS) ABI on some platforms. |
| Changes by Ulrich Drepper. SH support by Kaz Kojima. |
| |
| * Bruno Haible contributed iconv converters for ISO-2022-JP-3, SHIFT JIS-X0213, |
| EUC-JISX0213, and TSCII. |
| |
| * New header <ifaddrs.h> with functions `getifaddrs' and `freeifaddrs': |
| BSD-compatible interface for getting all network interface addresses. |
| Implementation for IPv4 by Roland McGrath. |
| |
| * Loading of locale data is faster due to the introduction of a locale |
| archive. Implemented by Roland McGrath and Ulrich Drepper. |
| |
| * Startup times are significantly reduced by not using exported functions |
| inside the library itself. Changes by Jakub Jelinek, Roland McGrath, |
| and Ulrich Drepper. |
| |
| * Steven Munroe contributed a port to PowerPC64/Linux. |
| |
| Version 2.2.6 |
| |
| * The Hurd now uses the GNU libio implementation of stdio rather than the |
| old GNU stdio implementation, and uses a new ABI (libc.so.0.3). |
| |
| * The Hurd on x86 now has the `ioperm' function and <sys/io.h> header file |
| with the same behavior as the Linux system call of the same name. |
| |
| Version 2.2.5 |
| |
| * Stephen Moshier implemented log2, log10, powl and cbrtl for the |
| 128-bit long double format. |
| |
| * Masahide Washizawa contributed iconv modules for IBM1132, IBM1133, IBM1160, |
| IBM1161, and IBM1162 charsets. |
| |
| * Andreas Jaeger contributed a port to x86-64/Linux. |
| |
| * Peter Bruin contributed a port to PowerPC/Hurd. |
| |
| * libc functions using I/O streams now can handle wide-oriented streams |
| as well. |
| |
| * optimizations in the dynamic linker. Binaries created by recent binutils |
| versions start up quicker due to reduced time spent on relocations. |
| |
| * Support for use of gcc3 added by Jakub Jelinek and HJ Lu. |
| |
| Version 2.2.4 |
| |
| * Stephen Moshier implemented cosh, expm1, log1p, acos, sinh, tanh, |
| asinh, atanh, j0 for the 128-bit long double format. |
| |
| * Bruno Haible updated all the code handling Unicode in some form to |
| support Unicode 3.1. |
| |
| * Speed of regex for single-byte locales is back to previous levels. |
| Patch by Isamu Hasegawa. |
| |
| * Alpha, SPARC, and IA-64 now also using floating stacks. |
| |
| * Startup time of internationalized applications greatly improved through |
| iconv cache. Use iconvconfig to generate the cache file. |
| Contributed by Ulrich Drepper. |
| |
| * The IA-64 specific part of ld.so was rewritten to eliminate some pretty |
| severe performance problems. Patch by David Mosberger. |
| |
| * The Hurd port got a lot more functionality like AIO, various stdio |
| extensions, etc. Mainly done by Roland McGrath. |
| |
| * mtrace can now lookup symbols in shared libraries. |
| |
| Version 2.2.3 |
| |
| * Intel's IA-64 math library is largely integrated. It provides fast and |
| accurate implementatations for most basic and standard math functions |
| in float, double, and long double format. |
| |
| * Stephen Moshier implemented j0, j1, jn, y0, y1, yn, lgamma, erf, erfc, |
| and asin for the 96-bit long double format and asin, log, tan for the |
| 128-bit long double format. |
| |
| * The beginning of a last-bit accurate math library by IBM Haifa were added. |
| The basic double functions exist today. Contributed by Abraham Ziv |
| <ziv@il.ibm.com>, Moshe Olshansky <olshansk@il.ibm.com>, Ealan Henis |
| <ealan@il.ibm.com>, and Anna Reitman <reitman@il.ibm.com>. |
| |
| * An asynchronous name lookup library was added. The interface is designed |
| after POSIX AIO. The proposal was circulated beforehand to get comments. |
| No negative ones came in. Implemented by Ulrich Drepper. |
| |
| * Port to S390/64bit contributed by Martin Schwidefsky |
| <schwidefsky@de.ibm.com>. |
| |
| * David Mosberger <davidm@hpl.hp.com> implemented the setcontext family |
| of functions for Linux/IA-64. |
| |
| * The RPC code is now thread safe. Threads can now use the same service |
| of different services at the same time. Patch by Eric Norum |
| <eric.norum@usask.ca> with some help by Ulrich Drepper. |
| |
| * Martin Schwidefsky <schwidefsky@de.ibm.com> implemented the setcontext |
| family of functions for Linux/S390. |
| |
| * Ulrich Drepper <drepper@redhat.com> implemented the setcontext family |
| of functions for Linux/x86. |
| |
| * Port to Linux/CRIS contributed by Axis Communications. |
| |
| Version 2.2.2 |
| |
| * Lots of headers were cleaned up. Using the tool in the conform/ subdir |
| we can now check for namespace violations and missing declarations. The |
| result is that almost all headers are now Unix-compliant (as defined in |
| the upcoming XPG6). The negative side is that some programs might need |
| corrections, too, if they depend on the incorrect form of the headers in |
| previous versions which defined too many symbols and included too many |
| other headers. |
| |
| * regex now handles multibyte character sets correctly. |
| Contributed by Isamu Hasegawa <isamu@yamato.ibm.com>. |
| |
| * iconv (the program) does now conform to the upcoming XPG6 and handles |
| charmaps. Instead of the charset names the path of charmaps can be |
| provided and the conversion happens based on this data. |
| Contributed by Ulrich Drepper. |
| |
| * The locale program now provides detailed information about the installed |
| locales. While |
| |
| locale -a |
| |
| only lists the names of the supported locales |
| |
| locale -a --verbose |
| |
| provides details such as country, language, and codeset name. |
| Contributed by Ulrich Drepper. |
| |
| Version 2.2.1 |
| |
| * The gencat program now parses the input file according to the charset |
| selected by the LC_CTYPE category. This is important for stateful |
| character sets. To make generating catalogs easier there is a way |
| to overwrite the charset selected by the locale: before the first |
| message or $ quote line the catalog can contain a line like |
| |
| $ codeset=ISO-8859-2 |
| |
| to select the charset (ISO-8859-2 in this case). |
| |
| Implemented by Shinya Hanataka and Ulrich Drepper. |
| |
| * New codeset conversion modules: IBM-922 (Estonia PC codeset), |
| IBM-1124 (Ukraine PC codeset), IBM-1129 (Vietnamese PC codeset). |
| Contributed by Masahide Washizawa <washi@jp.ibm.com>. |
| |
| * Optimized string functions for Alpha ev6 and ev67 by Richard Henderson |
| <rth@redhat.com> and Rick Gorton <rick.gorton@alpha-processor.com>. |
| |
| * The LANGUAGE environment variable is now ignored unless the locale is |
| changed from the default "C" locale. |
| |
| * The usual bug fixes. |
| |
| Version 2.2 |
| |
| * Greg McGary added runtime support for bounds checking using gcc's |
| new -fbounded-pointers option. ix86 target is complete. PowerPC |
| is in progress. |
| |
| * Thorsten Kukuk added secure mode support to nscd. |
| |
| * The Berkeley db libraries have been removed. |
| |
| Related, the nss_db module is now in a separate package since it |
| obviously requires a database library being available. |
| |
| * Wide character I/O streams implemented by Ulrich Drepper. |
| |
| * Functions from the extended socket API added by Ulrich Drepper. |
| |
| * Functions feenableexcept and fedisableexcept to control the |
| behaviour of individual exceptions have been added by Andreas Jaeger. |
| |
| * ldconfig program added by Andreas Jaeger and Jakub Jelinek. |
| |
| * The resolver code has been updated from bind 8.2.3-T5B which supports |
| threads. The integration was done by Andreas Jaeger, Adam D. Bradley, |
| and Mark Kettenis. |
| |
| This change could in some situations effect backward compatibility. Since |
| now `_res' is a thread-local instead of a global variable, modifying it |
| in one thread does not have any effect in other threads. |
| |
| The resolver library was also extended to allow IPv6 as the transport |
| protocol for the requests. This work was done by Stig Venaas. |
| |
| * Compatibility code for K&R C compilers has been removed from the |
| header files. A ISO C compiler is needed to use the library |
| (conforming to either C89 or C99 standard). |
| |
| * Complete rewrite of the localedef program to support multibyte character |
| sets. Implement handling of ISO 14651 and ISO 14652. Rewrite strcoll, |
| strxfrm, wcscoll, and wcsxfrm functions. Make isw*() functions work. |
| Implemented by Ulrich Drepper. |
| |
| Bruno Haible significantly improved the generation and use of the data |
| structures for the wide character tables. |
| |
| * Plural handling in gettext implemented by Ulrich Drepper. |
| |
| * The utmp daemon has been removed. |
| |
| * The port to MIPS-Linux has been finished by Andreas Jaeger. |
| |
| * A port to Hitachi SH3 and SH4 has been contributed by Kazumoto Kojima |
| and Yutaka Niibe. |
| |
| * POSIX clocks and timers implemented by Kaz Kylheku and Ulrich Drepper. |
| |
| * POSIX barriers implemented by Kaz Kylheku. |
| |
| * POSIX spawn function family implemented by Ulrich Drepper. |
| |
| * POSIX spinlocks are now available. |
| |
| * Timed wait functions for mutex, rwlock, and semaphores are implemented. |
| |
| * the configure option --enable-kernel=X.Y.Z allows to strip out |
| compatibility for kernel versions before X.Y.Z. This is currently only |
| implemented for Linux. |
| |
| * the sockaddr_in6 structure changed. The IPv6 working group added a new |
| field sin6_scope_id. This means that all programs using IPv6 should be |
| recompiled. Don't expect binary compatibility with previous glibc |
| versions. |
| |
| * various conversion modules for IBM character sets contributed by |
| Masahide Washizawa. |
| |
| * IA-64 port by Jes Sorensen and HJ Lu. |

| Compiling the GNU C Library for Linux/ia64 |
| ****************************************** |
| |
| Please refer to the file INSTALL in the same directory as you found |
| this file for general information about configuring and compiling |
| glibc. |
| |
| For general inquiries about glibc under Linux/ia64 please use the |
| following mailing list linux-ia64@linuxia64.org or one of the relevant |
| glibc mailing lists. |
| |
| Recommended Tools for Compilation |
| ================================= |
| |
| In order for glibc-2.2 to build correctly on the ia64 you need at |
| least the following versions of the GNU tools (the : |
| |
| * The Cygnus toolchain snapshot for the ia64 as of August 4 |
| including the provided set of patches. It is however recommend |
| you use the October 24 toolchain snapshot or a more recent version. |
| |
| OR alternatively you can try the following (the Cygnus toolchain is |
| the recommended solution): |
| |
| * GCC and binutils, GAS and GNU LD out of CVS from |
| sources.redhat.com as of August 28, 2000 or later. The CVS tree |
| may require special patches to work properly on the ia64. |
| |
| Configuring and compiling GNU Libc for Linux/ia64 |
| ================================================= |
| |
| The library requires Linux kernel version 2.4.0-test4-000728 or |
| later to funtion properly. Besides that it support for debug libraries |
| is currently untested. Hence the following options |
| are required for configuring the library: |
| |
| --disable-debug --enable-kernel=2.4.0 |
| |
| It is also important that you make sure the library picks up the |
| appropriate kernel header files, if you do not have recent enough |
| kernel headers in /usr/src/linux/include, you should use the |
| --with-headers=<path> option to specify the location. |
| |
| As an example I personally use the following options to configure |
| the library: |
| |
| --disable-debug |
| --disable-cvs |
| --enable-kernel=2.4.0 |
| --host=ia64-linux |
| --enable-add-ons=yes |
| --prefix=/usr |
| --with-headers=/home/jes/linux/include |
| |
| |
| Good luck |

| |
| Version 2.1.3 |
| |
| * bug fixes |
| |
| |
| Version 2.1.2 |
| |
| * bug fixes |
| |
| |
| Version 2.1.1 |
| |
| * New ISO C 9x function _Exit, imaxabs, and imaxdiv are added. |
| |
| * New xdr functions are added; some rpc functions are now 64bit clean. |
| |
| * Fixed a number of bugs and memory leaks (especially in NIS+ code). |
| |
| * Fixed known incompatibilities with glibc 2.0. |
| |
| * New functions lock64, strchrnul, rawmemchr, getutmp and getutmpx. |
| |
| * Optimized a number of functions (especially the ELF dynamic loader). |
| |
| * Update timezone data files. |
| |
| * lots of charmaps corrections |
| |
| * some new locale definitions and charmaps |
| |
| |
| Version 2.1 |
| |
| * Richard Henderson corrected size of struct timeval on Linux/Alpha to |
| conform to POSIX member type requirements. Symbol versions have been |
| adjusted as needed within the library, and for direct use by applications, |
| but there is potential for problems if third-party libraries use |
| struct timeval as part of their interface. This does not present |
| a problem for X and other "essential" system libraries. |
| |
| * An additional locale model to support C++ Standard Library locale |
| model and probably more was implemented by Ulrich Drepper. |
| |
| * Eric Youngdale and Ulrich Drepper implemented versioning of objects on |
| symbol level. |
| |
| * Miles Bader provided the `argp' function family to support hierachical |
| command line argument parsing, layered on top of getopt. |
| |
| * strtod accepts new hexadecimal floating-point format from ISO C 9X. |
| |
| * printf has two new specifiers %a and %A to print hexadecimal flaoting-point |
| numbers. |
| |
| * scanf recognizes the %a and %A format for scanning floating point numbers. |
| |
| * the new headers <stdint.h> and <inttypes.h> from ISO C 9X provides |
| information and interfaces for the available integer types. |
| |
| * about 130 new math functions were added to implement the ISO C9x math |
| library. |
| |
| * the new header <complex.h> contains definitions of the complex math |
| functions from ISO C 9X. |
| |
| * the new header <tgmath.h> defines generic macros to use complex or |
| real valued functions. |
| |
| * Thorsten Kukuk provided an implementation for NIS+, securelevel 0, 1 and 2. |
| |
| * Andreas Jaeger provided a test suite for the math library. |
| |
| * Mark Kettenis implemented the utmpx interface and an utmp daemon. |
| |
| * Ulrich Drepper added character set conversion functions (iconv). |
| |
| * Optimized string functions have been added. |
| |
| * The localedata addon is now part of glibc. |
| |
| * An implementation of profiling shared libraries was added by Ulrich Drepper. |
| |
| * Thorsten Kukuk and Ulrich Drepper provided an implementation for a caching |
| daemon for NSS (nscd). |
| |
| Missing a better place here are some numbers on improvements. Under |
| Linux 2.1.125 un-tar-ing the kernel sources takes |
| |

| |
| * fix math functions |
| |
| Version 2.0.1 |
| |
| * fixed lots of header problems (especially Linux/GNU specific) |
| |
| * dynamic loader preserves all registers |
| |
| * Roland McGrath provided support for handling of auxiliary objects in |
| the ELF dynamic loader. |
| |
| * support for parallel builds is improved |
| |
| Version 2.0 |
| |
| * GNU extensions are no longer declared by default. To enable them you |
| must define the macro `_GNU_SOURCE' in your program or compile with |
| `-D_GNU_SOURCE'. |
| |
| * The library has changed from using GNU ld symbol aliases to using weak |
| symbols where available. The ELF object file format supports weak |
| symbols; GNU ld also supports weak symbols in the a.out format. (There |
| is also now support for other GNU ld extensions in ELF. Use the |
| `--with-elf' option to configure to indicate you have ELF, and |
| `--with-gnu-ld' if using GNU ld.) This change resulted in the deletion |
| of many files which contained only symbol aliases, reducing the size of |
| the source and the compiled library; many other files were renamed to |
| less cryptic names previously occupied by the symbol alias files. |
| There is a new header file <elf.h> for programs which operate on |
| files in the ELF format. |
| |
| * Converted to Autoconf version 2, so `configure' has more options. |
| Run `configure --help' to see the details. |
| |
| * The library can now be configured to build profiling, highly-optimized |
| (but undebuggable), and/or shared libraries (ELF with GNU ld only). The |
| `--enable-profile', `--enable-omitfp', and `--enable-shared' options to |
| `configure' enable building these extra libraries. The shared library is |
| built by default when using both ELF and GNU ld. When shared libraries |
| are enabled, the new library `-ldl' is available for arbitrary run-time |
| loading of shared objects; its interface is defined in <dlfcn.h>. The |
| new header file <link.h> gives access to the internals of the run-time |
| dynamic linker, `ld.so'. The shell script `ldd' is similar to the |
| application of same name on other systems and it provides information |
| about dynamically linked binaries. |
| |
| * The C library now provides the run-time support code for profiling |
| executables compiled with `-pg'. Programs can control the profiling code |
| through the interface in <sys/gmon.h>. The `gmon.out' files written by |
| the GNU C library can be read only by GNU `gprof' (from GNU binutils); |
| the support for this file format was contributed by David Mosberger-Tang. |
| |
| * The math code has been replaced with a math library based on fdlibm from |
| Sun, and modified by JT Conklin and Ulrich Drepper with i387 support, by |
| Ian Taylor with `float' functions and by Ulrich Drepper with `long double' |
| functions. The math functions now reside in a separate library, so |
| programs using them will need to use `-lm' their linking commands. |
| |
| * John C. Bowman contributed optimized ix87 assembler inline functions. |
| |
| * Ulrich Drepper has contributed support for an `/etc/nsswitch.conf' |
| mechanism similar to that found in Solaris 2. This is now used for the |
| group, passwd, hosts, networks, services, protocols, rpc, ethers, |
| shadow, netgroup, publickey, and alias databases. The `nsswitch.conf' |
| file controls what services are used for each individual database. This |
| works by loading shared libraries with names specified in `nsswitch.conf', |
| so service modules can be changed or added at any time without even |
| relinking any program. Currently there are the file, db, and NIS based |
| NSS services available. |
| |
| * The new functions `strtoq' and `strtouq' parse integer values from |
| strings, like `strtol' and `strtoul', but they return `long long int' and |
| `unsigned long long int' values, respectively (64-bit quantities). |
| |
| * The new functions `strtof' and `strtold' parse floating-point values from |
| strings, like `strtod', but they return `float' and `long double' values, |
| respectively (on some machines `double' and `long double' are the same). |
| |
| * Ulrich Drepper has contributed new implementations of the floating-point |
| printing and reading code used in the `printf' family of functions and |
| `strtod', `strtof', and `strtold'. These new functions are perfectly |
| accurate, and much faster than the old ones. |
| |
| * The implementation of the POSIX locale model was completely rewritten by |
| Ulrich Drepper. This includes the new programs `localedef' and `locale' |
| to compile the POSIX locale definition. |
| |
| * The former dummy implementations of the strcoll and strxfrm function are |
| now replaced by fully functional code contributed by Ulrich Drepper. The |
| collation information comes from the POSIX locale definitions. |
| |
| * The new header <langinfo.h> defines an interface for accessing |
| various locale-dependent data (using the locale chosen with `setlocale'). |
| |
| * Ulrich Drepper has contributed a new suite of functions for operation on |
| wide-character and multibyte-character strings, in <wchar.h>; |
| and classification and case conversion of wide characters, in <wctype.h>. |
| These new functions are conforming to the ISO C, Amendement 1 specification. |
| |
| * There is now a second implementation of the standard I/O library available. |
| It comes from GNU libg++ as was written by Per Bothner, heavily modified |
| by Hongjiu Lu and made thread safe by Ulrich Drepper. |
| |
| * You can now use positional parameter specifications in format strings |
| for the `printf' and `scanf' families of functions. For example, |
| `printf ("Number %2$d, Mr %1$s\n", "Jones", 6);'' prints |
| ``Number 6, Mr Jones''. This is mainly useful when providing different |
| format strings for different languages, whose grammars may dictate |
| different orderings of the values being printed. To support this |
| feature, the interface for `register_printf_handler' has changed; see |
| the header file <printf.h> for details. |
| |
| * The `printf' and `scanf' families of functions now understand a new |
| formatting flag for numeric conversions: the ' flag (e.g. %'d or %'f) says |
| to group numbers as indicated by the locale; for `scanf' and friends, this |
| says to accept as valid only a number with all the proper grouping |
| separators in the right places. In the default "C" locale, numbers are |
| not grouped; but locales for specific countries will define the usual |
| conventions (i.e. separate thousands with `,' in the US locale). |
| |
| * The pgrp functions have been regularized, slightly incompatibly but much |
| less confusingly. The core functions are now `getpgid' and `setpgid', |
| which take arguments for the PID to operate on; the POSIX.1 `getpgrp' (no |
| argument) and BSD `setpgrp' (identical to `setpgid') functions are |
| provided for compatibility. There is no longer an incompatible `getpgrp' |
| with an argument declared under _BSD_SOURCE; no BSD code uses it. |
| |
| * The new header file <fts.h> and suite of functions simplify programs that |
| operate on directory trees. This code comes from 4.4 BSD. |
| |
| * The resolver code has been updated from the BIND 4.9.5-P1 release. |
| Parts of the code were heavily modified by Ulrich Drepper to fit in the |
| NSS scheme used in glibc. |
| |
| * There is a new malloc debugging hook `__memalign_hook'. |
| |
| * There are new typedefs `ushort' for `unsigned short int' and `uint' for |
| `unsigned int' in <sys/types.h>. These are for compatibility only and |
| their use is discouraged. |
| |
| * The `-lmcheck' library to enable standard malloc debugging hooks is now |
| done differently, so that it works even without GNU ld. |
| |
| * New function `euidaccess' checks allowed access to a file like `access', |
| but using the effective IDs instead of the real IDs. |
| |
| * The time zone data files have been updated for the latest and greatest |
| local time conventions of the countries of the world. |
| |
| * The new function `dirfd' extracts the file descriptor used by a DIR stream; |
| see <dirent.h>. |
| |
| * The new functions `ecvt', `fcvt', and `gcvt' provide an obsolete interface |
| for formatting floating-point numbers. They are provided only for |
| compatibility; new programs should use `sprintf' instead. There are |
| also equivalent function for the `long double' floating-point type and |
| all functions also exist in a reentrant form. |
| |
| * The new auxiliary library `-lutil' from 4.4 BSD contains various |
| functions for maintaining the login-record files (primarily of use to |
| system programs such as `login'), and convenient functions for |
| allocating and initializing a pseudo-terminal (pty) device. |
| |
| * Ulrich Drepper has contributed new support for System V style |
| shared memory and IPC on systems that support it. |
| |
| * Ulrich Drepper has contributed several miscellaneous new functions found |
| in System V: The `hsearch' family of functions provide an effective |
| implementation of hash tables; `a64l' and `l64a' provide a very simple |
| binary to ASCII mapping; `drand48' and friends provide a 48-bit random |
| number generator. |
| |
| * Ulrich Drepper has contributed new reentrant counterparts for the |
| `random' and `hsearch' families of functions; `random_r', `hsearch_r', etc. |
| |
| * Ulrich Drepper has contributed new, highly-optimized versions of several |
| string functions for the i486/Pentium family of processors. |
| |
| * Ulrich Drepper has updated the Linux-specific code, based largely |
| on work done in Hongjiu Lu's version of GNU libc for Linux. |
| The GNU library now supports Linux versions 2.0.10 and later, |
| using the ELF object file format (i[3456]86-*-linux). |
| |
| * Andreas Schwab has ported the C library to Linux/m68k (m68k-*-linux). |
| |
| * David Mosberger-Tang and Richard Henderson have ported the C library |
| to Linux/Alpha (alpha-*-linux). Richard Henderson contributed the |
| dynamic linking support for ELF/Alpha. |
| |
| * Richard Henderson contributed several Alpha optimized assembler function |
| for arithmetic and string handling. |
| |
| * Ulrich Drepper has contributed a new set of message catalog functions to |
| support multiple languages using the <libintl.h> interface, for use with |
| his new package GNU gettext. Translation volunteers have contributed |
| catalogs of the library's messages in Spanish, German, and Korean. |
| |
| * For compatibility with XPG4, Ulrich Drepper has contributed the `gencat' |
| program and the `catgets' function for reading the catalog files it |
| creates. (The <libintl.h> interface is preferred; we include the |
| <nl_types.h> interface using `catgets' only for source compatibility with |
| programs already written to use it.) |
| |
| * New header file <values.h> gives SVID-compatible names for <limits.h> |
| constants. |
| |
| * Various new macros, declarations, and small header files for compatibility |
| with 4.4 BSD. |
| |
| * New function `group_member' is a convenient way to check if a process has |
| a given effective group ID. |
| |
| * When using GCC 2.7 and later, the socket functions are now declared in a |
| special way so that passing an argument of type `struct sockaddr_in *', |
| `struct sockaddr_ns *', or `struct sockaddr_un *' instead of the generic |
| `struct sockaddr *' type, does not generate a type-clash warning. |
| |
| * New function `error' declared in header file <error.h> is a convenient |
| function for printing error messages and optionally exiting; this is the |
| canonical function used in GNU programs. The new functions `err', `warn', |
| and friends in header file <err.h> are the canonical 4.4 BSD interface for |
| doing the same thing. |
| |
| * The <glob.h> interface has several new flags from 4.4 BSD that extend the |
| POSIX.2 `glob' function to do ~ and {...} expansion. |
| |
| * New function `unsetenv' complements `setenv' for compatibility with 4.4 BSD. |
| `clearenv' which is used in POSIX.9 is also available. |
| |
| * New function `getsid' returns session ID number on systems that support it. |
| |
| * We have incorporated the 4.4 BSD `db' library (version 1.85). New header |
| files <db.h> and <mpool.h> provide a rich set of functions for several |
| types of simple databases stored in memory and in files, and <ndbm.h> is |
| an old `ndbm'-compatible interface using the `db' functions. Link with |
| `-ldb' to get these functions. |
| |
| * New macro `strdupa' copies a string like `strdup', but uses local stack |
| space from `alloca' instead of dynamic heap space from `malloc'. |
| |
| * New function `strnlen' is like `strlen' but searches only a given maximum |
| number of characters for the null terminator. `stpncpy', `strndup' and |
| `strndupa' are similar variants for the `stpcpy', `strdup' and `strdupa' |
| function. |
| |
| * New function `statfs' in header <sys/statfs.h>. |
| |
| * The new <argz.h> and <envz.h> interfaces contributed by Miles Bader |
| provide convenient functions for operating on blocks of null-terminated |
| strings. |
| |
| * A new suite of functions in <utmp.h> handle all the details of reading |
| and writing the utmp file. |
| |
| * An implementation of the NIS/YP(tm) based NSS service was contributed by |
| Thorsten Kukuk. |
| |
| * Paul Eggert and Ulrich Drepper modified the `strftime' function to be |
| completely POSIX compliant and also implemented the extended functionality |
| to handle alternate digit representation and alternate era date formats. |
| |
| * Ulrich Drepper provided an implementation of the `strptime' function |
| defined in XPG4.2 which transforms a string into a `struct tm' value. |
| |
| * Paul Eggert provided the tzselect shell script as part of the timezone |
| code. The shell script makes it easy to select the correct timezone |
| specification. |
| |
| * The implementation of the malloc family of functions is completely replaced |
| by a new implementation by Doug Lea with many improvements by Wolfram Gloger. |
| The implementation uses the mmap function (if available) and it is |
| optimized for the use in multi threaded programs. |
| |
| * Ulrich Drepper contributed a MD5 "encryption" for the crypt family of |
| functions. This new functionality is usable by specifying a special |
| salt string and it is compatible with implementation on *BSD systems. |
| |
| * Lots of functions from the XPG4.2 standard were added by Ulrich Drepper: |
| `getsubopt' to handle second level command line options, `bsd_signal' |
| to access BSD style `signal' functionality, the obsolete `regexp' style |
| expression matcher. |
| |
| * the `lchown' function is available on system which support this |
| functionality. |
| |
| * The implementation of the shadow password handling function was contributed |
| by Ulrich Drepper. |
| |
| * David Mosberger-Tang changed the SunRPC implementation to be 64bit safe. |
| |
| * POSIX.1g support was added. The <sys/select.h> header is available, |
| `isfdtype' and `pselect' are implemented. Craig Metz contributed an |
| implementation of `getaddrinfo'. |
| |
| Version 1.09 |
| |
| * For cross-compilation you should now set `BUILD_CC' instead of `HOST_CC'. |
| |
| * New header file <fstab.h> and new functions `getfsspec', `getfsent' and |
| friends, for parsing /etc/fstab. This code comes from 4.4 BSD. |
| |
| * The new function `daemon' from 4.4 BSD is useful for server programs that |
| want to put themselves in the background. |
| |
| * Joel Sherrill has contributed support for several standalone boards that |
| run without an operating system. |
| |
| * `printf', `scanf' and friends now accept a `q' type modifier for long |
| long int as well as `ll'. Formats using these might be `%qu' or `%lld'. |
| |
| * All of the code taken from BSD (notably most of the math and networking |
| routines) has been updated from the BSD 4.4-Lite release. |
| |
| * The resolver code has been updated from the BIND-4.9.3-BETA9 release. |
| |
| * The new functions `getdomainname' and `setdomainname' fetch or change the |
| YP/NIS domain name. These are system calls which exist on systems which |
| have YP (aka NIS). |
| |
| * The time zone data files have been updated for the latest international |
| conventions. |
| |
| * The SunRPC programs `portmap' and `rpcinfo' are now installed in |
| $(sbindir) (usually /usr/local/sbin) instead of $(bindir). |
| |
| Version 1.08 |
| |
| * The C library now includes support for Sun RPC, from Sun's free |
| RPCSRC-4.0 distribution. The `portmap', `rpcinfo', and `rpcgen' programs |
| are included. (There is still no support for YP.) |
| |
| * Tom Quinn has contributed a port of the C library to SGI machines running |
| Irix 4 (mips-sgi-irix4). |
| |
| * The new `lockf' function is a simplified interface to the locking |
| facilities of `fcntl', included for compatibility. |
| |
| * New time functions `timegm', `timelocal', and `dysize' for compatibility. |
| |
| * New header file <sys/timeb.h> and new function `ftime' for compatibility. |
| |
| * New header files <poll.h> and <sys/poll.h> and new function `poll' for |
| compatibility. |
| |
| * The error message printed by `assert' for a failed assertion now includes |
| the name of the program (if using GNU ld) and the name of the calling |
| function (with versions of GCC that support this). |
| |
| * The `psignal' function is now declared in <signal.h>, not <stdio.h>. |
| |
| * The library now includes the <sys/mman.h> header file and memory |
| management functions `mmap', `munmap', `mprotect', `msync', and |
| `madvise', on systems that support those facilities. |
| |
| * The interface for `mcheck' has changed slightly: the function called to |
| abort the program when an allocation inconsistency is detected now takes |
| an argument that indicates the type of failure. The new function |
| `mprobe' lets you request a consistency check for a particular block at |
| any time (checks are normally done only when you call `free' or `realloc' |
| on a block). |
| |
| * It is now possible to easily cross-compile the C library, building on one |
| system a library to run on another machine and/or operating system. All |
| you need to do is set the variable `HOST_CC' in `configparms' to the |
| native compiler for programs to run on the machine you are building on (a |
| few generator programs are used on Unix systems); set `CC' to the |
| cross-compiler. |
| |
| * The new function `fexecve' (only implemented on the GNU system) executes |
| a program file given a file descriptor already open on the file. |
| |
| Version 1.07 |
| |
| * Brendan Kehoe has contributed most of a port to the DEC Alpha |
| running OSF/1 (alpha-dec-osf1). He says it is 75% complete. |
| |
| * You can set the variable `libprefix' in `configparms' to specify a prefix |
| to be prepended to installed library files; this makes it easy to install |
| the GNU C library to be linked as `-lgnuc' or whatever. |
| |
| * The new `stpncpy' is a cross between `stpcpy' and `strncpy': It |
| copies a limited number of characters from a string, and returns the |
| address of the last character written. |
| |
| * You no longer need to check for whether the installed `stddef.h' is |
| compatible with the GNU C library. configure now checks for you. |
| |
| * You can now define a per-stream `fileno' function to convert the |
| stream's cookie into an integral file descriptor. |
| |
| * ``malloc (0)'' no longer returns a null pointer. Instead, it |
| allocates zero bytes of storage, and returns a unique pointer which |
| you can pass to `realloc' or `free'. The behavior is undefined if |
| you dereference this pointer. |
| |
| * The C library now runs on Sony NEWS m68k machines running either |
| NewsOS 3 or NewsOS 4. |
| |
| * The new `syscall' function is a system-dependent primitive function |
| for invoking system calls. It has the canonical behavior on Unix |
| systems, including unreliable return values for some calls (such as |
| `pipe', `fork' and `getppid'). |
| |
| * The error code `EWOULDBLOCK' is now obsolete; it is always defined |
| to `EAGAIN', which is the preferred name. On systems whose kernels |
| use two distinct codes, the C library now translates EWOULDBLOCK to |
| EAGAIN in every system call function. |
| |
| Version 1.06 |
| |
| * The GNU C Library Reference Manual is now distributed with the library. |
| `make dvi' will produce a DVI file of the printed manual. |
| `make info' will produce Info files that you can read on line using C-h i |
| in Emacs or the `info' program. |
| Please send comments on the manual to bug-glibc-manual@gnu.org. |
| |
| * The library now supports SVR4 on i386s (i386-unknown-sysv4). |
| |
| * Brendan Kehoe has contributed a port to Sun SPARCs running Solaris 2. |
| |
| * Jason Merrill has contributed a port to the Sequent Symmetry running |
| Dynix version 3 (i386-sequent-dynix). |
| |
| * The library has been ported to i386s running SCO 3.2.4 (also known as SCO |
| ODT 2.0; i386-unknown-sco3.2.4) or SCO 3.2 (i386-unknown-sco3.2). |
| |
| * New function `memory_warnings' lets you arrange to get warnings when |
| malloc is running out of memory to allocate, like Emacs gives you. |
| |
| * The C library now contains the relocating allocator used in Emacs 19 for |
| its editing buffers. This allocator (ralloc) minimizes allocation |
| overhead and fragmentation by moving allocated regions around whenever it |
| needs to. You always refer to a ralloc'd region with a "handle" (a |
| pointer to a pointer--an object of type `void **'). |
| |
| * There is a new `printf' format: `%m' gives you the string corresponding |
| to the error code in `errno'. |
| |
| * In `scanf' formats, you can now use `%as' or `%a[' to do the normal `%s' |
| or `%[' conversion, but instead of filling in a fixed-sized buffer you |
| pass, the `a' modifier says to fill in a `char **' you pass with a |
| malloc'd string. |
| |
| * The `fnmatch' function supports the new flag bits `FNM_LEADING_DIR' and |
| `FNM_CASEFOLD'. `FNM_LEADING_DIR' lets a pattern like `foo*' match a |
| name like `foo/bar'. `FNM_CASEFOLD' says to ignore case in matching. |
| |
| * `mkstemp' is a traditional Unix function to atomically create and open a |
| uniquely-named temporary file. |
| |
| Version 1.05 |
| |
| * The standard location for the file that says what the local timezone is |
| has changed again. It is now `/usr/local/etc/localtime' (or more |
| precisely, `${prefix}/etc/localtime') rather than `/etc/localtime'. |
| |
| * The distribution no longer contains any files with names longer than 14 |
| characters. |
| |
| * `struct ttyent' has two new flag bits: TTY_TRUSTED and TTY_CONSOLE. |
| These are set by the new `trusted' and `console' keywords in `/etc/ttys'. |
| |
| * New functions `ttyslot' and `syslog' from 4.4 BSD. |
| |
| Version 1.04 |
| |
| * The configuration process has changed quite a bit. The `configure' |
| script is now used just like the configuration scripts for other GNU |
| packages. The `sysdeps' directory hierarchy is much rearranged. |
| The file `INSTALL' explains the new scheme in detail. |
| |
| * The header files no longer need to be processed into ANSI C and |
| traditional C versions. There is just one set of files to install, and |
| it will work with ANSI or old C compilers (including `gcc -traditional'). |
| |
| * Brendan Kehoe and Ian Lance Taylor have ported the library to the |
| MIPS DECStation running Ultrix 4. |
| |
| * The Sun 4 startup code (crt0) can now properly load SunOS 4 shared libraries. |
| Tom Quinn contributed the initial code. The GNU C library can NOT yet be |
| made itself into a shared library. |
| |
| * Yet further improved support for the i386, running 4.3 BSD-like systems |
| (such as Mach 3 with the Unix single-server), or System V. |
| |
| * New function `strncasecmp' to do case-insensitive string comparison |
| with limited length. |
| |
| * New function `strsep' is a reentrant alternative to `strtok'. |
| |
| * New functions `scandir' and `alphasort' for searching directories. |
| |
| * New function `setenv' is a better interface to `putenv'. |
| |
| * Ian Lance Taylor has contributed an implementation of the SVID `ftw' |
| function for traversing a directory tree. |
| |
| * The GNU obstack package is now also part of the C library. |
| The new function `open_obstack_stream' creates a stdio stream that |
| writes onto an obstack; `obstack_printf' and `obstack_vprintf' do |
| formatted output directly to an obstack. |
| |
| * Miscellaneous new functions: reboot, nice, sigaltstack (4.4 BSD only), |
| cfmakeraw, getusershell, getpass, swab, getttyent, seteuid, setegid. |
| |
| * `FNM_FILE_NAME' is another name for `FNM_PATHNAME', used with `fnmatch'. |
| |
| * The new functions `strfry' and `memfrob' do mysterious and wonderful |
| things to your strings. |
| |
| * There are some new test programs: test-fseek, testmb, and testrand. |
| |
| * Some work has been done to begin porting the library to 4.4 BSD and Linux. |
| These ports are not finished, but are a good starting place for really |
| supporting those systems. |
| |
| * `/etc/localtime' is now the standard location for the file that says what |
| the local timezone is, rather than `/usr/local/lib/zoneinfo/localtime'. |
| This follows the general principle that `/etc' is the place for all local |
| configuration files. |
| |
| * The C library header files now use `extern "C"' when used by the C++ |
| compiler, so the C library should now work with C++ code. |
| |
| * The header file <bstring.h> is gone. <string.h> now declares bcopy, |
| bcmp, bzero, and ffs. (Update: nowadays these functions are declared |
| in <strings.h>.) |
| |
| * Mike Haertel (of GNU e?grep and malloc fame) has written a new sorting |
| function which uses the `merge sort' algorithm, and is said to be |
| significantly faster than the old GNU `qsort' function. Merge sort is |
| now the standard `qsort' function. The new algorithm can require a lot |
| of temporary storage; so, the old sorting function is called when the |
| required storage is not available. |
| |
| * The C library now includes Michael Glad's Ultra Fast Crypt, which |
| provides the Unix `crypt' function, plus some other entry points. |
| |
| * The code and header files taken from 4.4 BSD have been updated with the |
| latest files released from Berkeley. |
