It also counts + as the successor of the GNU Library Public License, version 2, hence + the version number 2.1.] + + Preamble + + The licenses for most software are designed to take away your +freedom to share and change it. By contrast, the GNU General Public +Licenses are intended to guarantee your freedom to share and change +free software--to make sure the software is free for all its users. + + This license, the Lesser General Public License, applies to some +specially designated software packages--typically libraries--of the +Free Software Foundation and other authors who decide to use it. You +can use it too, but we suggest you first think carefully about whether +this license or the ordinary General Public License is the better +strategy to use in any particular case, based on the explanations below. + + When we speak of free software, we are referring to freedom of use, +not price. Our General Public Licenses are designed to make sure that +you have the freedom to distribute copies of free software (and charge +for this service if you wish); that you receive source code or can get +it if you want it; that you can change the software and use pieces of +it in new free programs; and that you are informed that you can do +these things. + + To protect your rights, we need to make restrictions that forbid +distributors to deny you these rights or to ask you to surrender these +rights. These restrictions translate to certain responsibilities for +you if you distribute copies of the library or if you modify it. + + For example, if you distribute copies of the library, whether gratis +or for a fee, you must give the recipients all the rights that we gave +you. You must make sure that they, too, receive or can get the source +code. If you link other code with the library, you must provide +complete object files to the recipients, so that they can relink them +with the library after making changes to the library and recompiling +it. And you must show them these terms so they know their rights. + + We protect your rights with a two-step method: (1) we copyright the +library, and (2) we offer you this license, which gives you legal +permission to copy, distribute and/or modify the library. + + To protect each distributor, we want to make it very clear that +there is no warranty for the free library. Also, if the library is +modified by someone else and passed on, the recipients should know +that what they have is not the original version, so that the original +author's reputation will not be affected by problems that might be +introduced by others. + + Finally, software patents pose a constant threat to the existence of +any free program. We wish to make sure that a company cannot +effectively restrict the users of a free program by obtaining a +restrictive license from a patent holder. Therefore, we insist that +any patent license obtained for a version of the library must be +consistent with the full freedom of use specified in this license. + + Most GNU software, including some libraries, is covered by the +ordinary GNU General Public License. This license, the GNU Lesser +General Public License, applies to certain designated libraries, and +is quite different from the ordinary General Public License. We use +this license for certain libraries in order to permit linking those +libraries into non-free programs. + + When a program is linked with a library, whether statically or using +a shared library, the combination of the two is legally speaking a +combined work, a derivative of the original library. The ordinary +General Public License therefore permits such linking only if the +entire combination fits its criteria of freedom. The Lesser General +Public License permits more lax criteria for linking other code with +the library. + + We call this license the "Lesser" General Public License because it +does Less to protect the user's freedom than the ordinary General +Public License. It also provides other free software developers Less +of an advantage over competing non-free programs. These disadvantages +are the reason we use the ordinary General Public License for many +libraries. However, the Lesser license provides advantages in certain +special circumstances. + + For example, on rare occasions, there may be a special need to +encourage the widest possible use of a certain library, so that it becomes +a de-facto standard. To achieve this, non-free programs must be +allowed to use the library. A more frequent case is that a free +library does the same job as widely used non-free libraries. In this +case, there is little to gain by limiting the free library to free +software only, so we use the Lesser General Public License. + + In other cases, permission to use a particular library in non-free +programs enables a greater number of people to use a large body of +free software. For example, permission to use the GNU C Library in +non-free programs enables many more people to use the whole GNU +operating system, as well as its variant, the GNU/Linux operating +system. + + Although the Lesser General Public License is Less protective of the +users' freedom, it does ensure that the user of a program that is +linked with the Library has the freedom and the wherewithal to run +that program using a modified version of the Library. + + The precise terms and conditions for copying, distribution and +modification follow. Pay close attention to the difference between a +"work based on the library" and a "work that uses the library". The +former contains code derived from the library, whereas the latter must +be combined with the library in order to run. + + GNU LESSER GENERAL PUBLIC LICENSE + TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION + + 0. This License Agreement applies to any software library or other +program which contains a notice placed by the copyright holder or +other authorized party saying it may be distributed under the terms of +this Lesser General Public License (also called "this License"). +Each licensee is addressed as "you". + + A "library" means a collection of software functions and/or data +prepared so as to be conveniently linked with application programs +(which use some of those functions and data) to form executables. + + The "Library", below, refers to any such software library or work +which has been distributed under these terms. A "work based on the +Library" means either the Library or any derivative work under +copyright law: that is to say, a work containing the Library or a +portion of it, either verbatim or with modifications and/or translated +straightforwardly into another language. (Hereinafter, translation is +included without limitation in the term "modification".) + + "Source code" for a work means the preferred form of the work for +making modifications to it. For a library, complete source code means +all the source code for all modules it contains, plus any associated +interface definition files, plus the scripts used to control compilation +and installation of the library. + + Activities other than copying, distribution and modification are not +covered by this License; they are outside its scope. The act of +running a program using the Library is not restricted, and output from +such a program is covered only if its contents constitute a work based +on the Library (independent of the use of the Library in a tool for +writing it). Whether that is true depends on what the Library does +and what the program that uses the Library does. + + 1. You may copy and distribute verbatim copies of the Library's +complete source code as you receive it, in any medium, provided that +you conspicuously and appropriately publish on each copy an +appropriate copyright notice and disclaimer of warranty; keep intact +all the notices that refer to this License and to the absence of any +warranty; and distribute a copy of this License along with the +Library. + + You may charge a fee for the physical act of transferring a copy, +and you may at your option offer warranty protection in exchange for a +fee. + + 2. You may modify your copy or copies of the Library or any portion +of it, thus forming a work based on the Library, and copy and +distribute such modifications or work under the terms of Section 1 +above, provided that you also meet all of these conditions: + + a) The modified work must itself be a software library. + + b) You must cause the files modified to carry prominent notices + stating that you changed the files and the date of any change. + + c) You must cause the whole of the work to be licensed at no + charge to all third parties under the terms of this License. + + d) If a facility in the modified Library refers to a function or a + table of data to be supplied by an application program that uses + the facility, other than as an argument passed when the facility + is invoked, then you must make a good faith effort to ensure that, + in the event an application does not supply such function or + table, the facility still operates, and performs whatever part of + its purpose remains meaningful. + + (For example, a function in a library to compute square roots has + a purpose that is entirely well-defined independent of the + application. Therefore, Subsection 2d requires that any + application-supplied function or table used by this function must + be optional: if the application does not supply it, the square + root function must still compute square roots.) + +These requirements apply to the modified work as a whole. If +identifiable sections of that work are not derived from the Library, +and can be reasonably considered independent and separate works in +themselves, then this License, and its terms, do not apply to those +sections when you distribute them as separate works. But when you +distribute the same sections as part of a whole which is a work based +on the Library, the distribution of the whole must be on the terms of +this License, whose permissions for other licensees extend to the +entire whole, and thus to each and every part regardless of who wrote +it. + +Thus, it is not the intent of this section to claim rights or contest +your rights to work written entirely by you; rather, the intent is to +exercise the right to control the distribution of derivative or +collective works based on the Library. + +In addition, mere aggregation of another work not based on the Library +with the Library (or with a work based on the Library) on a volume of +a storage or distribution medium does not bring the other work under +the scope of this License. + + 3. You may opt to apply the terms of the ordinary GNU General Public +License instead of this License to a given copy of the Library. To do +this, you must alter all the notices that refer to this License, so +that they refer to the ordinary GNU General Public License, version 2, +instead of to this License. (If a newer version than version 2 of the +ordinary GNU General Public License has appeared, then you can specify +that version instead if you wish.) Do not make any other change in +these notices. + + Once this change is made in a given copy, it is irreversible for +that copy, so the ordinary GNU General Public License applies to all +subsequent copies and derivative works made from that copy. + + This option is useful when you wish to copy part of the code of +the Library into a program that is not a library. + + 4. You may copy and distribute the Library (or a portion or +derivative of it, under Section 2) in object code or executable form +under the terms of Sections 1 and 2 above provided that you accompany +it with the complete corresponding machine-readable source code, which +must be distributed under the terms of Sections 1 and 2 above on a +medium customarily used for software interchange. + + If distribution of object code is made by offering access to copy +from a designated place, then offering equivalent access to copy the +source code from the same place satisfies the requirement to +distribute the source code, even though third parties are not +compelled to copy the source along with the object code. + + 5. A program that contains no derivative of any portion of the +Library, but is designed to work with the Library by being compiled or +linked with it, is called a "work that uses the Library". Such a +work, in isolation, is not a derivative work of the Library, and +therefore falls outside the scope of this License. + + However, linking a "work that uses the Library" with the Library +creates an executable that is a derivative of the Library (because it +contains portions of the Library), rather than a "work that uses the +library". The executable is therefore covered by this License. +Section 6 states terms for distribution of such executables. + + When a "work that uses the Library" uses material from a header file +that is part of the Library, the object code for the work may be a +derivative work of the Library even though the source code is not. +Whether this is true is especially significant if the work can be +linked without the Library, or if the work is itself a library. The +threshold for this to be true is not precisely defined by law. + + If such an object file uses only numerical parameters, data +structure layouts and accessors, and small macros and small inline +functions (ten lines or less in length), then the use of the object +file is unrestricted, regardless of whether it is legally a derivative +work. (Executables containing this object code plus portions of the +Library will still fall under Section 6.) + + Otherwise, if the work is a derivative of the Library, you may +distribute the object code for the work under the terms of Section 6. +Any executables containing that work also fall under Section 6, +whether or not they are linked directly with the Library itself. + + 6. As an exception to the Sections above, you may also combine or +link a "work that uses the Library" with the Library to produce a +work containing portions of the Library, and distribute that work +under terms of your choice, provided that the terms permit +modification of the work for the customer's own use and reverse +engineering for debugging such modifications. + + You must give prominent notice with each copy of the work that the +Library is used in it and that the Library and its use are covered by +this License. You must supply a copy of this License. If the work +during execution displays copyright notices, you must include the +copyright notice for the Library among them, as well as a reference +directing the user to the copy of this License. Also, you must do one +of these things: + + a) Accompany the work with the complete corresponding + machine-readable source code for the Library including whatever + changes were used in the work (which must be distributed under + Sections 1 and 2 above); and, if the work is an executable linked + with the Library, with the complete machine-readable "work that + uses the Library", as object code and/or source code, so that the + user can modify the Library and then relink to produce a modified + executable containing the modified Library. (It is understood + that the user who changes the contents of definitions files in the + Library will not necessarily be able to recompile the application + to use the modified definitions.) + + b) Use a suitable shared library mechanism for linking with the + Library. A suitable mechanism is one that (1) uses at run time a + copy of the library already present on the user's computer system, + rather than copying library functions into the executable, and (2) + will operate properly with a modified version of the library, if + the user installs one, as long as the modified version is + interface-compatible with the version that the work was made with. + + c) Accompany the work with a written offer, valid for at + least three years, to give the same user the materials + specified in Subsection 6a, above, for a charge no more + than the cost of performing this distribution. + + d) If distribution of the work is made by offering access to copy + from a designated place, offer equivalent access to copy the above + specified materials from the same place. + + e) Verify that the user has already received a copy of these + materials or that you have already sent this user a copy. + + For an executable, the required form of the "work that uses the +Library" must include any data and utility programs needed for +reproducing the executable from it. However, as a special exception, +the materials to be distributed need not include anything that is +normally distributed (in either source or binary form) with the major +components (compiler, kernel, and so on) of the operating system on +which the executable runs, unless that component itself accompanies +the executable. + + It may happen that this requirement contradicts the license +restrictions of other proprietary libraries that do not normally +accompany the operating system. Such a contradiction means you cannot +use both them and the Library together in an executable that you +distribute. + + 7. You may place library facilities that are a work based on the +Library side-by-side in a single library together with other library +facilities not covered by this License, and distribute such a combined +library, provided that the separate distribution of the work based on +the Library and of the other library facilities is otherwise +permitted, and provided that you do these two things: + + a) Accompany the combined library with a copy of the same work + based on the Library, uncombined with any other library + facilities. This must be distributed under the terms of the + Sections above. + + b) Give prominent notice with the combined library of the fact + that part of it is a work based on the Library, and explaining + where to find the accompanying uncombined form of the same work. + + 8. You may not copy, modify, sublicense, link with, or distribute +the Library except as expressly provided under this License. Any +attempt otherwise to copy, modify, sublicense, link with, or +distribute the Library is void, and will automatically terminate your +rights under this License. However, parties who have received copies, +or rights, from you under this License will not have their licenses +terminated so long as such parties remain in full compliance. + + 9. You are not required to accept this License, since you have not +signed it. However, nothing else grants you permission to modify or +distribute the Library or its derivative works. These actions are +prohibited by law if you do not accept this License. Therefore, by +modifying or distributing the Library (or any work based on the +Library), you indicate your acceptance of this License to do so, and +all its terms and conditions for copying, distributing or modifying +the Library or works based on it. + + 10. Each time you redistribute the Library (or any work based on the +Library), the recipient automatically receives a license from the +original licensor to copy, distribute, link with or modify the Library +subject to these terms and conditions. You may not impose any further +restrictions on the recipients' exercise of the rights granted herein. +You are not responsible for enforcing compliance by third parties with +this License. + + 11. If, as a consequence of a court judgment or allegation of patent +infringement or for any other reason (not limited to patent issues), +conditions are imposed on you (whether by court order, agreement or +otherwise) that contradict the conditions of this License, they do not +excuse you from the conditions of this License. If you cannot +distribute so as to satisfy simultaneously your obligations under this +License and any other pertinent obligations, then as a consequence you +may not distribute the Library at all. For example, if a patent +license would not permit royalty-free redistribution of the Library by +all those who receive copies directly or indirectly through you, then +the only way you could satisfy both it and this License would be to +refrain entirely from distribution of the Library. + +If any portion of this section is held invalid or unenforceable under any +particular circumstance, the balance of the section is intended to apply, +and the section as a whole is intended to apply in other circumstances. + +It is not the purpose of this section to induce you to infringe any +patents or other property right claims or to contest validity of any +such claims; this section has the sole purpose of protecting the +integrity of the free software distribution system which is +implemented by public license practices. Many people have made +generous contributions to the wide range of software distributed +through that system in reliance on consistent application of that +system; it is up to the author/donor to decide if he or she is willing +to distribute software through any other system and a licensee cannot +impose that choice. + +This section is intended to make thoroughly clear what is believed to +be a consequence of the rest of this License. + + 12. If the distribution and/or use of the Library is restricted in +certain countries either by patents or by copyrighted interfaces, the +original copyright holder who places the Library under this License may add +an explicit geographical distribution limitation excluding those countries, +so that distribution is permitted only in or among countries not thus +excluded. In such case, this License incorporates the limitation as if +written in the body of this License. + + 13. The Free Software Foundation may publish revised and/or new +versions of the Lesser General Public License from time to time. +Such new versions will be similar in spirit to the present version, +but may differ in detail to address new problems or concerns. + +Each version is given a distinguishing version number. If the Library +specifies a version number of this License which applies to it and +"any later version", you have the option of following the terms and +conditions either of that version or of any later version published by +the Free Software Foundation. If the Library does not specify a +license version number, you may choose any version ever published by +the Free Software Foundation. + + 14. If you wish to incorporate parts of the Library into other free +programs whose distribution conditions are incompatible with these, +write to the author to ask for permission. For software which is +copyrighted by the Free Software Foundation, write to the Free +Software Foundation; we sometimes make exceptions for this. Our +decision will be guided by the two goals of preserving the free status +of all derivatives of our free software and of promoting the sharing +and reuse of software generally. + + NO WARRANTY + + 15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO +WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW. +EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR +OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY +KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE +IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR +PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE +LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME +THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. + + 16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN +WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY +AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU +FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR +CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE +LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING +RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A +FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF +SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH +DAMAGES. + + END OF TERMS AND CONDITIONS + + How to Apply These Terms to Your New Libraries + + If you develop a new library, and you want it to be of the greatest +possible use to the public, we recommend making it free software that +everyone can redistribute and change. You can do so by permitting +redistribution under these terms (or, alternatively, under the terms of the +ordinary General Public License). + + To apply these terms, attach the following notices to the library. It is +safest to attach them to the start of each source file to most effectively +convey the exclusion of warranty; and each file should have at least the +"copyright" line and a pointer to where the full notice is found. + + <one line to give the library's name and a brief idea of what it does.> + Copyright (C) <year> <name of author> + + This library is free software; you can redistribute it and/or + modify it under the terms of the GNU Lesser General Public + License as published by the Free Software Foundation; either + version 2.1 of the License, or (at your option) any later version. + + This library is distributed in the hope that it will be useful, + but WITHOUT ANY WARRANTY; without even the implied warranty of + MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

The following +more-detailed instructions are generic; see the `README' file for +instructions specific to this package. + + The `configure' shell script attempts to guess correct values for +various system-dependent variables used during compilation. It uses +those values to create a `Makefile' in each directory of the package. +It may also create one or more `.h' files containing system-dependent +definitions. Finally, it creates a shell script `config.status' that +you can run in the future to recreate the current configuration, and a +file `config.log' containing compiler output (useful mainly for +debugging `configure'). + + It can also use an optional file (typically called `config.cache' +and enabled with `--cache-file=config.cache' or simply `-C') that saves +the results of its tests to speed up reconfiguring. Caching is +disabled by default to prevent problems with accidental use of stale +cache files. + + If you need to do unusual things to compile the package, please try +to figure out how `configure' could check whether to do them, and mail +diffs or instructions to the address given in the `README' so they can +be considered for the next release. If you are using the cache, and at +some point `config.cache' contains results you don't want to keep, you +may remove or edit it. + + The file `configure.ac' (or `configure.in') is used to create +`configure' by a program called `autoconf'. You need `configure.ac' if +you want to change it or regenerate `configure' using a newer version +of `autoconf'. + +The simplest way to compile this package is: + + 1. `cd' to the directory containing the package's source code and type + `./configure' to configure the package for your system. + + Running `configure' might take a while. While running, it prints + some messages telling which features it is checking for. + + 2. Type `make' to compile the package. + + 3. Optionally, type `make check' to run any self-tests that come with + the package. + + 4. Type `make install' to install the programs and any data files and + documentation. + + 5. You can remove the program binaries and object files from the + source code directory by typing `make clean'. To also remove the + files that `configure' created (so you can compile the package for + a different kind of computer), type `make distclean'. There is + also a `make maintainer-clean' target, but that is intended mainly + for the package's developers. If you use it, you may have to get + all sorts of other programs in order to regenerate files that came + with the distribution. + +Compilers and Options +===================== + +Some systems require unusual options for compilation or linking that the +`configure' script does not know about. Run `./configure --help' for +details on some of the pertinent environment variables. + + You can give `configure' initial values for configuration parameters +by setting variables in the command line or in the environment. Here +is an example: + + ./configure CC=c99 CFLAGS=-g LIBS=-lposix + + *Note Defining Variables::, for more details. + +Compiling For Multiple Architectures +==================================== + +You can compile the package for more than one kind of computer at the +same time, by placing the object files for each architecture in their +own directory. To do this, you can use GNU `make'. `cd' to the +directory where you want the object files and executables to go and run +the `configure' script. `configure' automatically checks for the +source code in the directory that `configure' is in and in `..'. + + With a non-GNU `make', it is safer to compile the package for one +architecture at a time in the source code directory. After you have +installed the package for one architecture, use `make distclean' before +reconfiguring for another architecture. + +Installation Names +================== + +By default, `make install' installs the package's commands under +`/usr/local/bin', include files under `/usr/local/include', etc. You +can specify an installation prefix other than `/usr/local' by giving +`configure' the option `--prefix=PREFIX'. + + You can specify separate installation prefixes for +architecture-specific files and architecture-independent files. If you +pass the option `--exec-prefix=PREFIX' to `configure', the package uses +PREFIX as the prefix for installing programs and libraries. +Documentation and other data files still use the regular prefix. + + In addition, if you use an unusual directory layout you can give +options like `--bindir=DIR' to specify different values for particular +kinds of files. Run `configure --help' for a list of the directories +you can set and what kinds of files go in them. + + If the package supports it, you can cause programs to be installed +with an extra prefix or suffix on their names by giving `configure' the +option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'. + +Optional Features +================= + +Some packages pay attention to `--enable-FEATURE' options to +`configure', where FEATURE indicates an optional part of the package. +They may also pay attention to `--with-PACKAGE' options, where PACKAGE +is something like `gnu-as' or `x' (for the X Window System). The +`README' should mention any `--enable-' and `--with-' options that the +package recognizes. + + For packages that use the X Window System, `configure' can usually +find the X include and library files automatically, but if it doesn't, +you can use the `configure' options `--x-includes=DIR' and +`--x-libraries=DIR' to specify their locations. + +Specifying the System Type +========================== + +There may be some features `configure' cannot figure out automatically, +but needs to determine by the type of machine the package will run on. +Usually, assuming the package is built to be run on the _same_ +architectures, `configure' can figure that out, but if it prints a +message saying it cannot guess the machine type, give it the +`--build=TYPE' option. TYPE can either be a short name for the system +type, such as `sun4', or a canonical name which has the form: + + CPU-COMPANY-SYSTEM + +where SYSTEM can have one of these forms: + + OS KERNEL-OS + + See the file `config.sub' for the possible values of each field. If +`config.sub' isn't included in this package, then this package doesn't +need to know the machine type. + + If you are _building_ compiler tools for cross-compiling, you should +use the option `--target=TYPE' to select the type of system they will +produce code for. + + If you want to _use_ a cross compiler, that generates code for a +platform different from the build platform, you should specify the +"host" platform (i.e., that on which the generated programs will +eventually be run) with `--host=TYPE'. + +Sharing Defaults +================ + +If you want to set default values for `configure' scripts to share, you +can create a site shell script called `config.site' that gives default +values for variables like `CC', `cache_file', and `prefix'. +`configure' looks for `PREFIX/share/config.site' if it exists, then +`PREFIX/etc/config.site' if it exists. Or, you can set the +`CONFIG_SITE' environment variable to the location of the site script. +A warning: not all `configure' scripts look for a site script. + +Defining Variables +================== + +Variables not defined in a site shell script can be set in the +environment passed to `configure'. However, some packages may run +configure again during the build, and the customized values of these +variables may be lost. In order to avoid this problem, you should set +them in the `configure' command line, using `VAR=value'. For example: + + ./configure CC=/usr/local2/bin/gcc + +causes the specified `gcc' to be used as the C compiler (unless it is +overridden in the site shell script). + +Unfortunately, this technique does not work for `CONFIG_SHELL' due to +an Autoconf bug. Until the bug is fixed you can use this workaround: + + CONFIG_SHELL=/bin/bash /bin/bash ./configure CONFIG_SHELL=/bin/bash + +`configure' Invocation +====================== + +`configure' recognizes the following options to control how it operates. + +`--help' +`-h' + Print a summary of the options to `configure', and exit. + +`--version' +`-V' + Print the version of Autoconf used to generate the `configure' + script, and exit. + +`--cache-file=FILE' + Enable the cache: use and save the results of the tests in FILE, + traditionally `config.cache'. FILE defaults to `/dev/null' to + disable caching. + +`--config-cache' +`-C' + Alias for `--cache-file=config.cache'. + +`--quiet' +`--silent' +`-q' + Do not print messages saying which checks are being made. To + suppress all normal output, redirect it to `/dev/null' (any error + messages will still be shown). + +`--srcdir=DIR' + Look for the package's source code in directory DIR. Usually + `configure' can determine that directory automatically. + +`configure' also accepts some other, not widely useful, options. Run +`configure --help' for more details. +

It also counts + as the successor of the GNU Library Public License, version 2, hence + the version number 2.1.] + + Preamble + + The licenses for most software are designed to take away your +freedom to share and change it. By contrast, the GNU General Public +Licenses are intended to guarantee your freedom to share and change +free software--to make sure the software is free for all its users. + + This license, the Lesser General Public License, applies to some +specially designated software packages--typically libraries--of the +Free Software Foundation and other authors who decide to use it. You +can use it too, but we suggest you first think carefully about whether +this license or the ordinary General Public License is the better +strategy to use in any particular case, based on the explanations below. + + When we speak of free software, we are referring to freedom of use, +not price. Our General Public Licenses are designed to make sure that +you have the freedom to distribute copies of free software (and charge +for this service if you wish); that you receive source code or can get +it if you want it; that you can change the software and use pieces of +it in new free programs; and that you are informed that you can do +these things. + + To protect your rights, we need to make restrictions that forbid +distributors to deny you these rights or to ask you to surrender these +rights. These restrictions translate to certain responsibilities for +you if you distribute copies of the library or if you modify it. + + For example, if you distribute copies of the library, whether gratis +or for a fee, you must give the recipients all the rights that we gave +you. You must make sure that they, too, receive or can get the source +code. If you link other code with the library, you must provide +complete object files to the recipients, so that they can relink them +with the library after making changes to the library and recompiling +it. And you must show them these terms so they know their rights. + + We protect your rights with a two-step method: (1) we copyright the +library, and (2) we offer you this license, which gives you legal +permission to copy, distribute and/or modify the library. + + To protect each distributor, we want to make it very clear that +there is no warranty for the free library. Also, if the library is +modified by someone else and passed on, the recipients should know +that what they have is not the original version, so that the original +author's reputation will not be affected by problems that might be +introduced by others. + + Finally, software patents pose a constant threat to the existence of +any free program. We wish to make sure that a company cannot +effectively restrict the users of a free program by obtaining a +restrictive license from a patent holder. Therefore, we insist that +any patent license obtained for a version of the library must be +consistent with the full freedom of use specified in this license. + + Most GNU software, including some libraries, is covered by the +ordinary GNU General Public License. This license, the GNU Lesser +General Public License, applies to certain designated libraries, and +is quite different from the ordinary General Public License. We use +this license for certain libraries in order to permit linking those +libraries into non-free programs. + + When a program is linked with a library, whether statically or using +a shared library, the combination of the two is legally speaking a +combined work, a derivative of the original library. The ordinary +General Public License therefore permits such linking only if the +entire combination fits its criteria of freedom. The Lesser General +Public License permits more lax criteria for linking other code with +the library. + + We call this license the "Lesser" General Public License because it +does Less to protect the user's freedom than the ordinary General +Public License. It also provides other free software developers Less +of an advantage over competing non-free programs. These disadvantages +are the reason we use the ordinary General Public License for many +libraries. However, the Lesser license provides advantages in certain +special circumstances. + + For example, on rare occasions, there may be a special need to +encourage the widest possible use of a certain library, so that it becomes +a de-facto standard. To achieve this, non-free programs must be +allowed to use the library. A more frequent case is that a free +library does the same job as widely used non-free libraries. In this +case, there is little to gain by limiting the free library to free +software only, so we use the Lesser General Public License. + + In other cases, permission to use a particular library in non-free +programs enables a greater number of people to use a large body of +free software. For example, permission to use the GNU C Library in +non-free programs enables many more people to use the whole GNU +operating system, as well as its variant, the GNU/Linux operating +system. + + Although the Lesser General Public License is Less protective of the +users' freedom, it does ensure that the user of a program that is +linked with the Library has the freedom and the wherewithal to run +that program using a modified version of the Library. + + The precise terms and conditions for copying, distribution and +modification follow. Pay close attention to the difference between a +"work based on the library" and a "work that uses the library". The +former contains code derived from the library, whereas the latter must +be combined with the library in order to run. + + GNU LESSER GENERAL PUBLIC LICENSE + TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION + + 0. This License Agreement applies to any software library or other +program which contains a notice placed by the copyright holder or +other authorized party saying it may be distributed under the terms of +this Lesser General Public License (also called "this License"). +Each licensee is addressed as "you". + + A "library" means a collection of software functions and/or data +prepared so as to be conveniently linked with application programs +(which use some of those functions and data) to form executables. + + The "Library", below, refers to any such software library or work +which has been distributed under these terms. A "work based on the +Library" means either the Library or any derivative work under +copyright law: that is to say, a work containing the Library or a +portion of it, either verbatim or with modifications and/or translated +straightforwardly into another language. (Hereinafter, translation is +included without limitation in the term "modification".) + + "Source code" for a work means the preferred form of the work for +making modifications to it. For a library, complete source code means +all the source code for all modules it contains, plus any associated +interface definition files, plus the scripts used to control compilation +and installation of the library. + + Activities other than copying, distribution and modification are not +covered by this License; they are outside its scope. The act of +running a program using the Library is not restricted, and output from +such a program is covered only if its contents constitute a work based +on the Library (independent of the use of the Library in a tool for +writing it). Whether that is true depends on what the Library does +and what the program that uses the Library does. + + 1. You may copy and distribute verbatim copies of the Library's +complete source code as you receive it, in any medium, provided that +you conspicuously and appropriately publish on each copy an +appropriate copyright notice and disclaimer of warranty; keep intact +all the notices that refer to this License and to the absence of any +warranty; and distribute a copy of this License along with the +Library. + + You may charge a fee for the physical act of transferring a copy, +and you may at your option offer warranty protection in exchange for a +fee. + + 2. You may modify your copy or copies of the Library or any portion +of it, thus forming a work based on the Library, and copy and +distribute such modifications or work under the terms of Section 1 +above, provided that you also meet all of these conditions: + + a) The modified work must itself be a software library. + + b) You must cause the files modified to carry prominent notices + stating that you changed the files and the date of any change. + + c) You must cause the whole of the work to be licensed at no + charge to all third parties under the terms of this License. + + d) If a facility in the modified Library refers to a function or a + table of data to be supplied by an application program that uses + the facility, other than as an argument passed when the facility + is invoked, then you must make a good faith effort to ensure that, + in the event an application does not supply such function or + table, the facility still operates, and performs whatever part of + its purpose remains meaningful. + + (For example, a function in a library to compute square roots has + a purpose that is entirely well-defined independent of the + application. Therefore, Subsection 2d requires that any + application-supplied function or table used by this function must + be optional: if the application does not supply it, the square + root function must still compute square roots.) + +These requirements apply to the modified work as a whole. If +identifiable sections of that work are not derived from the Library, +and can be reasonably considered independent and separate works in +themselves, then this License, and its terms, do not apply to those +sections when you distribute them as separate works. But when you +distribute the same sections as part of a whole which is a work based +on the Library, the distribution of the whole must be on the terms of +this License, whose permissions for other licensees extend to the +entire whole, and thus to each and every part regardless of who wrote +it. + +Thus, it is not the intent of this section to claim rights or contest +your rights to work written entirely by you; rather, the intent is to +exercise the right to control the distribution of derivative or +collective works based on the Library. + +In addition, mere aggregation of another work not based on the Library +with the Library (or with a work based on the Library) on a volume of +a storage or distribution medium does not bring the other work under +the scope of this License. + + 3. You may opt to apply the terms of the ordinary GNU General Public +License instead of this License to a given copy of the Library. To do +this, you must alter all the notices that refer to this License, so +that they refer to the ordinary GNU General Public License, version 2, +instead of to this License. (If a newer version than version 2 of the +ordinary GNU General Public License has appeared, then you can specify +that version instead if you wish.) Do not make any other change in +these notices. + + Once this change is made in a given copy, it is irreversible for +that copy, so the ordinary GNU General Public License applies to all +subsequent copies and derivative works made from that copy. + + This option is useful when you wish to copy part of the code of +the Library into a program that is not a library. + + 4. You may copy and distribute the Library (or a portion or +derivative of it, under Section 2) in object code or executable form +under the terms of Sections 1 and 2 above provided that you accompany +it with the complete corresponding machine-readable source code, which +must be distributed under the terms of Sections 1 and 2 above on a +medium customarily used for software interchange. + + If distribution of object code is made by offering access to copy +from a designated place, then offering equivalent access to copy the +source code from the same place satisfies the requirement to +distribute the source code, even though third parties are not +compelled to copy the source along with the object code. + + 5. A program that contains no derivative of any portion of the +Library, but is designed to work with the Library by being compiled or +linked with it, is called a "work that uses the Library". Such a +work, in isolation, is not a derivative work of the Library, and +therefore falls outside the scope of this License. + + However, linking a "work that uses the Library" with the Library +creates an executable that is a derivative of the Library (because it +contains portions of the Library), rather than a "work that uses the +library". The executable is therefore covered by this License. +Section 6 states terms for distribution of such executables. + + When a "work that uses the Library" uses material from a header file +that is part of the Library, the object code for the work may be a +derivative work of the Library even though the source code is not. +Whether this is true is especially significant if the work can be +linked without the Library, or if the work is itself a library. The +threshold for this to be true is not precisely defined by law. + + If such an object file uses only numerical parameters, data +structure layouts and accessors, and small macros and small inline +functions (ten lines or less in length), then the use of the object +file is unrestricted, regardless of whether it is legally a derivative +work. (Executables containing this object code plus portions of the +Library will still fall under Section 6.) + + Otherwise, if the work is a derivative of the Library, you may +distribute the object code for the work under the terms of Section 6. +Any executables containing that work also fall under Section 6, +whether or not they are linked directly with the Library itself. + + 6. As an exception to the Sections above, you may also combine or +link a "work that uses the Library" with the Library to produce a +work containing portions of the Library, and distribute that work +under terms of your choice, provided that the terms permit +modification of the work for the customer's own use and reverse +engineering for debugging such modifications. + + You must give prominent notice with each copy of the work that the +Library is used in it and that the Library and its use are covered by +this License. You must supply a copy of this License. If the work +during execution displays copyright notices, you must include the +copyright notice for the Library among them, as well as a reference +directing the user to the copy of this License. Also, you must do one +of these things: + + a) Accompany the work with the complete corresponding + machine-readable source code for the Library including whatever + changes were used in the work (which must be distributed under + Sections 1 and 2 above); and, if the work is an executable linked + with the Library, with the complete machine-readable "work that + uses the Library", as object code and/or source code, so that the + user can modify the Library and then relink to produce a modified + executable containing the modified Library. (It is understood + that the user who changes the contents of definitions files in the + Library will not necessarily be able to recompile the application + to use the modified definitions.) + + b) Use a suitable shared library mechanism for linking with the + Library. A suitable mechanism is one that (1) uses at run time a + copy of the library already present on the user's computer system, + rather than copying library functions into the executable, and (2) + will operate properly with a modified version of the library, if + the user installs one, as long as the modified version is + interface-compatible with the version that the work was made with. + + c) Accompany the work with a written offer, valid for at + least three years, to give the same user the materials + specified in Subsection 6a, above, for a charge no more + than the cost of performing this distribution. + + d) If distribution of the work is made by offering access to copy + from a designated place, offer equivalent access to copy the above + specified materials from the same place. + + e) Verify that the user has already received a copy of these + materials or that you have already sent this user a copy. + + For an executable, the required form of the "work that uses the +Library" must include any data and utility programs needed for +reproducing the executable from it. However, as a special exception, +the materials to be distributed need not include anything that is +normally distributed (in either source or binary form) with the major +components (compiler, kernel, and so on) of the operating system on +which the executable runs, unless that component itself accompanies +the executable. + + It may happen that this requirement contradicts the license +restrictions of other proprietary libraries that do not normally +accompany the operating system. Such a contradiction means you cannot +use both them and the Library together in an executable that you +distribute. + + 7. You may place library facilities that are a work based on the +Library side-by-side in a single library together with other library +facilities not covered by this License, and distribute such a combined +library, provided that the separate distribution of the work based on +the Library and of the other library facilities is otherwise +permitted, and provided that you do these two things: + + a) Accompany the combined library with a copy of the same work + based on the Library, uncombined with any other library + facilities. This must be distributed under the terms of the + Sections above. + + b) Give prominent notice with the combined library of the fact + that part of it is a work based on the Library, and explaining + where to find the accompanying uncombined form of the same work. + + 8. You may not copy, modify, sublicense, link with, or distribute +the Library except as expressly provided under this License. Any +attempt otherwise to copy, modify, sublicense, link with, or +distribute the Library is void, and will automatically terminate your +rights under this License. However, parties who have received copies, +or rights, from you under this License will not have their licenses +terminated so long as such parties remain in full compliance. + + 9. You are not required to accept this License, since you have not +signed it. However, nothing else grants you permission to modify or +distribute the Library or its derivative works. These actions are +prohibited by law if you do not accept this License. Therefore, by +modifying or distributing the Library (or any work based on the +Library), you indicate your acceptance of this License to do so, and +all its terms and conditions for copying, distributing or modifying +the Library or works based on it. + + 10. Each time you redistribute the Library (or any work based on the +Library), the recipient automatically receives a license from the +original licensor to copy, distribute, link with or modify the Library +subject to these terms and conditions. You may not impose any further +restrictions on the recipients' exercise of the rights granted herein. +You are not responsible for enforcing compliance by third parties with +this License. + + 11. If, as a consequence of a court judgment or allegation of patent +infringement or for any other reason (not limited to patent issues), +conditions are imposed on you (whether by court order, agreement or +otherwise) that contradict the conditions of this License, they do not +excuse you from the conditions of this License. If you cannot +distribute so as to satisfy simultaneously your obligations under this +License and any other pertinent obligations, then as a consequence you +may not distribute the Library at all. For example, if a patent +license would not permit royalty-free redistribution of the Library by +all those who receive copies directly or indirectly through you, then +the only way you could satisfy both it and this License would be to +refrain entirely from distribution of the Library. + +If any portion of this section is held invalid or unenforceable under any +particular circumstance, the balance of the section is intended to apply, +and the section as a whole is intended to apply in other circumstances. + +It is not the purpose of this section to induce you to infringe any +patents or other property right claims or to contest validity of any +such claims; this section has the sole purpose of protecting the +integrity of the free software distribution system which is +implemented by public license practices. Many people have made +generous contributions to the wide range of software distributed +through that system in reliance on consistent application of that +system; it is up to the author/donor to decide if he or she is willing +to distribute software through any other system and a licensee cannot +impose that choice. + +This section is intended to make thoroughly clear what is believed to +be a consequence of the rest of this License. + + 12. If the distribution and/or use of the Library is restricted in +certain countries either by patents or by copyrighted interfaces, the +original copyright holder who places the Library under this License may add +an explicit geographical distribution limitation excluding those countries, +so that distribution is permitted only in or among countries not thus +excluded. In such case, this License incorporates the limitation as if +written in the body of this License. + + 13. The Free Software Foundation may publish revised and/or new +versions of the Lesser General Public License from time to time. +Such new versions will be similar in spirit to the present version, +but may differ in detail to address new problems or concerns. + +Each version is given a distinguishing version number. If the Library +specifies a version number of this License which applies to it and +"any later version", you have the option of following the terms and +conditions either of that version or of any later version published by +the Free Software Foundation. If the Library does not specify a +license version number, you may choose any version ever published by +the Free Software Foundation. + + 14. If you wish to incorporate parts of the Library into other free +programs whose distribution conditions are incompatible with these, +write to the author to ask for permission. For software which is +copyrighted by the Free Software Foundation, write to the Free +Software Foundation; we sometimes make exceptions for this. Our +decision will be guided by the two goals of preserving the free status +of all derivatives of our free software and of promoting the sharing +and reuse of software generally. + + NO WARRANTY + + 15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO +WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW. +EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR +OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY +KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE +IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR +PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE +LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME +THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. + + 16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN +WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY +AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU +FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR +CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE +LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING +RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A +FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF +SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH +DAMAGES. + + END OF TERMS AND CONDITIONS + + How to Apply These Terms to Your New Libraries + + If you develop a new library, and you want it to be of the greatest +possible use to the public, we recommend making it free software that +everyone can redistribute and change.

It is +safest to attach them to the start of each source file to most effectively +convey the exclusion of warranty; and each file should have at least the +"copyright" line and a pointer to where the full notice is found. + + <one line to give the library's name and a brief idea of what it does.> + Copyright (C) <year> <name of author> + + This library is free software; you can redistribute it and/or + modify it under the terms of the GNU Lesser General Public + License as published by the Free Software Foundation; either + version 2.1 of the License, or (at your option) any later version. + + This library is distributed in the hope that it will be useful, + but WITHOUT ANY WARRANTY; without even the implied warranty of + MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

@@ -0,0 +1,94 @@ +PORTING LIBUSB TO OTHER PLATFORMS + +Introduction +============ + +This document is aimed at developers wishing to port libusb to unsupported +platforms. I believe the libusb API is OS-independent, so by supporting +multiple operating systems we pave the way for cross-platform USB device +drivers. + +Implementation-wise, the basic idea is that you provide an interface to +libusb's internal "backend" API, which performs the appropriate operations on +your target platform. + +In terms of USB I/O, your backend provides functionality to submit +asynchronous transfers (synchronous transfers are implemented in the higher +layers, based on the async interface). Your backend must also provide +functionality to cancel those transfers. + +Your backend must also provide an event handling function to "reap" ongoing +transfers and process their results. + +The backend must also provide standard functions for other USB operations, +e.g. setting configuration, obtaining descriptors, etc. + + +File descriptors for I/O polling +================================ + +For libusb to work, your event handling function obviously needs to be called +at various points in time. Your backend must provide a set of file descriptors +which libusb and its users can pass to poll() or select() to determine when +it is time to call the event handling function. + +On Linux, this is easy: the usbfs kernel interface exposes a file descriptor +which can be passed to poll(). If something similar is not true for your +platform, you can emulate this using an internal library thread to reap I/O as +necessary, and a pipe() with the main library to raise events. The file +descriptor of the pipe can then be provided to libusb as an event source. + + +Interface semantics and documentation +===================================== + +Documentation of the backend interface can be found in libusbi.h inside the +usbi_os_backend structure definition. + +Your implementations of these functions will need to call various internal +libusb functions, prefixed with "usbi_". Documentation for these functions +can be found in the .c files where they are implemented. + +You probably want to skim over *all* the documentation before starting your +implementation. For example, you probably need to allocate and store private +OS-specific data for device handles, but the documentation for the mechanism +for doing so is probably not the first thing you will see. + +The Linux backend acts as a good example - view it as a reference +implementation which you should try to match the behaviour of. + + +Getting started +=============== + +1. Modify configure.ac to detect your platform appropriately (see the OS_LINUX +stuff for an example). + +2. Implement your backend in the libusb/os/ directory, modifying +libusb/os/Makefile.am appropriately. + +3. Add preprocessor logic to the top of libusb/core.c to statically assign the +right usbi_backend for your platform. + +4. Produce and test your implementation. + +5. Send your implementation to libusb-devel mailing list. + + +Implementation difficulties? Questions? +======================================= + +If you encounter difficulties porting libusb to your platform, please raise +these issues on the libusb-devel mailing list. Where possible and sensible, I +am interested in solving problems preventing libusb from operating on other +platforms. + +The libusb-devel mailing list is also a good place to ask questions and +make suggestions about the internal API. Hopefully we can produce some +better documentation based on your questions and other input. + +You are encouraged to get involved in the process; if the library needs +some infrastructure additions/modifications to better support your platform, +you are encouraged to make such changes (in cleanly distinct patch +submissions). Even if you do not make such changes yourself, please do raise +the issues on the mailing list at the very minimum.

Download the latest NDK from: + http://developer.android.com/tools/sdk/ndk/index.html + + 2. Extract the NDK. + + 3. Open a shell and make sure there exist an NDK global variable + set to the directory where you extracted the NDK. + + 4. Change directory to libusb's "android/jni" + + 5. Run "$NDK/ndk-build". + +The libusb library, examples and tests can then be found in: + "android/libs/$ARCH" + +Where $ARCH is one of: + armeabi + armeabi-v7a + mips + mips64 + x86 + x86_64 + +Installing: +----------- + +If you wish to use libusb from native code in own Android application +then you should add the following line to your Android.mk file: + + include $(PATH_TO_LIBUSB_SRC)/android/jni/libusb.mk + +You will then need to add the following lines to the build +configuration for each native binary which uses libusb: + + LOCAL_C_INCLUDES += $(LIBUSB_ROOT_ABS) + LOCAL_SHARED_LIBRARIES += libusb1.0 + +The Android build system will then correctly include libusb in the +application package (APK) file, provided ndk-build is invoked before +the package is built. + + +For a rooted device it is possible to install libusb into the system +image of a running device: + + 1. Enable ADB on the device. + + 2. Connect the device to a machine running ADB. + + 3. Execute the following commands on the machine + running ADB: + + # Make the system partition writable + adb shell su -c "mount -o remount,rw /system" + + # Install libusb + adb push obj/local/armeabi/libusb1.0.so /sdcard/ + adb shell su -c "cat > /system/lib/libusb1.0.so < /sdcard/libusb1.0.so" + adb shell rm /sdcard/libusb1.0.so + + # Install the samples and tests + for B in listdevs fxload xusb sam3u_benchmark hotplugtest stress + do + adb push "obj/local/armeabi/$B" /sdcard/ + adb shell su -c "cat > /system/bin/$B < /sdcard/$B" + adb shell su -c "chmod 0755 /system/bin/$B" + adb shell rm "/sdcard/$B" + done + + # Make the system partition read only again + adb shell su -c "mount -o remount,ro /system" + + # Run listdevs to + adb shell su -c "listdevs" + + 4. If your device only has a single OTG port then ADB can generally + be switched to using Wifi with the following commands when connected + via USB: + + adb shell netcfg + # Note the wifi IP address of the phone + adb tcpip 5555 + # Use the IP address from netcfg + adb connect 192.168.1.123:5555 + +Runtime Permissions: +-------------------- + +The default system configuration on most Android device will not allow +access to USB devices. There are several options for changing this. + +If you have control of the system image then you can modify the +ueventd.rc used in the image to change the permissions on +/dev/bus/usb/*/*. If using this approach then it is advisable to +create a new Android permission to protect access to these files. +It is not advisable to give all applications read and write permissions +to these files. + +For rooted devices the code using libusb could be executed as root +using the "su" command. An alternative would be to use the "su" command +to change the permissions on the appropriate /dev/bus/usb/ files. + +Users have reported success in using android.hardware.usb.UsbManager +to request permission to use the UsbDevice and then opening the +device. The difficulties in this method is that there is no guarantee +that it will continue to work in the future Android versions, it +requires invoking Java APIs and running code to match each +android.hardware.usb.UsbDevice to a libusb_device.

For more info, see the + * <a href="http://libusb.info">libusb homepage</a>. + * + * This documentation is aimed at application developers wishing to + * communicate with USB peripherals from their own software. After reviewing + * this documentation, feedback and questions can be sent to the + * <a href="http://mailing-list.libusb.info">libusb-devel mailing list</a>. + * + * This documentation assumes knowledge of how to operate USB devices from + * a software standpoint (descriptors, configurations, interfaces, endpoints, + * control/bulk/interrupt/isochronous transfers, etc). Full information + * can be found in the <a href="http://www.usb.org/developers/docs/">USB 3.0 + * Specification</a> which is available for free download. You can probably + * find less verbose introductions by searching the web. + * + * \section API Application Programming Interface (API) + * + * See the \ref libusb_api page for a complete list of the libusb functions. + * + * \section features Library features + * + * - All transfer types supported (control/bulk/interrupt/isochronous) + * - 2 transfer interfaces: + * -# Synchronous (simple) + * -# Asynchronous (more complicated, but more powerful) + * - Thread safe (although the asynchronous interface means that you + * usually won't need to thread) + * - Lightweight with lean API + * - Compatible with libusb-0.1 through the libusb-compat-0.1 translation layer + * - Hotplug support (on some platforms). See \ref libusb_hotplug. + * + * \section gettingstarted Getting Started + * + * To begin reading the API documentation, start with the Modules page which + * links to the different categories of libusb's functionality. + * + * One decision you will have to make is whether to use the synchronous + * or the asynchronous data transfer interface. The \ref libusb_io documentation + * provides some insight into this topic. + * + * Some example programs can be found in the libusb source distribution under + * the "examples" subdirectory. The libusb homepage includes a list of + * real-life project examples which use libusb. + * + * \section errorhandling Error handling + * + * libusb functions typically return 0 on success or a negative error code + * on failure. These negative error codes relate to LIBUSB_ERROR constants + * which are listed on the \ref libusb_misc "miscellaneous" documentation page. + * + * \section msglog Debug message logging + * + * libusb uses stderr for all logging. By default, logging is set to NONE, + * which means that no output will be produced. However, unless the library + * has been compiled with logging disabled, then any application calls to + * libusb_set_debug(), or the setting of the environmental variable + * LIBUSB_DEBUG outside of the application, can result in logging being + * produced. Your application should therefore not close stderr, but instead + * direct it to the null device if its output is undesirable. + * + * The libusb_set_debug() function can be used to enable logging of certain + * messages. Under standard configuration, libusb doesn't really log much + * so you are advised to use this function to enable all error/warning/ + * informational messages. It will help debug problems with your software. + * + * The logged messages are unstructured. There is no one-to-one correspondence + * between messages being logged and success or failure return codes from + * libusb functions. There is no format to the messages, so you should not + * try to capture or parse them. They are not and will not be localized. + * These messages are not intended to being passed to your application user; + * instead, you should interpret the error codes returned from libusb functions + * and provide appropriate notification to the user. The messages are simply + * there to aid you as a programmer, and if you're confused because you're + * getting a strange error code from a libusb function, enabling message + * logging may give you a suitable explanation. + * + * The LIBUSB_DEBUG environment variable can be used to enable message logging + * at run-time. This environment variable should be set to a log level number, + * which is interpreted the same as the libusb_set_debug() parameter. When this + * environment variable is set, the message logging verbosity level is fixed + * and libusb_set_debug() effectively does nothing. + * + * libusb can be compiled without any logging functions, useful for embedded + * systems. In this case, libusb_set_debug() and the LIBUSB_DEBUG environment + * variable have no effects. + * + * libusb can also be compiled with verbose debugging messages always. When + * the library is compiled in this way, all messages of all verbosities are + * always logged. libusb_set_debug() and the LIBUSB_DEBUG environment variable + * have no effects. + * + * \section remarks Other remarks + * + * libusb does have imperfections. The \ref libusb_caveats "caveats" page attempts + * to document these. + */ + +/** + * \page libusb_caveats Caveats + * + * \section devresets Device resets + * + * The libusb_reset_device() function allows you to reset a device. If your + * program has to call such a function, it should obviously be aware that + * the reset will cause device state to change (e.g. register values may be + * reset). + * + * The problem is that any other program could reset the device your program + * is working with, at any time. libusb does not offer a mechanism to inform + * you when this has happened, so if someone else resets your device it will + * not be clear to your own program why the device state has changed. + * + * Ultimately, this is a limitation of writing drivers in userspace. + * Separation from the USB stack in the underlying kernel makes it difficult + * for the operating system to deliver such notifications to your program. + * The Linux kernel USB stack allows such reset notifications to be delivered + * to in-kernel USB drivers, but it is not clear how such notifications could + * be delivered to second-class drivers that live in userspace. + * + * \section blockonly Blocking-only functionality + * + * The functionality listed below is only available through synchronous, + * blocking functions. There are no asynchronous/non-blocking alternatives, + * and no clear ways of implementing these. + * + * - Configuration activation (libusb_set_configuration()) + * - Interface/alternate setting activation (libusb_set_interface_alt_setting()) + * - Releasing of interfaces (libusb_release_interface()) + * - Clearing of halt/stall condition (libusb_clear_halt()) + * - Device resets (libusb_reset_device()) + * + * \section configsel Configuration selection and handling + * + * When libusb presents a device handle to an application, there is a chance + * that the corresponding device may be in unconfigured state. For devices + * with multiple configurations, there is also a chance that the configuration + * currently selected is not the one that the application wants to use. + * + * The obvious solution is to add a call to libusb_set_configuration() early + * on during your device initialization routines, but there are caveats to + * be aware of: + * -# If the device is already in the desired configuration, calling + * libusb_set_configuration() using the same configuration value will cause + * a lightweight device reset. This may not be desirable behaviour. + * -# In the case where the desired configuration is already active, libusb + * may not even be able to perform a lightweight device reset. For example, + * take my USB keyboard with fingerprint reader: I'm interested in driving + * the fingerprint reader interface through libusb, but the kernel's + * USB-HID driver will almost always have claimed the keyboard interface. + * Because the kernel has claimed an interface, it is not even possible to + * perform the lightweight device reset, so libusb_set_configuration() will + * fail. (Luckily the device in question only has a single configuration.) + * -# libusb will be unable to set a configuration if other programs or + * drivers have claimed interfaces. In particular, this means that kernel + * drivers must be detached from all the interfaces before + * libusb_set_configuration() may succeed. + * + * One solution to some of the above problems is to consider the currently + * active configuration. If the configuration we want is already active, then + * we don't have to select any configuration: +\code +cfg = -1; +libusb_get_configuration(dev, &cfg); +if (cfg != desired) + libusb_set_configuration(dev, desired); +\endcode + * + * This is probably suitable for most scenarios, but is inherently racy: + * another application or driver may change the selected configuration + * <em>after</em> the libusb_get_configuration() call. + * + * Even in cases where libusb_set_configuration() succeeds, consider that other + * applications or drivers may change configuration after your application + * calls libusb_set_configuration(). + * + * One possible way to lock your device into a specific configuration is as + * follows: + * -# Set the desired configuration (or use the logic above to realise that + * it is already in the desired configuration) + * -# Claim the interface that you wish to use + * -# Check that the currently active configuration is the one that you want + * to use. + * + * The above method works because once an interface is claimed, no application + * or driver is able to select another configuration. + * + * \section earlycomp Early transfer completion + * + * NOTE: This section is currently Linux-centric. I am not sure if any of these + * considerations apply to Darwin or other platforms. + * + * When a transfer completes early (i.e. when less data is received/sent in + * any one packet than the transfer buffer allows for) then libusb is designed + * to terminate the transfer immediately, not transferring or receiving any + * more data unless other transfers have been queued by the user. + * + * On legacy platforms, libusb is unable to do this in all situations. After + * the incomplete packet occurs, "surplus" data may be transferred. For recent + * versions of libusb, this information is kept (the data length of the + * transfer is updated) and, for device-to-host transfers, any surplus data was + * added to the buffer. Still, this is not a nice solution because it loses the + * information about the end of the short packet, and the user probably wanted + * that surplus data to arrive in the next logical transfer. + * + * + * \section zlp Zero length packets + * + * - libusb is able to send a packet of zero length to an endpoint simply by + * submitting a transfer of zero length. + * - The \ref libusb_transfer_flags::LIBUSB_TRANSFER_ADD_ZERO_PACKET + * "LIBUSB_TRANSFER_ADD_ZERO_PACKET" flag is currently only supported on Linux. + */ + +/** + * \page libusb_contexts Contexts + * + * It is possible that libusb may be used simultaneously from two independent + * libraries linked into the same executable. For example, if your application + * has a plugin-like system which allows the user to dynamically load a range + * of modules into your program, it is feasible that two independently + * developed modules may both use libusb. + * + * libusb is written to allow for these multiple user scenarios. The two + * "instances" of libusb will not interfere: libusb_set_debug() calls + * from one user will not affect the same settings for other users, other + * users can continue using libusb after one of them calls libusb_exit(), etc. + * + * This is made possible through libusb's <em>context</em> concept. When you + * call libusb_init(), you are (optionally) given a context. You can then pass + * this context pointer back into future libusb functions. + * + * In order to keep things simple for more simplistic applications, it is + * legal to pass NULL to all functions requiring a context pointer (as long as + * you're sure no other code will attempt to use libusb from the same process). + * When you pass NULL, the default context will be used. The default context + * is created the first time a process calls libusb_init() when no other + * context is alive. Contexts are destroyed during libusb_exit(). + * + * The default context is reference-counted and can be shared. That means that + * if libusb_init(NULL) is called twice within the same process, the two + * users end up sharing the same context. The deinitialization and freeing of + * the default context will only happen when the last user calls libusb_exit(). + * In other words, the default context is created and initialized when its + * reference count goes from 0 to 1, and is deinitialized and destroyed when + * its reference count goes from 1 to 0. + * + * You may be wondering why only a subset of libusb functions require a + * context pointer in their function definition. Internally, libusb stores + * context pointers in other objects (e.g. libusb_device instances) and hence + * can infer the context from those objects. + */ + + /** + * \page libusb_api Application Programming Interface + * + * This is the complete list of libusb functions, structures and + * enumerations in alphabetical order. + * + * \section Functions + * -

A device represents a USB device that + * is currently or was previously connected to the system. Using a reference + * to a device, you can determine certain information about the device (e.g. + * you can read the descriptor data). + * + * The libusb_get_device_list() function can be used to obtain a list of + * devices currently connected to the system. This is known as device + * discovery. + * + * Just because you have a reference to a device does not mean it is + * necessarily usable. The device may have been unplugged, you may not have + * permission to operate such device, or another program or driver may be + * using the device. + * + * When you've found a device that you'd like to operate, you must ask + * libusb to open the device using the libusb_open() function. Assuming + * success, libusb then returns you a <em>device handle</em> + * (a \ref libusb_device_handle pointer). All "real" I/O operations then + * operate on the handle rather than the original device pointer. + * + * \section devref Device discovery and reference counting + * + * Device discovery (i.e. calling libusb_get_device_list()) returns a + * freshly-allocated list of devices. The list itself must be freed when + * you are done with it. libusb also needs to know when it is OK to free + * the contents of the list - the devices themselves. + * + * To handle these issues, libusb provides you with two separate items: + * - A function to free the list itself + * - A reference counting system for the devices inside + * + * New devices presented by the libusb_get_device_list() function all have a + * reference count of 1. You can increase and decrease reference count using + * libusb_ref_device() and libusb_unref_device(). A device is destroyed when + * its reference count reaches 0. + * + * With the above information in mind, the process of opening a device can + * be viewed as follows: + * -# Discover devices using libusb_get_device_list(). + * -# Choose the device that you want to operate, and call libusb_open(). + * -# Unref all devices in the discovered device list. + * -# Free the discovered device list. + * + * The order is important - you must not unreference the device before + * attempting to open it, because unreferencing it may destroy the device. + * + * For convenience, the libusb_free_device_list() function includes a + * parameter to optionally unreference all the devices in the list before + * freeing the list itself. This combines steps 3 and 4 above. + * + * As an implementation detail, libusb_open() actually adds a reference to + * the device in question. This is because the device remains available + * through the handle via libusb_get_device(). The reference is deleted during + * libusb_close(). + */ + +/** @defgroup libusb_misc Miscellaneous */ + +/* we traverse usbfs without knowing how many devices we are going to find. + * so we create this discovered_devs model which is similar to a linked-list + * which grows when required. it can be freed once discovery has completed, + * eliminating the need for a list node in the libusb_device structure + * itself. */ +#define DISCOVERED_DEVICES_SIZE_STEP 8 + +static struct discovered_devs *discovered_devs_alloc(void) +{ + struct discovered_devs *ret = + malloc(sizeof(*ret) + (sizeof(void *) * DISCOVERED_DEVICES_SIZE_STEP)); + + if (ret) { + ret->len = 0; + ret->capacity = DISCOVERED_DEVICES_SIZE_STEP; + } + return ret; +} + +static void discovered_devs_free(struct discovered_devs *discdevs) +{ + size_t i; + + for (i = 0; i < discdevs->len; i++) + libusb_unref_device(discdevs->devices[i]); + + free(discdevs); +} + +/* append a device to the discovered devices collection. may realloc itself, + * returning new discdevs. returns NULL on realloc failure. */ +struct discovered_devs *discovered_devs_append( + struct discovered_devs *discdevs, struct libusb_device *dev) +{ + size_t len = discdevs->len; + size_t capacity; + struct discovered_devs *new_discdevs; + + /* if there is space, just append the device */ + if (len < discdevs->capacity) { + discdevs->devices[len] = libusb_ref_device(dev); + discdevs->len++; + return discdevs; + } + + /* exceeded capacity, need to grow */ + usbi_dbg("need to increase capacity"); + capacity = discdevs->capacity + DISCOVERED_DEVICES_SIZE_STEP; + /* can't use usbi_reallocf here because in failure cases it would + * free the existing discdevs without unreferencing its devices. */ + new_discdevs = realloc(discdevs, + sizeof(*discdevs) + (sizeof(void *) * capacity)); + if (!new_discdevs) { + discovered_devs_free(discdevs); + return NULL; + } + + discdevs = new_discdevs; + discdevs->capacity = capacity; + discdevs->devices[len] = libusb_ref_device(dev); + discdevs->len++; + + return discdevs; +} + +/* Allocate a new device with a specific session ID.

You can also choose to use both interfaces in your + * application by considering each transfer on a case-by-case basis. + * + * Once you have read through the following discussion, you should consult the + * detailed API documentation pages for the details: + * - \ref libusb_syncio + * - \ref libusb_asyncio + * + * \section theory Transfers at a logical level + * + * At a logical level, USB transfers typically happen in two parts. For + * example, when reading data from a endpoint: + * -# A request for data is sent to the device + * -# Some time later, the incoming data is received by the host + * + * or when writing data to an endpoint: + * + * -# The data is sent to the device + * -# Some time later, the host receives acknowledgement from the device that + * the data has been transferred. + * + * There may be an indefinite delay between the two steps. Consider a + * fictional USB input device with a button that the user can press. In order + * to determine when the button is pressed, you would likely submit a request + * to read data on a bulk or interrupt endpoint and wait for data to arrive. + * Data will arrive when the button is pressed by the user, which is + * potentially hours later. + * + * libusb offers both a synchronous and an asynchronous interface to performing + * USB transfers. The main difference is that the synchronous interface + * combines both steps indicated above into a single function call, whereas + * the asynchronous interface separates them. + * + * \section sync The synchronous interface + * + * The synchronous I/O interface allows you to perform a USB transfer with + * a single function call. When the function call returns, the transfer has + * completed and you can parse the results. + * + * If you have used the libusb-0.1 before, this I/O style will seem familar to + * you. libusb-0.1 only offered a synchronous interface. + * + * In our input device example, to read button presses you might write code + * in the following style: +\code +unsigned char data[4]; +int actual_length; +int r = libusb_bulk_transfer(dev_handle, LIBUSB_ENDPOINT_IN, data, sizeof(data), &actual_length, 0); +if (r == 0 && actual_length == sizeof(data)) { + // results of the transaction can now be found in the data buffer + // parse them here and report button press +} else { + error(); +} +\endcode + * + * The main advantage of this model is simplicity: you did everything with + * a single simple function call. + * + * However, this interface has its limitations. Your application will sleep + * inside libusb_bulk_transfer() until the transaction has completed. If it + * takes the user 3 hours to press the button, your application will be + * sleeping for that long. Execution will be tied up inside the library - + * the entire thread will be useless for that duration. + * + * Another issue is that by tieing up the thread with that single transaction + * there is no possibility of performing I/O with multiple endpoints and/or + * multiple devices simultaneously, unless you resort to creating one thread + * per transaction. + * + * Additionally, there is no opportunity to cancel the transfer after the + * request has been submitted. + * + * For details on how to use the synchronous API, see the + * \ref libusb_syncio "synchronous I/O API documentation" pages. + * + * \section async The asynchronous interface + * + * Asynchronous I/O is the most significant new feature in libusb-1.0. + * Although it is a more complex interface, it solves all the issues detailed + * above. + * + * Instead of providing which functions that block until the I/O has complete, + * libusb's asynchronous interface presents non-blocking functions which + * begin a transfer and then return immediately. Your application passes a + * callback function pointer to this non-blocking function, which libusb will + * call with the results of the transaction when it has completed. + * + * Transfers which have been submitted through the non-blocking functions + * can be cancelled with a separate function call. + * + * The non-blocking nature of this interface allows you to be simultaneously + * performing I/O to multiple endpoints on multiple devices, without having + * to use threads. + * + * This added flexibility does come with some complications though: + * - In the interest of being a lightweight library, libusb does not create + * threads and can only operate when your application is calling into it. Your + * application must call into libusb from it's main loop when events are ready + * to be handled, or you must use some other scheme to allow libusb to + * undertake whatever work needs to be done. + * - libusb also needs to be called into at certain fixed points in time in + * order to accurately handle transfer timeouts. + * - Memory handling becomes more complex. You cannot use stack memory unless + * the function with that stack is guaranteed not to return until the transfer + * callback has finished executing. + * - You generally lose some linearity from your code flow because submitting + * the transfer request is done in a separate function from where the transfer + * results are handled. This becomes particularly obvious when you want to + * submit a second transfer based on the results of an earlier transfer. + * + * Internally, libusb's synchronous interface is expressed in terms of function + * calls to the asynchronous interface. + * + * For details on how to use the asynchronous API, see the + * \ref libusb_asyncio "asynchronous I/O API" documentation pages. + */ + + +/** + * \page libusb_packetoverflow Packets and overflows + * + * \section packets Packet abstraction + * + * The USB specifications describe how data is transmitted in packets, with + * constraints on packet size defined by endpoint descriptors. The host must + * not send data payloads larger than the endpoint's maximum packet size. + * + * libusb and the underlying OS abstract out the packet concept, allowing you + * to request transfers of any size. Internally, the request will be divided + * up into correctly-sized packets. You do not have to be concerned with + * packet sizes, but there is one exception when considering overflows. + * + * \section overflow Bulk/interrupt transfer overflows + * + * When requesting data on a bulk endpoint, libusb requires you to supply a + * buffer and the maximum number of bytes of data that libusb can put in that + * buffer. However, the size of the buffer is not communicated to the device - + * the device is just asked to send any amount of data. + * + * There is no problem if the device sends an amount of data that is less than + * or equal to the buffer size. libusb reports this condition to you through + * the \ref libusb_transfer::actual_length "libusb_transfer.actual_length" + * field. + * + * Problems may occur if the device attempts to send more data than can fit in + * the buffer. libusb reports LIBUSB_TRANSFER_OVERFLOW for this condition but + * other behaviour is largely undefined: actual_length may or may not be + * accurate, the chunk of data that can fit in the buffer (before overflow) + * may or may not have been transferred. + * + * Overflows are nasty, but can be avoided. Even though you were told to + * ignore packets above, think about the lower level details: each transfer is + * split into packets (typically small, with a maximum size of 512 bytes). + * Overflows can only happen if the final packet in an incoming data transfer + * is smaller than the actual packet that the device wants to transfer. + * Therefore, you will never see an overflow if your transfer buffer size is a + * multiple of the endpoint's packet size: the final packet will either + * fill up completely or will be only partially filled. + */ + +/** + * @defgroup libusb_asyncio Asynchronous device I/O + * + * This page details libusb's asynchronous (non-blocking) API for USB device + * I/O. This interface is very powerful but is also quite complex - you will + * need to read this page carefully to understand the necessary considerations + * and issues surrounding use of this interface. Simplistic applications + * may wish to consider the \ref libusb_syncio "synchronous I/O API" instead. + * + * The asynchronous interface is built around the idea of separating transfer + * submission and handling of transfer completion (the synchronous model + * combines both of these into one). There may be a long delay between + * submission and completion, however the asynchronous submission function + * is non-blocking so will return control to your application during that + * potentially long delay. + * + * \section asyncabstraction Transfer abstraction + * + * For the asynchronous I/O, libusb implements the concept of a generic + * transfer entity for all types of I/O (control, bulk, interrupt, + * isochronous). The generic transfer object must be treated slightly + * differently depending on which type of I/O you are performing with it. + * + * This is represented by the public libusb_transfer structure type. + * + * \section asynctrf Asynchronous transfers + * + * We can view asynchronous I/O as a 5 step process: + * -# <b>Allocation</b>: allocate a libusb_transfer + * -# <b>Filling</b>: populate the libusb_transfer instance with information + * about the transfer you wish to perform + * -# <b>Submission</b>: ask libusb to submit the transfer + * -# <b>Completion handling</b>: examine transfer results in the + * libusb_transfer structure + * -# <b>Deallocation</b>: clean up resources + * + * + * \subsection asyncalloc Allocation + * + * This step involves allocating memory for a USB transfer. This is the + * generic transfer object mentioned above. At this stage, the transfer + * is "blank" with no details about what type of I/O it will be used for. + * + * Allocation is done with the libusb_alloc_transfer() function. You must use + * this function rather than allocating your own transfers. + * + * \subsection asyncfill Filling + * + * This step is where you take a previously allocated transfer and fill it + * with information to determine the message type and direction, data buffer, + * callback function, etc. + * + * You can either fill the required fields yourself or you can use the + * helper functions: libusb_fill_control_transfer(), libusb_fill_bulk_transfer() + * and libusb_fill_interrupt_transfer(). + * + * \subsection asyncsubmit Submission + * + * When you have allocated a transfer and filled it, you can submit it using + * libusb_submit_transfer(). This function returns immediately but can be + * regarded as firing off the I/O request in the background. + * + * \subsection asynccomplete Completion handling + * + * After a transfer has been submitted, one of four things can happen to it: + * + * - The transfer completes (i.e. some data was transferred) + * - The transfer has a timeout and the timeout expires before all data is + * transferred + * - The transfer fails due to an error + * - The transfer is cancelled + * + * Each of these will cause the user-specified transfer callback function to + * be invoked. It is up to the callback function to determine which of the + * above actually happened and to act accordingly. + * + * The user-specified callback is passed a pointer to the libusb_transfer + * structure which was used to setup and submit the transfer. At completion + * time, libusb has populated this structure with results of the transfer: + * success or failure reason, number of bytes of data transferred, etc. See + * the libusb_transfer structure documentation for more information. + * + * <b>Important Note</b>: The user-specified callback is called from an event + * handling context. It is therefore important that no calls are made into + * libusb that will attempt to perform any event handling. Examples of such + * functions are any listed in the \ref libusb_syncio "synchronous API" and any of + * the blocking functions that retrieve \ref libusb_desc "USB descriptors". + * + * \subsection Deallocation + * + * When a transfer has completed (i.e. the callback function has been invoked), + * you are advised to free the transfer (unless you wish to resubmit it, see + * below). Transfers are deallocated with libusb_free_transfer(). + * + * It is undefined behaviour to free a transfer which has not completed. + * + * \section asyncresubmit Resubmission + * + * You may be wondering why allocation, filling, and submission are all + * separated above where they could reasonably be combined into a single + * operation. + * + * The reason for separation is to allow you to resubmit transfers without + * having to allocate new ones every time. This is especially useful for + * common situations dealing with interrupt endpoints - you allocate one + * transfer, fill and submit it, and when it returns with results you just + * resubmit it for the next interrupt. + * + * \section asynccancel Cancellation + * + * Another advantage of using the asynchronous interface is that you have + * the ability to cancel transfers which have not yet completed. This is + * done by calling the libusb_cancel_transfer() function. + * + * libusb_cancel_transfer() is asynchronous/non-blocking in itself. When the + * cancellation actually completes, the transfer's callback function will + * be invoked, and the callback function should check the transfer status to + * determine that it was cancelled. + * + * Freeing the transfer after it has been cancelled but before cancellation + * has completed will result in undefined behaviour. + * + * When a transfer is cancelled, some of the data may have been transferred. + * libusb will communicate this to you in the transfer callback. Do not assume + * that no data was transferred. + * + * \section bulk_overflows Overflows on device-to-host bulk/interrupt endpoints + * + * If your device does not have predictable transfer sizes (or it misbehaves), + * your application may submit a request for data on an IN endpoint which is + * smaller than the data that the device wishes to send. In some circumstances + * this will cause an overflow, which is a nasty condition to deal with. See + * the \ref libusb_packetoverflow page for discussion. + * + * \section asyncctrl Considerations for control transfers + * + * The <tt>libusb_transfer</tt> structure is generic and hence does not + * include specific fields for the control-specific setup packet structure. + * + * In order to perform a control transfer, you must place the 8-byte setup + * packet at the start of the data buffer. To simplify this, you could + * cast the buffer pointer to type struct libusb_control_setup, or you can + * use the helper function libusb_fill_control_setup(). + * + * The wLength field placed in the setup packet must be the length you would + * expect to be sent in the setup packet: the length of the payload that + * follows (or the expected maximum number of bytes to receive). However, + * the length field of the libusb_transfer object must be the length of + * the data buffer - i.e. it should be wLength <em>plus</em> the size of + * the setup packet (LIBUSB_CONTROL_SETUP_SIZE). + * + * If you use the helper functions, this is simplified for you: + * -# Allocate a buffer of size LIBUSB_CONTROL_SETUP_SIZE plus the size of the + * data you are sending/requesting. + * -# Call libusb_fill_control_setup() on the data buffer, using the transfer + * request size as the wLength value (i.e. do not include the extra space you + * allocated for the control setup). + * -# If this is a host-to-device transfer, place the data to be transferred + * in the data buffer, starting at offset LIBUSB_CONTROL_SETUP_SIZE. + * -# Call libusb_fill_control_transfer() to associate the data buffer with + * the transfer (and to set the remaining details such as callback and timeout). + * - Note that there is no parameter to set the length field of the transfer. + * The length is automatically inferred from the wLength field of the setup + * packet. + * -# Submit the transfer. + * + * The multi-byte control setup fields (wValue, wIndex and wLength) must + * be given in little-endian byte order (the endianness of the USB bus). + * Endianness conversion is transparently handled by + * libusb_fill_control_setup() which is documented to accept host-endian + * values. + * + * Further considerations are needed when handling transfer completion in + * your callback function: + * - As you might expect, the setup packet will still be sitting at the start + * of the data buffer. + * - If this was a device-to-host transfer, the received data will be sitting + * at offset LIBUSB_CONTROL_SETUP_SIZE into the buffer. + * - The actual_length field of the transfer structure is relative to the + * wLength of the setup packet, rather than the size of the data buffer. So, + * if your wLength was 4, your transfer's <tt>length</tt> was 12, then you + * should expect an <tt>actual_length</tt> of 4 to indicate that the data was + * transferred in entirity. + * + * To simplify parsing of setup packets and obtaining the data from the + * correct offset, you may wish to use the libusb_control_transfer_get_data() + * and libusb_control_transfer_get_setup() functions within your transfer + * callback. + * + * Even though control endpoints do not halt, a completed control transfer + * may have a LIBUSB_TRANSFER_STALL status code. This indicates the control + * request was not supported. + * + * \section asyncintr Considerations for interrupt transfers + * + * All interrupt transfers are performed using the polling interval presented + * by the bInterval value of the endpoint descriptor. + * + * \section asynciso Considerations for isochronous transfers + * + * Isochronous transfers are more complicated than transfers to + * non-isochronous endpoints. + * + * To perform I/O to an isochronous endpoint, allocate the transfer by calling + * libusb_alloc_transfer() with an appropriate number of isochronous packets. + * + * During filling, set \ref libusb_transfer::type "type" to + * \ref libusb_transfer_type::LIBUSB_TRANSFER_TYPE_ISOCHRONOUS + * "LIBUSB_TRANSFER_TYPE_ISOCHRONOUS", and set + * \ref libusb_transfer::num_iso_packets "num_iso_packets" to a value less than + * or equal to the number of packets you requested during allocation. + * libusb_alloc_transfer() does not set either of these fields for you, given + * that you might not even use the transfer on an isochronous endpoint. + * + * Next, populate the length field for the first num_iso_packets entries in + * the \ref libusb_transfer::iso_packet_desc "iso_packet_desc" array. Section + * 5.6.3 of the USB2 specifications describe how the maximum isochronous + * packet length is determined by the wMaxPacketSize field in the endpoint + * descriptor. + * Two functions can help you here: + * + * - libusb_get_max_iso_packet_size() is an easy way to determine the max + * packet size for an isochronous endpoint. Note that the maximum packet + * size is actually the maximum number of bytes that can be transmitted in + * a single microframe, therefore this function multiplies the maximum number + * of bytes per transaction by the number of transaction opportunities per + * microframe. + * - libusb_set_iso_packet_lengths() assigns the same length to all packets + * within a transfer, which is usually what you want. + * + * For outgoing transfers, you'll obviously fill the buffer and populate the + * packet descriptors in hope that all the data gets transferred. For incoming + * transfers, you must ensure the buffer has sufficient capacity for + * the situation where all packets transfer the full amount of requested data. + * + * Completion handling requires some extra consideration. The + * \ref libusb_transfer::actual_length "actual_length" field of the transfer + * is meaningless and should not be examined; instead you must refer to the + * \ref libusb_iso_packet_descriptor::actual_length "actual_length" field of + * each individual packet. + * + * The \ref libusb_transfer::status "status" field of the transfer is also a + * little misleading: + * - If the packets were submitted and the isochronous data microframes + * completed normally, status will have value + * \ref libusb_transfer_status::LIBUSB_TRANSFER_COMPLETED + * "LIBUSB_TRANSFER_COMPLETED". Note that bus errors and software-incurred + * delays are not counted as transfer errors; the transfer.status field may + * indicate COMPLETED even if some or all of the packets failed. Refer to + * the \ref libusb_iso_packet_descriptor::status "status" field of each + * individual packet to determine packet failures. + * - The status field will have value + * \ref libusb_transfer_status::LIBUSB_TRANSFER_ERROR + * "LIBUSB_TRANSFER_ERROR" only when serious errors were encountered. + * - Other transfer status codes occur with normal behaviour. + * + * The data for each packet will be found at an offset into the buffer that + * can be calculated as if each prior packet completed in full. The + * libusb_get_iso_packet_buffer() and libusb_get_iso_packet_buffer_simple() + * functions may help you here. + * + * <b>Note</b>: Some operating systems (e.g. Linux) may impose limits on the + * length of individual isochronous packets and/or the total length of the + * isochronous transfer. Such limits can be difficult for libusb to detect, + * so the library will simply try and submit the transfer as set up by you. + * If the transfer fails to submit because it is too large, + * libusb_submit_transfer() will return + * \ref libusb_error::LIBUSB_ERROR_INVALID_PARAM "LIBUSB_ERROR_INVALID_PARAM". + * + * \section asyncmem Memory caveats + * + * In most circumstances, it is not safe to use stack memory for transfer + * buffers. This is because the function that fired off the asynchronous + * transfer may return before libusb has finished using the buffer, and when + * the function returns it's stack gets destroyed. This is true for both + * host-to-device and device-to-host transfers. + * + * The only case in which it is safe to use stack memory is where you can + * guarantee that the function owning the stack space for the buffer does not + * return until after the transfer's callback function has completed. In every + * other case, you need to use heap memory instead. + * + * \section asyncflags Fine control + * + * Through using this asynchronous interface, you may find yourself repeating + * a few simple operations many times. You can apply a bitwise OR of certain + * flags to a transfer to simplify certain things: + * - \ref libusb_transfer_flags::LIBUSB_TRANSFER_SHORT_NOT_OK + * "LIBUSB_TRANSFER_SHORT_NOT_OK" results in transfers which transferred + * less than the requested amount of data being marked with status + * \ref libusb_transfer_status::LIBUSB_TRANSFER_ERROR "LIBUSB_TRANSFER_ERROR" + * (they would normally be regarded as COMPLETED) + * - \ref libusb_transfer_flags::LIBUSB_TRANSFER_FREE_BUFFER + * "LIBUSB_TRANSFER_FREE_BUFFER" allows you to ask libusb to free the transfer + * buffer when freeing the transfer. + * - \ref libusb_transfer_flags::LIBUSB_TRANSFER_FREE_TRANSFER + * "LIBUSB_TRANSFER_FREE_TRANSFER" causes libusb to automatically free the + * transfer after the transfer callback returns. + * + * \section asyncevent Event handling + * + * An asynchronous model requires that libusb perform work at various + * points in time - namely processing the results of previously-submitted + * transfers and invoking the user-supplied callback function. + * + * This gives rise to the libusb_handle_events() function which your + * application must call into when libusb has work do to. This gives libusb + * the opportunity to reap pending transfers, invoke callbacks, etc. + * + * There are 2 different approaches to dealing with libusb_handle_events: + * + * -# Repeatedly call libusb_handle_events() in blocking mode from a dedicated + * thread. + * -# Integrate libusb with your application's main event loop. libusb + * exposes a set of file descriptors which allow you to do this. + * + * The first approach has the big advantage that it will also work on Windows + * were libusb' poll API for select / poll integration is not available. So + * if you want to support Windows and use the async API, you must use this + * approach, see the \ref eventthread "Using an event handling thread" section + * below for details. + * + * If you prefer a single threaded approach with a single central event loop, + * see the \ref libusb_poll "polling and timing" section for how to integrate libusb + * into your application's main event loop. + * + * \section eventthread Using an event handling thread + * + * Lets begin with stating the obvious: If you're going to use a separate + * thread for libusb event handling, your callback functions MUST be + * threadsafe. + * + * Other then that doing event handling from a separate thread, is mostly + * simple. You can use an event thread function as follows: +\code +void *event_thread_func(void *ctx) +{ + while (event_thread_run) + libusb_handle_events(ctx); + + return NULL; +} +\endcode + * + * There is one caveat though, stopping this thread requires setting the + * event_thread_run variable to 0, and after that libusb_handle_events() needs + * to return control to event_thread_func. But unless some event happens, + * libusb_handle_events() will not return. + * + * There are 2 different ways of dealing with this, depending on if your + * application uses libusb' \ref libusb_hotplug "hotplug" support or not. + * + * Applications which do not use hotplug support, should not start the event + * thread until after their first call to libusb_open(), and should stop the + * thread when closing the last open device as follows: +\code +void my_close_handle(libusb_device_handle *dev_handle) +{ + if (open_devs == 1) + event_thread_run = 0; + + libusb_close(dev_handle); // This wakes up libusb_handle_events() + + if (open_devs == 1) + pthread_join(event_thread); + + open_devs--; +} +\endcode + * + * Applications using hotplug support should start the thread at program init, + * after having successfully called libusb_hotplug_register_callback(), and + * should stop the thread at program exit as follows: +\code +void my_libusb_exit(void) +{ + event_thread_run = 0; + libusb_hotplug_deregister_callback(ctx, hotplug_cb_handle); // This wakes up libusb_handle_events() + pthread_join(event_thread); + libusb_exit(ctx); +} +\endcode + */ + +/** + * @defgroup libusb_poll Polling and timing + * + * This page documents libusb's functions for polling events and timing. + * These functions are only necessary for users of the + * \ref libusb_asyncio "asynchronous API". If you are only using the simpler + * \ref libusb_syncio "synchronous API" then you do not need to ever call these + * functions. + * + * The justification for the functionality described here has already been + * discussed in the \ref asyncevent "event handling" section of the + * asynchronous API documentation. In summary, libusb does not create internal + * threads for event processing and hence relies on your application calling + * into libusb at certain points in time so that pending events can be handled. + * + * Your main loop is probably already calling poll() or select() or a + * variant on a set of file descriptors for other event sources (e.g. keyboard + * button presses, mouse movements, network sockets, etc). You then add + * libusb's file descriptors to your poll()/select() calls, and when activity + * is detected on such descriptors you know it is time to call + * libusb_handle_events(). + * + * There is one final event handling complication. libusb supports + * asynchronous transfers which time out after a specified time period. + * + * On some platforms a timerfd is used, so the timeout handling is just another + * fd, on other platforms this requires that libusb is called into at or after + * the timeout to handle it. So, in addition to considering libusb's file + * descriptors in your main event loop, you must also consider that libusb + * sometimes needs to be called into at fixed points in time even when there + * is no file descriptor activity, see \ref polltime details. + * + * In order to know precisely when libusb needs to be called into, libusb + * offers you a set of pollable file descriptors and information about when + * the next timeout expires. + * + * If you are using the asynchronous I/O API, you must take one of the two + * following options, otherwise your I/O will not complete. + * + * \section pollsimple The simple option + * + * If your application revolves solely around libusb and does not need to + * handle other event sources, you can have a program structure as follows: +\code +// initialize libusb +// find and open device +// maybe fire off some initial async I/O + +while (user_has_not_requested_exit) + libusb_handle_events(ctx); + +// clean up and exit +\endcode + * + * With such a simple main loop, you do not have to worry about managing + * sets of file descriptors or handling timeouts. libusb_handle_events() will + * handle those details internally. + * + * \section libusb_pollmain The more advanced option + * + * \note This functionality is currently only available on Unix-like platforms. + * On Windows, libusb_get_pollfds() simply returns NULL. Applications which + * want to support Windows are advised to use an \ref eventthread + * "event handling thread" instead. + * + * In more advanced applications, you will already have a main loop which + * is monitoring other event sources: network sockets, X11 events, mouse + * movements, etc. Through exposing a set of file descriptors, libusb is + * designed to cleanly integrate into such main loops. + * + * In addition to polling file descriptors for the other event sources, you + * take a set of file descriptors from libusb and monitor those too. When you + * detect activity on libusb's file descriptors, you call + * libusb_handle_events_timeout() in non-blocking mode. + * + * What's more, libusb may also need to handle events at specific moments in + * time. No file descriptor activity is generated at these times, so your + * own application needs to be continually aware of when the next one of these + * moments occurs (through calling libusb_get_next_timeout()), and then it + * needs to call libusb_handle_events_timeout() in non-blocking mode when + * these moments occur. This means that you need to adjust your + * poll()/select() timeout accordingly. + * + * libusb provides you with a set of file descriptors to poll and expects you + * to poll all of them, treating them as a single entity. The meaning of each + * file descriptor in the set is an internal implementation detail, + * platform-dependent and may vary from release to release. Don't try and + * interpret the meaning of the file descriptors, just do as libusb indicates, + * polling all of them at once. + * + * In pseudo-code, you want something that looks like: +\code +// initialise libusb + +libusb_get_pollfds(ctx) +while (user has not requested application exit) { + libusb_get_next_timeout(ctx); + poll(on libusb file descriptors plus any other event sources of interest, + using a timeout no larger than the value libusb just suggested) + if (poll() indicated activity on libusb file descriptors) + libusb_handle_events_timeout(ctx, &zero_tv); + if (time has elapsed to or beyond the libusb timeout) + libusb_handle_events_timeout(ctx, &zero_tv); + // handle events from other sources here +} + +// clean up and exit +\endcode + * + * \subsection polltime Notes on time-based events + * + * The above complication with having to track time and call into libusb at + * specific moments is a bit of a headache. For maximum compatibility, you do + * need to write your main loop as above, but you may decide that you can + * restrict the supported platforms of your application and get away with + * a more simplistic scheme. + * + * These time-based event complications are \b not required on the following + * platforms: + * - Darwin + * - Linux, provided that the following version requirements are satisfied: + * - Linux v2.6.27 or newer, compiled with timerfd support + * - glibc v2.9 or newer + * - libusb v1.0.5 or newer + * + * Under these configurations, libusb_get_next_timeout() will \em always return + * 0, so your main loop can be simplified to: +\code +// initialise libusb + +libusb_get_pollfds(ctx) +while (user has not requested application exit) { + poll(on libusb file descriptors plus any other event sources of interest, + using any timeout that you like) + if (poll() indicated activity on libusb file descriptors) + libusb_handle_events_timeout(ctx, &zero_tv); + // handle events from other sources here +} + +// clean up and exit +\endcode + * + * Do remember that if you simplify your main loop to the above, you will + * lose compatibility with some platforms (including legacy Linux platforms, + * and <em>any future platforms supported by libusb which may have time-based + * event requirements</em>). The resultant problems will likely appear as + * strange bugs in your application. + * + * You can use the libusb_pollfds_handle_timeouts() function to do a runtime + * check to see if it is safe to ignore the time-based event complications. + * If your application has taken the shortcut of ignoring libusb's next timeout + * in your main loop, then you are advised to check the return value of + * libusb_pollfds_handle_timeouts() during application startup, and to abort + * if the platform does suffer from these timing complications. + * + * \subsection fdsetchange Changes in the file descriptor set + * + * The set of file descriptors that libusb uses as event sources may change + * during the life of your application. Rather than having to repeatedly + * call libusb_get_pollfds(), you can set up notification functions for when + * the file descriptor set changes using libusb_set_pollfd_notifiers(). + * + * \subsection mtissues Multi-threaded considerations + * + * Unfortunately, the situation is complicated further when multiple threads + * come into play. If two threads are monitoring the same file descriptors, + * the fact that only one thread will be woken up when an event occurs causes + * some headaches. + * + * The events lock, event waiters lock, and libusb_handle_events_locked() + * entities are added to solve these problems. You do not need to be concerned + * with these entities otherwise. + * + * See the extra documentation: \ref libusb_mtasync + */ + +/** \page libusb_mtasync Multi-threaded applications and asynchronous I/O + * + * libusb is a thread-safe library, but extra considerations must be applied + * to applications which interact with libusb from multiple threads. + * + * The underlying issue that must be addressed is that all libusb I/O + * revolves around monitoring file descriptors through the poll()/select() + * system calls. This is directly exposed at the + * \ref libusb_asyncio "asynchronous interface" but it is important to note that the + * \ref libusb_syncio "synchronous interface" is implemented on top of the + * asynchonrous interface, therefore the same considerations apply. + * + * The issue is that if two or more threads are concurrently calling poll() + * or select() on libusb's file descriptors then only one of those threads + * will be woken up when an event arrives. The others will be completely + * oblivious that anything has happened. + * + * Consider the following pseudo-code, which submits an asynchronous transfer + * then waits for its completion. This style is one way you could implement a + * synchronous interface on top of the asynchronous interface (and libusb + * does something similar, albeit more advanced due to the complications + * explained on this page). + * +\code +void cb(struct libusb_transfer *transfer) +{ + int *completed = transfer->user_data; + *completed = 1; +} + +void myfunc() { + struct libusb_transfer *transfer; + unsigned char buffer[LIBUSB_CONTROL_SETUP_SIZE] __attribute__ ((aligned (2))); + int completed = 0; + + transfer = libusb_alloc_transfer(0); + libusb_fill_control_setup(buffer, + LIBUSB_REQUEST_TYPE_VENDOR | LIBUSB_ENDPOINT_OUT, 0x04, 0x01, 0, 0); + libusb_fill_control_transfer(transfer, dev, buffer, cb, &completed, 1000); + libusb_submit_transfer(transfer); + + while (!completed) { + poll(libusb file descriptors, 120*1000); + if (poll indicates activity) + libusb_handle_events_timeout(ctx, &zero_tv); + } + printf("completed!"); + // other code here +} +\endcode + * + * Here we are <em>serializing</em> completion of an asynchronous event + * against a condition - the condition being completion of a specific transfer. + * The poll() loop has a long timeout to minimize CPU usage during situations + * when nothing is happening (it could reasonably be unlimited). + * + * If this is the only thread that is polling libusb's file descriptors, there + * is no problem: there is no danger that another thread will swallow up the + * event that we are interested in. On the other hand, if there is another + * thread polling the same descriptors, there is a chance that it will receive + * the event that we were interested in. In this situation, <tt>myfunc()</tt> + * will only realise that the transfer has completed on the next iteration of + * the loop, <em>up to 120 seconds later.</em> Clearly a two-minute delay is + * undesirable, and don't even think about using short timeouts to circumvent + * this issue! + * + * The solution here is to ensure that no two threads are ever polling the + * file descriptors at the same time. A naive implementation of this would + * impact the capabilities of the library, so libusb offers the scheme + * documented below to ensure no loss of functionality. + * + * Before we go any further, it is worth mentioning that all libusb-wrapped + * event handling procedures fully adhere to the scheme documented below. + * This includes libusb_handle_events() and its variants, and all the + * synchronous I/O functions - libusb hides this headache from you. + * + * \section Using libusb_handle_events() from multiple threads + * + * Even when only using libusb_handle_events() and synchronous I/O functions, + * you can still have a race condition. You might be tempted to solve the + * above with libusb_handle_events() like so: + * +\code + libusb_submit_transfer(transfer); + + while (!completed) { + libusb_handle_events(ctx); + } + printf("completed!"); +\endcode + * + * This however has a race between the checking of completed and + * libusb_handle_events() acquiring the events lock, so another thread + * could have completed the transfer, resulting in this thread hanging + * until either a timeout or another event occurs. See also commit + * 6696512aade99bb15d6792af90ae329af270eba6 which fixes this in the + * synchronous API implementation of libusb. + * + * Fixing this race requires checking the variable completed only after + * taking the event lock, which defeats the concept of just calling + * libusb_handle_events() without worrying about locking. This is why + * libusb-1.0.9 introduces the new libusb_handle_events_timeout_completed() + * and libusb_handle_events_completed() functions, which handles doing the + * completion check for you after they have acquired the lock: + * +\code + libusb_submit_transfer(transfer); + + while (!completed) { + libusb_handle_events_completed(ctx, &completed); + } + printf("completed!"); +\endcode + * + * This nicely fixes the race in our example. Note that if all you want to + * do is submit a single transfer and wait for its completion, then using + * one of the synchronous I/O functions is much easier. + * + * \section eventlock The events lock + * + * The problem is when we consider the fact that libusb exposes file + * descriptors to allow for you to integrate asynchronous USB I/O into + * existing main loops, effectively allowing you to do some work behind + * libusb's back. If you do take libusb's file descriptors and pass them to + * poll()/select() yourself, you need to be aware of the associated issues. + * + * The first concept to be introduced is the events lock. The events lock + * is used to serialize threads that want to handle events, such that only + * one thread is handling events at any one time. + * + * You must take the events lock before polling libusb file descriptors, + * using libusb_lock_events(). You must release the lock as soon as you have + * aborted your poll()/select() loop, using libusb_unlock_events(). + * + * \section threadwait Letting other threads do the work for you + * + * Although the events lock is a critical part of the solution, it is not + * enough on it's own. You might wonder if the following is sufficient... +\code + libusb_lock_events(ctx); + while (!completed) { + poll(libusb file descriptors, 120*1000); + if (poll indicates activity) + libusb_handle_events_timeout(ctx, &zero_tv); + } + libusb_unlock_events(ctx); +\endcode + * ...and the answer is that it is not. This is because the transfer in the + * code shown above may take a long time (say 30 seconds) to complete, and + * the lock is not released until the transfer is completed. + * + * Another thread with similar code that wants to do event handling may be + * working with a transfer that completes after a few milliseconds. Despite + * having such a quick completion time, the other thread cannot check that + * status of its transfer until the code above has finished (30 seconds later) + * due to contention on the lock. + * + * To solve this, libusb offers you a mechanism to determine when another + * thread is handling events. It also offers a mechanism to block your thread + * until the event handling thread has completed an event (and this mechanism + * does not involve polling of file descriptors). + * + * After determining that another thread is currently handling events, you + * obtain the <em>event waiters</em> lock using libusb_lock_event_waiters(). + * You then re-check that some other thread is still handling events, and if + * so, you call libusb_wait_for_event(). + * + * libusb_wait_for_event() puts your application to sleep until an event + * occurs, or until a thread releases the events lock. When either of these + * things happen, your thread is woken up, and should re-check the condition + * it was waiting on. It should also re-check that another thread is handling + * events, and if not, it should start handling events itself. + * + * This looks like the following, as pseudo-code: +\code +retry: +if (libusb_try_lock_events(ctx) == 0) { + // we obtained the event lock: do our own event handling + while (!completed) { + if (!libusb_event_handling_ok(ctx)) { + libusb_unlock_events(ctx); + goto retry; + } + poll(libusb file descriptors, 120*1000); + if (poll indicates activity) + libusb_handle_events_locked(ctx, 0); + } + libusb_unlock_events(ctx); +} else { + // another thread is doing event handling. wait for it to signal us that + // an event has completed + libusb_lock_event_waiters(ctx); + + while (!completed) { + // now that we have the event waiters lock, double check that another + // thread is still handling events for us. (it may have ceased handling + // events in the time it took us to reach this point) + if (!libusb_event_handler_active(ctx)) { + // whoever was handling events is no longer doing so, try again + libusb_unlock_event_waiters(ctx); + goto retry; + } + + libusb_wait_for_event(ctx, NULL); + } + libusb_unlock_event_waiters(ctx); +} +printf("completed!\n"); +\endcode + * + * A naive look at the above code may suggest that this can only support + * one event waiter (hence a total of 2 competing threads, the other doing + * event handling), because the event waiter seems to have taken the event + * waiters lock while waiting for an event. However, the system does support + * multiple event waiters, because libusb_wait_for_event() actually drops + * the lock while waiting, and reaquires it before continuing. + * + * We have now implemented code which can dynamically handle situations where + * nobody is handling events (so we should do it ourselves), and it can also + * handle situations where another thread is doing event handling (so we can + * piggyback onto them). It is also equipped to handle a combination of + * the two, for example, another thread is doing event handling, but for + * whatever reason it stops doing so before our condition is met, so we take + * over the event handling. + * + * Four functions were introduced in the above pseudo-code. Their importance + * should be apparent from the code shown above. + * -# libusb_try_lock_events() is a non-blocking function which attempts + * to acquire the events lock but returns a failure code if it is contended. + * -# libusb_event_handling_ok() checks that libusb is still happy for your + * thread to be performing event handling. Sometimes, libusb needs to + * interrupt the event handler, and this is how you can check if you have + * been interrupted. If this function returns 0, the correct behaviour is + * for you to give up the event handling lock, and then to repeat the cycle. + * The following libusb_try_lock_events() will fail, so you will become an + * events waiter. For more information on this, read \ref fullstory below. + * -# libusb_handle_events_locked() is a variant of + * libusb_handle_events_timeout() that you can call while holding the + * events lock. libusb_handle_events_timeout() itself implements similar + * logic to the above, so be sure not to call it when you are + * "working behind libusb's back", as is the case here. + * -# libusb_event_handler_active() determines if someone is currently + * holding the events lock + * + * You might be wondering why there is no function to wake up all threads + * blocked on libusb_wait_for_event(). This is because libusb can do this + * internally: it will wake up all such threads when someone calls + * libusb_unlock_events() or when a transfer completes (at the point after its + * callback has returned). + * + * \subsection fullstory The full story + * + * The above explanation should be enough to get you going, but if you're + * really thinking through the issues then you may be left with some more + * questions regarding libusb's internals. If you're curious, read on, and if + * not, skip to the next section to avoid confusing yourself! + * + * The immediate question that may spring to mind is: what if one thread + * modifies the set of file descriptors that need to be polled while another + * thread is doing event handling? + * + * There are 2 situations in which this may happen. + * -# libusb_open() will add another file descriptor to the poll set, + * therefore it is desirable to interrupt the event handler so that it + * restarts, picking up the new descriptor. + * -# libusb_close() will remove a file descriptor from the poll set. There + * are all kinds of race conditions that could arise here, so it is + * important that nobody is doing event handling at this time. + * + * libusb handles these issues internally, so application developers do not + * have to stop their event handlers while opening/closing devices. Here's how + * it works, focusing on the libusb_close() situation first: + * + * -# During initialization, libusb opens an internal pipe, and it adds the read + * end of this pipe to the set of file descriptors to be polled. + * -# During libusb_close(), libusb writes some dummy data on this event pipe. + * This immediately interrupts the event handler. libusb also records + * internally that it is trying to interrupt event handlers for this + * high-priority event. + * -# At this point, some of the functions described above start behaving + * differently: + * - libusb_event_handling_ok() starts returning 1, indicating that it is NOT + * OK for event handling to continue. + * - libusb_try_lock_events() starts returning 1, indicating that another + * thread holds the event handling lock, even if the lock is uncontended. + * - libusb_event_handler_active() starts returning 1, indicating that + * another thread is doing event handling, even if that is not true. + * -# The above changes in behaviour result in the event handler stopping and + * giving up the events lock very quickly, giving the high-priority + * libusb_close() operation a "free ride" to acquire the events lock. All + * threads that are competing to do event handling become event waiters. + * -# With the events lock held inside libusb_close(), libusb can safely remove + * a file descriptor from the poll set, in the safety of knowledge that + * nobody is polling those descriptors or trying to access the poll set. + * -# After obtaining the events lock, the close operation completes very + * quickly (usually a matter of milliseconds) and then immediately releases + * the events lock. + * -# At the same time, the behaviour of libusb_event_handling_ok() and friends + * reverts to the original, documented behaviour. + * -# The release of the events lock causes the threads that are waiting for + * events to be woken up and to start competing to become event handlers + * again. One of them will succeed; it will then re-obtain the list of poll + * descriptors, and USB I/O will then continue as normal. + * + * libusb_open() is similar, and is actually a more simplistic case. Upon a + * call to libusb_open(): + * + * -# The device is opened and a file descriptor is added to the poll set. + * -# libusb sends some dummy data on the event pipe, and records that it + * is trying to modify the poll descriptor set. + * -# The event handler is interrupted, and the same behaviour change as for + * libusb_close() takes effect, causing all event handling threads to become + * event waiters. + * -# The libusb_open() implementation takes its free ride to the events lock. + * -# Happy that it has successfully paused the events handler, libusb_open() + * releases the events lock. + * -# The event waiter threads are all woken up and compete to become event + * handlers again. The one that succeeds will obtain the list of poll + * descriptors again, which will include the addition of the new device. + * + * \subsection concl Closing remarks + * + * The above may seem a little complicated, but hopefully I have made it clear + * why such complications are necessary. Also, do not forget that this only + * applies to applications that take libusb's file descriptors and integrate + * them into their own polling loops. + * + * You may decide that it is OK for your multi-threaded application to ignore + * some of the rules and locks detailed above, because you don't think that + * two threads can ever be polling the descriptors at the same time. If that + * is the case, then that's good news for you because you don't have to worry. + * But be careful here; remember that the synchronous I/O functions do event + * handling internally. If you have one thread doing event handling in a loop + * (without implementing the rules and locking semantics documented above) + * and another trying to send a synchronous USB transfer, you will end up with + * two threads monitoring the same descriptors, and the above-described + * undesirable behaviour occurring. The solution is for your polling thread to + * play by the rules; the synchronous I/O functions do so, and this will result + * in them getting along in perfect harmony. + * + * If you do have a dedicated thread doing event handling, it is perfectly + * legal for it to take the event handling lock for long periods of time. Any + * synchronous I/O functions you call from other threads will transparently + * fall back to the "event waiters" mechanism detailed above. The only + * consideration that your event handling thread must apply is the one related + * to libusb_event_handling_ok(): you must call this before every poll(), and + * give up the events lock if instructed. + */ + +int usbi_io_init(struct libusb_context *ctx) +{ + int r; + + usbi_mutex_init(&ctx->flying_transfers_lock); + usbi_mutex_init(&ctx->events_lock); + usbi_mutex_init(&ctx->event_waiters_lock); + usbi_cond_init(&ctx->event_waiters_cond); + usbi_mutex_init(&ctx->event_data_lock); + usbi_tls_key_create(&ctx->event_handling_key); + list_init(&ctx->flying_transfers); + list_init(&ctx->ipollfds); + list_init(&ctx->hotplug_msgs); + list_init(&ctx->completed_transfers); + + /* FIXME should use an eventfd on kernels that support it */ + r = usbi_pipe(ctx->event_pipe); + if (r < 0) { + r = LIBUSB_ERROR_OTHER; + goto err; + } + + r = usbi_add_pollfd(ctx, ctx->event_pipe[0], POLLIN); + if (r < 0) + goto err_close_pipe; + +#ifdef USBI_TIMERFD_AVAILABLE + ctx->timerfd = timerfd_create(usbi_backend->get_timerfd_clockid(), + TFD_NONBLOCK); + if (ctx->timerfd >= 0) { + usbi_dbg("using timerfd for timeouts"); + r = usbi_add_pollfd(ctx, ctx->timerfd, POLLIN); + if (r < 0) + goto err_close_timerfd; + } else { + usbi_dbg("timerfd not available (code %d error %d)", ctx->timerfd, errno); + ctx->timerfd = -1; + } +#endif + + return 0; + +#ifdef USBI_TIMERFD_AVAILABLE +err_close_timerfd: + close(ctx->timerfd); + usbi_remove_pollfd(ctx, ctx->event_pipe[0]); +#endif +err_close_pipe: + usbi_close(ctx->event_pipe[0]); + usbi_close(ctx->event_pipe[1]); +err: + usbi_mutex_destroy(&ctx->flying_transfers_lock); + usbi_mutex_destroy(&ctx->events_lock); + usbi_mutex_destroy(&ctx->event_waiters_lock); + usbi_cond_destroy(&ctx->event_waiters_cond); + usbi_mutex_destroy(&ctx->event_data_lock); + usbi_tls_key_delete(ctx->event_handling_key); + return r; +} + +void usbi_io_exit(struct libusb_context *ctx) +{ + usbi_remove_pollfd(ctx, ctx->event_pipe[0]); + usbi_close(ctx->event_pipe[0]); + usbi_close(ctx->event_pipe[1]); +#ifdef USBI_TIMERFD_AVAILABLE + if (usbi_using_timerfd(ctx)) { + usbi_remove_pollfd(ctx, ctx->timerfd); + close(ctx->timerfd); + } +#endif + usbi_mutex_destroy(&ctx->flying_transfers_lock); + usbi_mutex_destroy(&ctx->events_lock); + usbi_mutex_destroy(&ctx->event_waiters_lock); + usbi_cond_destroy(&ctx->event_waiters_cond); + usbi_mutex_destroy(&ctx->event_data_lock); + usbi_tls_key_delete(ctx->event_handling_key); + if (ctx->pollfds) + free(ctx->pollfds); +} + +static int calculate_timeout(struct usbi_transfer *transfer) +{ + int r; + struct timespec current_time; + unsigned int timeout = + USBI_TRANSFER_TO_LIBUSB_TRANSFER(transfer)->timeout; + + if (!timeout) + return 0; + + r = usbi_backend->clock_gettime(USBI_CLOCK_MONOTONIC, ¤t_time); + if (r < 0) { + usbi_err(ITRANSFER_CTX(transfer), + "failed to read monotonic clock, errno=%d", errno); + return r; + } + + current_time.tv_sec += timeout / 1000; + current_time.tv_nsec += (timeout % 1000) * 1000000; + + while (current_time.tv_nsec >= 1000000000) { + current_time.tv_nsec -= 1000000000; + current_time.tv_sec++; + } + + TIMESPEC_TO_TIMEVAL(&transfer->timeout, ¤t_time); + return 0; +} + +/** \ingroup libusb_asyncio + * Allocate a libusb transfer with a specified number of isochronous packet + * descriptors.
