GNU LESSER GENERAL PUBLIC LICENSE - Version 2.1, February 1999 - - Copyright (C) 1991, 1999 Free Software Foundation, Inc. - 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA - Everyone is permitted to copy and distribute verbatim copies - of this license document, but changing it is not allowed. - -[This is the first released version of the Lesser GPL. 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.

This file is offered as-is, -without warranty of any kind. - -Basic Installation -================== - - Briefly, the shell command `./configure && make && make install' -should configure, build, and install this package. The following -more-detailed instructions are generic; see the `README' file for -instructions specific to this package. Some packages provide this -`INSTALL' file but do not implement all of the features documented -below. The lack of an optional feature in a given package is not -necessarily a bug. More recommendations for GNU packages can be found -in *note Makefile Conventions: (standards)Makefile Conventions. - - 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, generally using the just-built uninstalled binaries. - - 4. Type `make install' to install the programs and any data files and - documentation. When installing into a prefix owned by root, it is - recommended that the package be configured and built as a regular - user, and only the `make install' phase executed with root - privileges. - - 5. Optionally, type `make installcheck' to repeat any self-tests, but - this time using the binaries in their final installed location. - This target does not install anything. Running this target as a - regular user, particularly if the prior `make install' required - root privileges, verifies that the installation completed - correctly. - - 6. 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. - - 7. Often, you can also type `make uninstall' to remove the installed - files again. In practice, not all packages have tested that - uninstallation works correctly, even though it is required by the - GNU Coding Standards. - - 8. Some packages, particularly those that use Automake, provide `make - distcheck', which can by used by developers to test that all other - targets like `make install' and `make uninstall' work correctly. - This target is generally not run by end users. - -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 `..'. This -is known as a "VPATH" build. - - 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. - - On MacOS X 10.5 and later systems, you can create libraries and -executables that work on multiple system types--known as "fat" or -"universal" binaries--by specifying multiple `-arch' options to the -compiler but only a single `-arch' option to the preprocessor. Like -this: - - ./configure CC="gcc -arch i386 -arch x86_64 -arch ppc -arch ppc64" \ - CXX="g++ -arch i386 -arch x86_64 -arch ppc -arch ppc64" \ - CPP="gcc -E" CXXCPP="g++ -E" - - This is not guaranteed to produce working output in all cases, you -may have to build one architecture at a time and combine the results -using the `lipo' tool if you have problems. - -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', where PREFIX must be an -absolute file name. - - 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. In general, the -default for these options is expressed in terms of `${prefix}', so that -specifying just `--prefix' will affect all of the other directory -specifications that were not explicitly provided. - - The most portable way to affect installation locations is to pass the -correct locations to `configure'; however, many packages provide one or -both of the following shortcuts of passing variable assignments to the -`make install' command line to change installation locations without -having to reconfigure or recompile. - - The first method involves providing an override variable for each -affected directory. For example, `make install -prefix=/alternate/directory' will choose an alternate location for all -directory configuration variables that were expressed in terms of -`${prefix}'. Any directories that were specified during `configure', -but not in terms of `${prefix}', must each be overridden at install -time for the entire installation to be relocated. The approach of -makefile variable overrides for each directory variable is required by -the GNU Coding Standards, and ideally causes no recompilation. -However, some platforms have known limitations with the semantics of -shared libraries that end up requiring recompilation when using this -method, particularly noticeable in packages that use GNU Libtool. - - The second method involves providing the `DESTDIR' variable. For -example, `make install DESTDIR=/alternate/directory' will prepend -`/alternate/directory' before all installation names. The approach of -`DESTDIR' overrides is not required by the GNU Coding Standards, and -does not work on platforms that have drive letters. On the other hand, -it does better at avoiding recompilation issues, and works well even -when some directory options were not specified in terms of `${prefix}' -at `configure' time. - -Optional Features -================= - - 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'. - - 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. - - Some packages offer the ability to configure how verbose the -execution of `make' will be. For these packages, running `./configure ---enable-silent-rules' sets the default to minimal output, which can be -overridden with `make V=1'; while running `./configure ---disable-silent-rules' sets the default to verbose, which can be -overridden with `make V=0'. - -Particular systems -================== - - On HP-UX, the default C compiler is not ANSI C compatible. If GNU -CC is not installed, it is recommended to use the following options in -order to use an ANSI C compiler: - - ./configure CC="cc -Ae -D_XOPEN_SOURCE=500" - -and if that doesn't work, install pre-built binaries of GCC for HP-UX. - - HP-UX `make' updates targets which have the same time stamps as -their prerequisites, which makes it generally unusable when shipped -generated files such as `configure' are involved. Use GNU `make' -instead. - - On OSF/1 a.k.a. Tru64, some versions of the default C compiler cannot -parse its `' header file. The option `-nodtk' can be used as -a workaround. If GNU CC is not installed, it is therefore recommended -to try - - ./configure CC="cc" - -and if that doesn't work, try - - ./configure CC="cc -nodtk" - - On Solaris, don't put `/usr/ucb' early in your `PATH'. This -directory contains several dysfunctional programs; working variants of -these programs are available in `/usr/bin'. So, if you need `/usr/ucb' -in your `PATH', put it _after_ `/usr/bin'. - - On Haiku, software installed for all users goes in `/boot/common', -not `/usr/local'. It is recommended to use the following options: - - ./configure --prefix=/boot/common - -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 limitation. Until the limitation is lifted, you can use -this workaround: - - CONFIG_SHELL=/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 all of the options to `configure', and exit. - -`--help=short' -`--help=recursive' - Print a summary of the options unique to this package's - `configure', and exit. The `short' variant lists options used - only in the top level, while the `recursive' variant lists options - also present in any nested packages. - -`--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. - -`--prefix=DIR' - Use DIR as the installation prefix. *note Installation Names:: - for more details, including other options available for fine-tuning - the installation locations. - -`--no-create' -`-n' - Run the configure checks, but stop before creating any output - files. - -`configure' also accepts some other, not widely useful, options. Run -`configure --help' for more details. diff --git a/Externals/libusb/INSTALL_WIN.txt b/Externals/libusb/INSTALL_WIN.txt deleted file mode 100644 index a37d643a9b..0000000000 --- a/Externals/libusb/INSTALL_WIN.txt +++ /dev/null @@ -1,73 +0,0 @@ -Installation Instructions for Windows -************************************* - -If you are compiling for MinGW or cygwin, please refer to the INSTALL file. - -If you are using Microsoft Visual Studio: -- Open the relevant solution file in /msvc: - libusb.dsw for MSVC6, libusb_2005.sln for Visual Studio 2005 or 2008, - libusb_2010.sln for Visual Studio 2010, - libusb_2012.sln for Visual Studio 2012 or later, - libusb_wince.sln for Windows CE support in Visual Studio 2005. -- If you want to debug the library, uncomment the ENABLE_DEBUG_LOGGING define - in msvc\config.h -- Select your configuration and compile the project - -Note that if you are using Visual Studio Express, you may have to install the -Windows SDK to be able to compile the 64 bit version of the library. - -If you are using the freely available Windows DDK/WDK (Driver Development Kit) -- If you want to debug the library, uncomment the ENABLE_DEBUG_LOGGING define - in msvc\config.h -- Open one of the relevant Free Build or Checked Build prompt for your target - platform -- Navigate to the msvc\ directory where the ddk_build.cmd file is located, and - run 'ddk_build' -- To produce a DLL rather than a static library, use: 'ddk_build DLL' -- To produce a static library that uses LIBCMT[d] instead of MSVCRT[d] (/MT[d] - vs /MD[d] in Visual Studio) use: 'ddk_build /MT' - -Note that using the Windows DDK, it is possible to compile both the 32 and 64 -bit versions of the library. - -If you are building for Windows CE then you will need the Windows CE Standard 5.00 SDK. - -Destination directories -*********************** - -The 32 bit binaries compiled either from Visual Studio or the DDK are placed in -a Win32\ directory at the root of the library -The 64 bit binaries are placed in an x64\ directory -Windows CE binaries are placed in one of the following directories, depending -on the target processor: ARMV4I, MIPSII, MIPSII_FP, MIPSIV, MIPSIV_FP, SH4 or x86. - - -Troubleshooting -*************** - -If the compilation process complains about missing libraries, ensure that the -default library paths for your project points to the relevant directories. -If needed, these libraries can be obtained by installing either the latest -Windows SDK or the DDK (Links provided at the end of this file). - -For Windows CE it is necessary to install the CE USB Kernel Wrapper driver for -libusb to function on a device. - -Links -***** - -Additional information related to the Windows backend: - http://windows.libusb.info - -Latest Windows Driver (Development) Kit (WDK): - http://www.microsoft.com/downloads/details.aspx?displaylang=en&FamilyID=36a2630f-5d56-43b5-b996-7633f2ec14ff - -Latest Microsoft Windows SDK: - http://www.microsoft.com/downloads/details.aspx?displaylang=en&FamilyID=c17ba869-9671-4330-a63e-1fd44e0e2505 - -Windows CE Standard 5.00 SDK: - http://www.microsoft.com/en-gb/download/details.aspx?id=17310 - -Windows CE USB Kernel Wrapper Driver: - https://github.com/RealVNC/CEUSBKWrapper - diff --git a/Externals/libusb/Makefile.am b/Externals/libusb/Makefile.am deleted file mode 100644 index 0155625ac1..0000000000 --- a/Externals/libusb/Makefile.am +++ /dev/null @@ -1,28 +0,0 @@ -AUTOMAKE_OPTIONS = dist-bzip2 no-dist-gzip -ACLOCAL_AMFLAGS = -I m4 -DISTCLEANFILES = libusb-1.0.pc -EXTRA_DIST = TODO PORTING msvc libusb/libusb-1.0.def libusb/version_nano.h \ - examples/getopt/getopt.c examples/getopt/getopt1.c examples/getopt/getopt.h \ - android Xcode -SUBDIRS = libusb doc - -if BUILD_EXAMPLES -SUBDIRS += examples -endif - -if BUILD_TESTS -SUBDIRS += tests -endif - -pkgconfigdir=$(libdir)/pkgconfig -pkgconfig_DATA=libusb-1.0.pc - -.PHONY: dist-up - -reldir = .release/$(distdir) -dist-up: dist - rm -rf $(reldir) - mkdir -p $(reldir) - cp $(distdir).tar.bz2 $(reldir) - rsync -rv $(reldir) frs.sourceforge.net:/home/frs/project/l/li/libusb/libusb-1.0/ - rm -rf $(reldir) diff --git a/Externals/libusb/NEWS b/Externals/libusb/NEWS deleted file mode 100644 index 07695abc1e..0000000000 --- a/Externals/libusb/NEWS +++ /dev/null @@ -1,2 +0,0 @@ -For the latest libusb news, please refer to the ChangeLog file, or visit: -http://libusb.info diff --git a/Externals/libusb/PORTING b/Externals/libusb/PORTING deleted file mode 100644 index fa9ec1e58d..0000000000 --- a/Externals/libusb/PORTING +++ /dev/null @@ -1,94 +0,0 @@ -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).

For more info, see the - * libusb homepage. - * - * 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 - * libusb-devel mailing list. - * - * 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 USB 3.0 - * Specification 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_option(ctx, LIBUSB_OPTION_LOG_LEVEL, level), 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_option(ctx, LIBUSB_OPTION_LOG_LEVEL, level) 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_option(ctx, LIBUSB_OPTION_LOG_LEVEL, level) parameter. When this - * environment variable is set, the message logging verbosity level is fixed - * and libusb_set_option(ctx, LIBUSB_OPTION_LOG_LEVEL, level) effectively does - * nothing. - * - * libusb can be compiled without any logging functions, useful for embedded - * systems. In this case, libusb_set_option(ctx, LIBUSB_OPTION_LOG_LEVEL, level) - * 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_option(ctx, LIBUSB_OPTION_LOG_LEVEL, level) 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 fork Fork considerations - * - * libusb is not designed to work across fork() calls. Depending on - * the platform, there may be resources in the parent process that are not - * available to the child (e.g. the hotplug monitor thread on Linux). In - * addition, since the parent and child will share libusb's internal file - * descriptors, using libusb in any way from the child could cause the parent - * process's \ref libusb_context to get into an inconsistent state. - * - * On Linux, libusb's file descriptors will be marked as CLOEXEC, which means - * that it is safe to fork() and exec() without worrying about the child - * process needing to clean up state or having access to these file descriptors. - * Other platforms may not be so forgiving, so consider yourself warned! - * - * \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 - * after 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_option() 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 context 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 -

The following sequence of function calls will be suitable - * for almost all scenarios and does not require you to have such a deep - * understanding of the resource management issues: - * \code -// discover devices -libusb_device **list; -libusb_device *found = NULL; -ssize_t cnt = libusb_get_device_list(NULL, &list); -ssize_t i = 0; -int err = 0; -if (cnt < 0) - error(); - -for (i = 0; i < cnt; i++) { - libusb_device *device = list[i]; - if (is_interesting(device)) { - found = device; - break; - } -} - -if (found) { - libusb_device_handle *handle; - - err = libusb_open(found, &handle); - if (err) - error(); - // etc -} - -libusb_free_device_list(list, 1); -\endcode - * - * The two important points: - * - You asked libusb_free_device_list() to unreference the devices (2nd - * parameter) - * - You opened the device before freeing the list and unreferencing the - * devices - * - * If you ended up with a handle, you can now proceed to perform I/O on the - * device. - * - * \section devshandles Devices and device handles - * libusb has a concept of a USB device, represented by the - * \ref libusb_device opaque type. 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 device handle - * (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.

This page aims to - * introduce the two in order to help you decide which one is more suitable - * for your application. 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: - * -# Allocation: allocate a libusb_transfer - * -# Filling: populate the libusb_transfer instance with information - * about the transfer you wish to perform - * -# Submission: ask libusb to submit the transfer - * -# Completion handling: examine transfer results in the - * libusb_transfer structure - * -# Deallocation: 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. - * - * Important Note: 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 libusb_transfer 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 plus 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 length was 12, then you - * should expect an actual_length 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. - * - * Note: 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 any future platforms supported by libusb which may have time-based - * event requirements). 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 serializing 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, myfunc() - * will only realise that the transfer has completed on the next iteration of - * the loop, up to 120 seconds later. 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 event waiters 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 | TFD_CLOEXEC); - 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); - 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) { - timerclear(&transfer->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.

    - *
  1. Download the latest \c strerror.c from:
    - * https://raw.github.com/libusb/libusb/master/libusb/strerror.c
    2. - *
  2. Open the file in an UTF-8 capable editor
    3. - *
  3. Add the 2 letter ISO 639-1 - * code for your locale at the end of \c usbi_locale_supported[]
    - * Eg. for Chinese, you would add "zh" so that: - * \code... usbi_locale_supported[] = { "en", "nl", "fr" };\endcode - * becomes: - * \code... usbi_locale_supported[] = { "en", "nl", "fr", "zh" };\endcode
    4. - *
  4. Copy the { / * English (en) * / ... } section and add it at the end of \c usbi_localized_errors
    - * Eg. for Chinese, the last section of \c usbi_localized_errors could look like: - * \code - * }, { / * Chinese (zh) * / - * "Success", - * ... - * "Other error", - * } - * };\endcode
    5. - *
  5. Translate each of the English messages from the section you copied into your language
    6. - *
  6. Save the file (in UTF-8 format) and send it to \c libusb-devel\@lists.sourceforge.net
    7. - *
