It provides basic functionalities to programs and libraries. Currently (as of October 2006) more than 30 packages make use of Gnulib.

Some people prefer to put that documentation in the .h file. In any case, it should appear in just one place unless you can ensure that the multiple copies will always remain identical. @node Header files @section Header files @cindex double inclusion of header files @cindex header file include protection It is a tradition to use CPP tricks to avoid parsing the same header file more than once, which might cause warnings. The trick is to wrap the content of the header file (say, @file{foo.h}) in a block, as in: @example #ifndef FOO_H # define FOO_H ... body of header file goes here ... #endif /* FOO_H */ @end example Whether to use @code{FOO_H} or @code{_FOO_H} is a matter of taste and style. The C89 and C99 standards reserve all identifiers that begin with an underscore and either an uppercase letter or another underscore, for any use. Thus, in theory, an application might not safely assume that @code{_FOO_H} has not already been defined by a library. On the other hand, using @code{FOO_H} will likely lead the higher risk of collisions with other symbols (e.g., @code{KEY_H}, @code{XK_H}, @code{BPF_H}, which are CPP macro constants, or @code{COFF_LONG_H}, which is a CPP macro function). Your preference may depend on whether you consider the header file under discussion as part of the application (which has its own namespace for CPP symbols) or a supporting library (that shouldn't interfere with the application's CPP symbol namespace). @cindex C++ header files @cindex Header files and C++ Adapting C header files for use in C++ applications can use another CPP trick, as in: @example # ifdef __cplusplus extern "C" @{ # endif ... body of header file goes here ... # ifdef __cplusplus @} # endif @end example The idea here is that @code{__cplusplus} is defined only by C++ implementations, which will wrap the header file in an @samp{extern "C"} block. Again, whether to use this trick is a matter of taste and style. While the above can be seen as harmless, it could be argued that the header file is written in C, and any C++ application using it should explicitly use the @samp{extern "C"} block itself. Your preference might depend on whether you consider the API exported by your header file as something available for C programs only, or for C and C++ programs alike. @subheading Include ordering When writing a gnulib module, or even in general, a good way to order the @samp{#include} directives is the following. @itemize @item First comes the #include "..." specifying the module being implemented. @item Then come all the #include <...> of system or system-replacement headers, in arbitrary order. @item Then come all the #include "..." of gnulib and private headers, in arbitrary order. @end itemize @node Out of memory handling @section Out of memory handling @cindex Out of Memory handling @cindex Memory allocation failure The GSS API does not have a standard error code for the out of memory error condition. Instead of adding a non-standard error code, this library has chosen to adopt a different strategy. Out of memory handling happens in rare situations, but performing the out of memory error handling after almost all API function invocations pollute your source code and might make it harder to spot more serious problems. The strategy chosen improves code readability and robustness. @cindex Aborting execution For most applications, aborting the application with an error message when the out of memory situation occurs is the best that can be wished for. This is how the library behaves by default. @vindex xalloc_fail_func However, we realize that some applications may not want to have the GSS library abort execution in any situation. The GSS library supports a hook to let the application regain control and perform its own cleanups when an out of memory situation has occurred. The application can define a function (having a @code{void} prototype, i.e., no return value and no parameters) and set the library variable @code{xalloc_fail_func} to that function. The variable should be declared as follows. @example extern void (*xalloc_fail_func) (void); @end example The GSS library will invoke this function if an out of memory error occurs. Note that after this the GSS library is in an undefined state, so you must unload or restart the application to continue call GSS library functions. The hook is only intended to allow the application to log the situation in a special way. Of course, care must be taken to not allocate more memory, as that will likely also fail. @node Library version handling @section Library version handling The module @samp{check-version} can be useful when your gnulib application is a system library. You will typically wrap the call to the @code{check_version} function through a library API, your library header file may contain: @example #define STRINGPREP_VERSION "0.5.18" ... extern const char *stringprep_check_version (const char *req_version); @end example To avoid ELF symbol collisions with other libraries that use the @samp{check-version} module, add to @file{config.h} through a AC_DEFINE something like: @example AC_DEFINE(check_version, stringprep_check_version, [Rename check_version.]) @end example The @code{stringprep_check_version} function will thus be implemented by the @code{check_version} module. There are two uses of the interface. The first is a way to provide for applications to find out the version number of the library it uses. The application may contain diagnostic code such as: @example printf ("Stringprep version: header %s library %s", STRINGPREP_VERSION, stringprep_check_version (NULL)); @end example Separating the library and header file version can be useful when searching for version mismatch related problems. The second uses is as a rudimentary test of proper library version, by making sure the application get a library version that is the same, or newer, than the header file used when building the application. This doesn't catch all problems, libraries may change backwards incompatibly in later versions, but enable applications to require a certain minimum version before it may proceed. Typical uses look like: @example /* Check version of libgcrypt. */ if (!gcry_check_version (GCRYPT_VERSION)) die ("version mismatch\n"); @end example @node Windows sockets @section Windows sockets There are several issues when building applications that should work under Windows. The most problematic part is for applications that use sockets. Hopefully, we can add helpful notes to this section that will help you port your application to Windows using gnulib. @subsection Getaddrinfo and WINVER This was written for the getaddrinfo module, but may be applicable to other functions too. The getaddrinfo function exists in ws2tcpip.h and -lws2_32 on Windows XP. The function declaration is present if @code{WINVER >= 0x0501}. Windows 2000 does not have getaddrinfo in its @file{WS2_32.dll}. Thus, if you want to assume Windows XP or later, you can add AC_DEFINE(WINVER, 0x0501) to avoid compiling to (partial) getaddrinfo implementation. If you want to support Windows 2000, don't do anything, but be aware that gnulib will use its own (partial) getaddrinfo implementation even on Windows XP. Currently the code does not attempt to determine if the getaddrinfo function is available during runtime. Todo: Make getaddrinfo.c open the WS2_32.DLL and check for the getaddrinfo symbol and use it if present, otherwise fall back to our own implementation. @node Libtool and Windows @section Libtool and Windows If you want it to be possible to cross-compile your program to MinGW and you use Libtool, you need to put: @example AC_LIBTOOL_WIN32_DLL @end example in your @file{configure.ac}. This sets the correct names for the @code{OBJDUMP}, @code{DLLTOOL}, and @code{AS} tools for the build. If you are building a library, you will also need to pass @code{-no-undefined} to make sure Libtool produces a DLL for your library. From a @file{Makefile.am}: @example libgsasl_la_LDFLAGS += -no-undefined @end example @node License Texinfo sources @section License Texinfo sources Gnulib provides copies of the GNU GPL, GNU LGPL, and GNU FDL licenses in Texinfo form. (The master location is @url{http://www.gnu.org/licenses/}). These Texinfo documents do not have any node names and structures built into them; for your manual, you should @code{@@include} them in an appropriate @code{@@node}. The conventional name for the GPL node is @samp{Copying} and for the FDL @samp{GNU Free Documentation License}. The LGPL doesn't seem to have a conventional node name. Of course the license texts themselves should not be changed at all. @node Build robot for gnulib @section Build robot for gnulib To simplify testing on a wide set of platforms, gnulib is built on many platforms every day and the results are uploaded to: @url{http://autobuild.josefsson.org/gnulib/} If you wish to help the gnulib development effort with build logs for your favorite platform, you may perform these steps: @enumerate @item Create gnulib directory On a machine with recent automake, autoconf, m4 installed and with a gnulib git or cvs checkout (typically a Linux machine), use @example gnulib-tool --create-megatestdir --with-tests --dir=..." @end example Note: The created directory uses ca. 512 MB on disk. @item Transfer gnulib directory Transfer this directory to a build machine (HP-UX, Cygwin, or whatever). Often it is easier to transfer one file, and this can be achieved by running, inside the directory the following commands: @example ./configure make dist @end example And then transferring the @file{dummy-0.tar.gz} file. @item Build modules On the build machine, run ./do-autobuild (or "nohup ./do-autobuild"). It creates a directory 'logs/' with a log file for each module. @item Submit build logs Submit each log file to Simon's site, either through a @example mail `echo gnulib__at__autobuild.josefsson.org | sed -e s/__at__/@@/` @end example or through netcat @example autobuild-submit logs/* @end example @end enumerate @node Header File Substitutes @chapter ISO C and POSIX Header File Substitutes This
