Whether to use @code{FOO_H} or @code{_FOO_H} is a matter of taste and
-style. The C99 standard reserve all identifiers that begin with an
+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{COFF_LONG_H} which is a CPP
-macro function). Your preference may depeend on whether you consider
+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 interfer with the application's CPP symbol namespace).

+The idea here is that @code{__cplusplus} is defined only by C++

that the header file is written in C, and any C++ application using it

-@node ctime
-@section ctime
-@findex ctime

-The @code{ctime} function need not be reentrant, and consequently is
-not required to be thread safe. Implementations of @code{ctime}
-typically write the time stamp into static buffer. If two threads
-call @code{ctime} at roughly the same time, you might end up with the
-wrong date in one of the threads, or some undefined string. There is
-a re-entrant interface @code{ctime_r}, that take a pre-allocated
-buffer and length of the buffer, and return @code{NULL} on errors.
-The input buffer should be at least 26 bytes in size. The output
-string is locale-independent. However, years can have more than 4
-digits if @code{time_t} is sufficiently wide, so the length of the
-required output buffer is not easy to determine. Increasing the
-buffer size when @code{ctime_r} return @code{NULL} is not necessarily
-sufficient. The @code{NULL} return value could mean some other error
-condition, which will not go away by increasing the buffer size.
-
-A more flexible function is @code{strftime}. However, note that it is
-locale dependent.
+@subheading Include ordering
+When writing a gnulib module, or even in general, a good way to order
+the @samp{#include} directives is the following.
-@node inet_ntoa
-@section inet_ntoa
-@findex inet_ntoa
-
-The @code{inet_ntoa} function need not be reentrant, and consequently
-is not required to be thread safe. Implementations of

-If two threads call @code{inet_ntoa} at roughly the same time, you
-might end up with the wrong date in one of the threads, or some
-undefined string. Further, @code{inet_ntoa} is specific for
-@acronym{IPv4} addresses.
-
-A protocol independent function is @code{inet_ntop}.

+@node Library version handling
+@section Library version handling
-Run @samp{gnulib-tool --help}, and use the source.
-@command{gnulib-tool} is the way to import Gnulib modules.
+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:
-@menu
-* Initial import:: First import of Gnulib modules.
-* Importing updated files:: Subsequent imports.
-* Finishing touches:: Simplifying imports.
-@end menu
+@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:
-@node Initial import
-@section Initial import
-@cindex initial import
+@example
+AC_DEFINE(check_version, stringprep_check_version,
+ [Rename check_version.])
+@end example
-Gnulib assumes your project uses Autoconf and Automake. Invoking
-@samp{gnulib-tool --import} will copy source files, create a
-@file{Makefile.am} to build them, and generate a @file{gnulib.m4} with
-Autoconf M4 macro declarations used by @file{configure.ac}.
+The @code{stringprep_check_version} function will thus be implemented
+by the @code{check_version} module.
-Our example will be a library that uses Autoconf, Automake and
-Libtool. It calls @code{strdup}, and you wish to use gnulib to make
-the package portable to C89 (which doesn't have @code{strdup}).
+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
-~/src/libfoo$ gnulib-tool --import strdup
-Module list with included dependencies:
- strdup
-File list:
- lib/strdup.c
- lib/strdup.h
- m4/onceonly_2_57.m4
- m4/strdup.m4
-Creating ./lib/Makefile.am...
-Creating ./m4/gnulib.m4...
-Finished.
-
-Don't forget to add "lib/Makefile"
-to AC_CONFIG_FILES in "./configure.ac" and to mention
-"lib" in SUBDIRS in some Makefile.am.
-~/src/libfoo$
+ printf ("Stringprep version: header %s library %s",
+ STRINGPREP_VERSION,
+ stringprep_check_version (NULL));
@end example
-By default, the source code is copied into @file{lib/} and the M4
-macros in @file{m4/}. You can override these paths by using
-@code{--source-base=DIRECTORY} and @code{--m4-base=DIRECTORY}, or by
-adding @samp{gl_SOURCE_BASE(DIRECTORY)} and
-@samp{gl_M4_BASE(DIRECTORY)} to your @file{configure.ac}.
-
-@code{gnulib-tool} will overwrite any pre-existing files, in
-particular @file{Makefile.am}. Unfortunately, separating the
-generated @file{Makefile.am} content (for building the gnulib library)
-into a separate file, say @file{gnulib.mk}, that could be included
-by your handwritten @file{Makefile.am} is not possible, due to how
-variable assignments are handled by Automake.
-
-Consequently, it can be a good idea to chose directories that are not
-already used by your projects, to separate gnulib imported files from
-your own files. This approach can also be useful if you want to avoid
-conflicts between other tools (e.g., @code{getextize} that also copy
-M4 files into your package. Simon Josefsson successfully uses a source
-base of @file{gl/}, and a M4 base of @file{gl/m4/}, in several
-packages.
-
-A few manual steps are required to finish the initial import.
-
-First, you need to make sure Autoconf can find the macro definitions
-in @file{gnulib.m4}. Use the @code{ACLOCAL_AMFLAGS} specifier in your
-top-level @file{Makefile.am} file, as in:
+Separating the library and header file version can be useful when
+searching for version mismatch related problems.
-@example
-ACLOCAL_AMFLAGS = -I m4
-@end example
+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.
-Naturally, replace @file{m4} with the value from @code{--m4-base} or
-@code{gl_M4_BASE}. If the M4 base is @file{gl/m4} you would use:
+Typical uses look like:
@example
-ACLOCAL_AMFLAGS = -I gl/m4
+ /* Check version of libgcrypt. */
+ if (!gcry_check_version (GCRYPT_VERSION))
+ die ("version mismatch\n");
@end example
-You are now ready to call the M4 macros in @code{gnulib.m4} from
-@file{configure.ac}. The macro @code{gl_EARLY} must be called as soon
-as possible after verifying that the C compiler is working.
-Typically, this is immediately after @code{AC_PROG_CC}, as in:
-@example
-...
-AC_PROG_CC
-gl_EARLY
-...
-@end example
+@node Windows sockets
+@section Windows sockets
-The core part of the gnulib checks are done by the macro
-@code{gl_INIT}. Place it further down in the file, typically where
-you normally check for header files or functions. Or in a separate
-section with other gnulib statements, such as @code{gl_SOURCE_BASE}.
-For example:
+There are several issues when building applications that should work
+under Windows. The most problematic part is for applications that use
+sockets.
-@example
-...
-# For gnulib.
-gl_INIT
-...
-@end example
+Hopefully, we can add helpful notes to this section that will help you
+port your application to Windows using gnulib.
-You must also make sure that the gnulib library is built. Add the
-@code{Makefile} in the gnulib source base directory to
-@code{AC_CONFIG_FILES}, as in:
+@subsection Getaddrinfo and WINVER
-@example
-AC_CONFIG_FILES(... lib/Makefile ...)
-@end example
+This was written for the getaddrinfo module, but may be applicable to
+other functions too.
-If your gnulib source base is @file{gl}, you would use:
+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}.
-@example
-AC_CONFIG_FILES(... gl/Makefile ...)
-@end example
+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
-You must also make sure that @code{make} work in the gnulib directory.
-Add the gnulib source base directory to a @code{SUBDIRS} Makefile.am
-statement, as in:
+If you want it to be possible to cross-compile your program to MinGW
+and you use Libtool, you need to put:
@example
-SUBDIRS = lib
+AC_LIBTOOL_WIN32_DLL
@end example
-or if you, more likely, already have a few entries in @code{SUBDIRS},
-you can add something like:
+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
-SUBDIRS += lib
+libgsasl_la_LDFLAGS += -no-undefined
@end example
-If you are using a gnulib source base of @code{gl}, you would use:
+
+@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,

+@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
-SUBDIRS += gl
+gnulib-tool --create-megatestdir --with-tests --dir=..."
@end example
-Finally, you have add C flags and LD flags, so that you can make use
-of the gnulib library. For 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
-...
-AM_CPPFLAGS = -I$(top_srcdir)/lib
-...
-LIBADD = lib/libgnu.la
-...
+./configure
+make dist
@end example
-Don't forget to @code{#include} the various header files. In this
-example, you would need to make sure that @samp{#include <strdup.h>}
-is evaluated when compiling all source code files, that want to make
-use of @code{strdup}.
+And then transferring the @file{dummy-0.tar.gz} file.
+
+@item Build modules
+On the build machine, run ./do-autobuild (or "nohup ./do-autobuild").
+It creates a directory 'logs/' with a log file for each module.
-@node Importing updated files
-@section Importing updated files
+@item Submit build logs
-From time to time, you may want to invoke @samp{gnulib-tool --import}
-to update the files in your package. Once you have set up your
-package for gnulib, this step is quite simple. For example:
+Submit each log file to Simon's site, either through a
@example
-~/src/libfoo$ gnulib-tool --import --source-base gl --m4-base gl/m4 strdup
-Module list with included dependencies:

- lib/strdup.h
- m4/onceonly_2_57.m4
- m4/strdup.m4
-Creating ./lib/Makefile.am...

-
-Don't forget to add "lib/Makefile"

+@node POSIX Substitutes Library
+@chapter Building the ISO C and POSIX Substitutes
-Invoking @samp{gnulib-tool --import} with the proper parameters (e.g.,
-@samp{--m4-base gl/m4}) and list of modules (e.g., @samp{strdup
-snprintf getline minmax}) can be tedious. To simplify this procedure,
-you may put the command line parameters in your @file{configure.ac}.
-For example:
+This section shows a radically different way to use Gnulib.
-@example
-...
-AC_PROG_CC
-gl_EARLY
-...
-# For gnulib.
-gl_SOURCE_BASE(gl)
-gl_M4_BASE(gl/m4)
-gl_LIB(libgl)
-gl_MODULES(getopt progname strdup dummy exit error getpass-gnu getaddrinfo)
-gl_INIT
-...
-@end example
+You can extract the ISO C / POSIX substitutes part of gnulib by running
+the command
+@smallexample
+gnulib-tool --create-testdir --source-base=lib \
+ --dir=/tmp/posixlib `posix-modules`
+@end smallexample
+
+@noindent
+The command @samp{posix-modules} is found in the same directory as
+@code{gnulib-tool}.
+
+The resulting directory can be built on a particular platform,
+independently of the program being ported. Then you can configure and
+build any program, by setting @code{CPPFLAGS} and @code{LDFLAGS} at
+configure time accordingly: set @code{CPPFLAGS="-I.../posixlib/lib"}, plus
+any essential type definitions and flags that you find in
+@code{.../posixlib/config.h}, and set
+@code{LDFLAGS=".../posixlib/lib/libgnu.a"}.
-This illustrate all macros defined in @file{gnulib.m4}. With the
-above, importing new files are as simple as running @samp{gnulib-tool
---import} with no additional parameters.
+This way of using Gnulib is useful when you don't want to modify the program's
+source code, or when the program uses a mix between C and C++ sources
+(requiring separate builds of the @code{posixlib} for the C compiler and
+for the C++ compiler).
+

+@node Function Substitutes
+@chapter ISO C and POSIX Function Substitutes
+
+This chapter describes which functions and function-like macros specified by
+ISO C or POSIX are substituted by Gnulib, which portability pitfalls are
+fixed by Gnulib, and which (known) portability problems are not worked around
+by Gnulib.
+
+The notation ``Gnulib module: ---'' means that Gnulib does not provide a
+module providing a substitute for the function. When the list
+``Portability problems not fixed by Gnulib'' is empty, such a module is
+not needed: No portability problems are known. Otherwise, it indicates
+that such a module would be useful but is not available: Noone so far
+found this function important enough to contribute a substitute for it.
+If you need this particular function, you may write to
+@code{<bug-gnulib at gnu dot org>}.
