34 * @Short_description: Variables and functions to check the GLib version
36 * GLib provides version information, primarily useful in configure
37 * checks for builds that have a configure script. Applications will
38 * not typically use the features described here.
44 * The major version number of the GLib library.
46 * Like #glib_major_version, but from the headers used at
47 * application compile time, rather than from the library
48 * linked against at application run time.
54 * The minor version number of the GLib library.
56 * Like #gtk_minor_version, but from the headers used at
57 * application compile time, rather than from the library
58 * linked against at application run time.
64 * The micro version number of the GLib library.
66 * Like #gtk_micro_version, but from the headers used at
67 * application compile time, rather than from the library
68 * linked against at application run time.

348 * @func: (scope async): the function to call on normal program termination.
350 * Specifies a function to be called at normal program termination.
352 * Since GLib 2.8.2, on Windows g_atexit() actually is a preprocessor
353 * macro that maps to a call to the atexit() function in the C
354 * library. This means that in case the code that calls g_atexit(),
355 * i.e. atexit(), is in a DLL, the function will be called when the
356 * DLL is detached from the program. This typically makes more sense
357 * than that the function is called when the GLib DLL is detached,
358 * which happened earlier when g_atexit() was a function in the GLib
361 * The behaviour of atexit() in the context of dynamically loaded
362 * modules is not formally specified and varies wildly.
364 * On POSIX systems, calling g_atexit() (or atexit()) in a dynamically
365 * loaded module which is unloaded before the program terminates might
366 * well cause a crash at program exit.
368 * Some POSIX systems implement atexit() like Windows, and have each
369 * dynamically loaded module maintain an own atexit chain that is
370 * called when the module is unloaded.
372 * On other POSIX systems, before a dynamically loaded module is
373 * unloaded, the registered atexit functions (if any) residing in that
374 * module are called, regardless where the code that registered them
375 * resided. This is presumably the most robust approach.
377 * As can be seen from the above, for portability it's best to avoid
378 * calling g_atexit() (or atexit()) except in the main executable of a
382 g_atexit (GVoidFunc func

866 * separator such as "\Users\tml" or begins with the root on a drive,
867 * for example "C:\Windows". The first case also includes UNC paths
868 * such as "\\myserver\docs\foo". In all cases, either slashes or
869 * backslashes are accepted.
871 * Note that a file name relative to the current drive root does not
872 * truly specify a file uniquely over time and across processes, as
873 * the current drive is a per-process value and can be changed.
875 * File names relative the current directory on some specific drive,
876 * such as "D:foo/bar", are not interpreted as absolute by this
877 * function, but they obviously are not relative to the normal current
878 * directory as returned by getcwd() or g_get_current_dir()
879 * either. Such paths should be avoided, or need to be handled using
