295 * @func: the function to call on normal program termination.
297 * Specifies a function to be called at normal program termination.
299 * Since GLib 2.8.2, on Windows g_atexit() actually is a preprocessor
300 * macro that maps to a call to the atexit() function in the C
301 * library. This means that in case the code that calls g_atexit(),
302 * i.e. atexit(), is in a DLL, the function will be called when the
303 * DLL is detached from the program. This typically makes more sense
304 * than that the function is called when the GLib DLL is detached,
305 * which happened earlier when g_atexit() was a function in the GLib
308 * The behaviour of atexit() in the context of dynamically loaded
309 * modules is not formally specified and varies wildly.
311 * On POSIX systems, calling g_atexit() (or atexit()) in a dynamically
312 * loaded module which is unloaded before the program terminates might
313 * well cause a crash at program exit.
315 * Some POSIX systems implement atexit() like Windows, and have each
316 * dynamically loaded module maintain an own atexit chain that is
317 * called when the module is unloaded.
319 * On other POSIX systems, before a dynamically loaded module is
320 * unloaded, the registered atexit functions (if any) residing in that
321 * module are called, regardless where the code that registered them
322 * resided. This is presumably the most robust approach.
324 * As can be seen from the above, for portability it's best to avoid
325 * calling g_atexit() (or atexit()) except in the main executable of a
329 g_atexit (GVoidFunc func
