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