188 * Specifies a function to be called at normal program termination.
190 * Since GLib 2.8.2, on Windows g_atexit() actually is a preprocessor
191 * macro that maps to a call to the atexit() function in the C
192 * library. This means that in case the code that calls g_atexit(),
193 * i.e. atexit(), is in a DLL, the function will be called when the
194 * DLL is detached from the program. This typically makes more sense
195 * than that the function is called when the GLib DLL is detached,
196 * which happened earlier when g_atexit() was a function in the GLib
199 * The behaviour of atexit() in the context of dynamically loaded
200 * modules is not formally specified and varies wildly.
202 * On POSIX systems, calling g_atexit() (or atexit()) in a dynamically
203 * loaded module which is unloaded before the program terminates might
204 * well cause a crash at program exit.
206 * Some POSIX systems implement atexit() like Windows, and have each
207 * dynamically loaded module maintain an own atexit chain that is
208 * called when the module is unloaded.
210 * On other POSIX systems, before a dynamically loaded module is
211 * unloaded, the registered atexit functions (if any) residing in that
212 * module are called, regardless where the code that registered them
213 * resided. This is presumably the most robust approach.
215 * As can be seen from the above, for portability it's best to avoid
216 * calling g_atexit() (or atexit()) except in the main executable of a
