Re: Unloading sequence of GTK


If unloading glib together with gtk is acceptable you can replace the 
g_atexit function so you keep your own list and call it just before 

See (and copy/paste) this great code:

Of course this works only on *NIX (ELF executables) where symbols are
global and you can replace them with those already in memory.

Having a way to unwind all functions registered by the normal g_atexit 
would be nice.
