I think you're overthinking this. This isn't pretend-multithreading with longjmp, this is just ordinary event-based programming. gtk has a big list of timers and things receiving events. It waits for events or timeouts and calls the necessary callbacks when they happen. Things like gtk_main_quit() just alter variables inside the GTK event loop.

You make lots of GTK calls inside area_event, too. Anything in there could be checking the timer. No longjmp() trickery necessary.

It's not multithreaded by design. Data visibility isn't a problem inside one thread, there's no race conditions and no magic things to be done to let other callbacks see your own changes.

If you're worried about things deadlocking inside GTK, you may be wanting to do things which probably shouldn't be inside the GTK loop. Keep a work thread that does no GTK stuff at all and let GTK do its own thing.

NAME

       libgailutil - GTK+ Accessibility Implementation Library Utilities

DESCRIPTION

       The  libgailutil  library  provides  useful accessibility functions that are common to many GTK+ components.  These functions are used when
