Subject: [Gambas-devel] GB.Signal.Register() keeps program running?

Hi Benoit,

I wondered why all gb.ncurses programs (even if they don't watch any input
fds) won't quit after they finished Main(). The reason is that gb.ncurses
registers a signal handler via GB.Signal.Register() (because removing that
line from the sources makes those programs terminate after Main()).

Is this intentional? Can't we register a signal handler and anyway quit
normally after Main() if the signal didn't came?

Regards,
Tobi

Yes, you must use GB.Signal.Unregister() to remove the signal handler.

Hmm, but when? How about this: I always register the signal handler and use
GB_HOOK_WATCH to detect when nothing is watched anymore. Then, I can remove
the signal handler and the program will terminate.

The only case where this doesn't work, is when nothing is watched at all
during the process' lifetime...

Tobi
