What happens when logging out to the applications?

[Enrico Tröger]

Hi,

I'm a bit confused.
Until now, I thought when I'm logging out and my session is saved, all
running applications get signal 15(SIGTERM) and therefore quit.

But it seems, that this is not the case. I had a look in
xfce4-session's code and if I read it correctly it calls SmsSaveYourself
(). And I guess, this function sends a kind of signal or message to
each application to ask it to quit.

How can I react on this signal in my (GTK-)application?

Regards,
Enrico

P.S.: I know, this is not really Xfce-related.
