Which signal is send? https://faq.i3wm.org/question/424/termination-of-running-apps-when-i3-quits/?answer=425#post-id-425When i3 quits, it just calls `exit(0);` which will cause X11 to terminate the session (since i3 was the first client). AFAIK, X11 does not send a signal to the applications when the session terminates. Instead, the X11 connection is closed and applications have to react accordingly.Sat, 01 Sep 2012 12:46:31 +0000https://faq.i3wm.org/question/424/termination-of-running-apps-when-i3-quits/?answer=425#post-id-425Comment by mmi for When i3 quits, it just calls <code>exit(0);</code> which will cause X11 to terminate the session (since i3 was the first client).

So i think it's better to send a TERM signal to these apps when shutting down ?Sat, 01 Sep 2012 12:51:54 +0000https://faq.i3wm.org/question/424/termination-of-running-apps-when-i3-quits/?comment=426#comment-426Comment by Michael for When i3 quits, it just calls <code>exit(0);</code> which will cause X11 to terminate the session (since i3 was the first client).

There is no guaranteed mapping between an X11 window and a UNIX process (there only is the optional `NET_WM_PID` atom). What one could do is follow the `WM_DELETE` protocol, I think the big desktop environments do it that way. OTOH, that’s a lot of code.Sat, 08 Sep 2012 23:23:57 +0000https://faq.i3wm.org/question/424/termination-of-running-apps-when-i3-quits/?comment=450#comment-450Comment by Michael for When i3 quits, it just calls <code>exit(0);</code> which will cause X11 to terminate the session (since i3 was the first client).
