A Cygwin emacs user has asked
(http://debbugs.gnu.org/cgi/bugreport.cgi?bug=23483) whether emacs can
auto-save files when he shuts down Windows from the Start Menu. Is
there a way for a Cygwin process to listen for Windows system shutdown
messages?
This seems entirely possible using the Win32 API.
For emacs-w32, it's probably straightforward to handle WM_ENDSESSION in
the message loop similarly to WM_CLOSE
This was indeed straightforward, so I went ahead and did it. But I
didn't try to do anything for emacs-X11 and emacs-nox because it's more
complicated, and...
But I'm not sure that's the best approach, or if wouldn't be more
appropriate to arrange for SIGTERM to be sent to emacs (or whatever) by
mintty or the X server when an WM_ENDSESSION is received...
... I hope Someone will do this.
