When the session manage wishes to shut down (either for a logout or for the

The workspace notification center sends that notification to all the
applications in the session, and they can respond by closing down cleanly.
Is there a fallback for applications that don't explicitly observe this
notification (like passing terminate: to NSApplication instance) ? What
about
OpenStep or Mac OS X - do they have something like that ?
Not that I know of ... observing the notification seems to be the 'graceful'
way to shut down.
Internally, an application receiving a power-off notification would usually
call its own -terminate method to shut down, but you can't generally call
that from outside the application. So if an application ignores the power
off notification, I guess you really have to use the kill() system call to
stop it in a less graceful manner.
