In theory, yes ... the gui library has the NSWorkspace class ... which is 
essentially the session management facility.
When the session manage wishes to shut down (either for a logout or for the 
machine shutting down), it should post an 
NSWorkspaceWillPowerOffNotification to the workspace notificationCenter.  
The workspace notification center sends that notification to all the 
applications in the session, and they can respond by closing down cleanly.

In practice, I think most applications probably ignore the notification 
(since we don't actually have a standard session manager to send the 
notification ... except perhaps GSWorkspace.app, which might send an 
NSWorkspaceWillPowerOffNotification when it is shut down).
