Subject: How does one establish a destroy function within an application?

This is most likely something that should be added to the Frequently Asked
Questions list.  The question being, How does one implement a destroy function
similar to SunView's notify_interpose_destroy_func?  This function would be
called whenever the user quits the window (most likely from the window 
menu).  Note that the implementation should work on a variety of window 
managers (mwm, twm, etc.).

I've noticed that mwm seems to send an XClientMessageEvent to the application.
The client message has an Atom name of WM_PROTOCOLS (found via XGetAtomName on
the message_type field of the message).  Twm, on the other hand, notes within
its documentation that twm will send a WM_DELETE_WINDOW if the application has
requested it through the WM_PROTOCOLS property.  How does one do this?

I'd appreciate anyones comments on how one goes about registering a destroy
function. 

Thanks!
