/*
	'C' EXAMPLE FOR USING DEFERRED EVENTS

The following is an example of how to use deferred events within 'C'. An electronic 
copy of this example is also available from VideoLogic Regional Support Groups and 
from the VideoLogic section of the CompuServe MULTIVEN forum (GO VIDEOLOGIC).

This example is a skeleton which needs to be filled out to complete the required 
application, but it does demonstrate the required Windows communication and message 
passing process.
