Inside Macintosh: Interapplication Communication /: Chapter 4 - Responding to Apple Events / Reference to Responding to Apple Events

Application-Defined Routines
For each Apple event your application supports, you must provide an Apple event handler. The AEProcessAppleEvent function calls one of your Apple event handlers when it processes an Apple event. An Apple event handler (MyEventHandler) should perform any action described by the Apple event, add parameters to the reply Apple event if appropriate, and return a result code.
You can also provide your own coercion handlers to coerce data to descriptor types other than those for which the Apple Event Manager provides coercion handling. The MyCoercePtr function accepts a pointer to data and returns a descriptor record, and the MyCoerceDesc function accepts a descriptor record and returns a descriptor record.
