Routines for Responding to Apple Events

This section describes the Apple Event Manager routines you can use to create and manage the Apple event dispatch tables, dispatch Apple events, extract information from Apple events, request user interaction, request more time to respond to Apple events, suspend and resume Apple event handling, delete descriptor records, deallocate memory for descriptor records, create and manage the coercion handler and special handler dispatch tables, and get information about the Apple Event Manager.

Because the Apple Event Manager uses the services of the Event Manager, which in turn uses the services of the PPC Toolbox, the routines described in this section may return Event Manager and PPC Toolbox result codes in addition to the Apple Event Manager result codes listed.
