You can use either the ATEventprocedure or the ATPreFlightEvent

function to notify all of the routines in the AppleTalk Transition Queue that

your AppleTalk transition has occurred. Whereas the ATEventprocedure only

calls the routines in the queue with a transition event, the

ATPreFlightEventfunction also allows each routine in the AppleTalk

Transition Queue to return a result code and other information to your calling

routine.

virtual-memory safe time. See the Memory Manager for information on

virtual memory.
