MyReplyFilter

A reply filter function has the following syntax:

FUNCTION MyReplyFilter (VAR event: EventRecord;
                        returnID: LongInt; 
                        transactionID: LongInt;
                        sender: AEAddressDesc): Boolean;

event

The event record for a high-level event. The next three parameters contain valid information only if the event is an Apple event.

returnID

Return ID for the Apple event.

transactionID

Transaction ID for the Apple event.

sender

Address of process that sent the Apple event.

DESCRIPTION

If your application provides a pointer to a reply filter function as a parameter to the AESend function, the reply filter function can process any high-level events that it is willing to handle while your application is waiting for a reply.

Your reply filter function should return TRUE as the function result if you want to accept the Apple event; otherwise, it should return FALSE.
