AuScanEvents(3)					  AuScanEvents(3)

Name
       AuScanEvents  -	return the first event that satisfies the
       predicate

Synopsis
       #include <audio/audiolib.h>

       AuBool AuScanEvents(server, mode, dequeue, predicate, arg,
       event)
	   AuServer *server;
	   int mode;
	   AuBool dequeue;
	   AuBool (*predicate)(AuServer *,AuEvent *, AuPointer);
	   AuPointer arg;
	   AuEvent *event; /* RETURN */

Arguments
       server	 Specifies the connection to the audio server.

       mode	 Specifies  how	 far  to  look for a match.  This
		 should	   be	 one	of    these    constants:
		 AuEventsQueuedAlready,	 AuEventsQueuedAfterRead
		 ing, or AuEventsQueuedAfterFlush.

       dequeue	 Specifies if a matching event is  found,  should
		 it be removed from the queue.

       predicate Specifies the procedure that is called to deter
		 mine if an event matches the criteria.

       arg	 Specifies any additional arguments to be  passed
		 to the predicate procedure.

       event	 Returns the matching event if found.

Description
       AuScanEvents  scans  the event queue looking for the first
       event that satisfies the	 caller-supplied  predicate.   If
       mode  is	 AuEventsQueuedAlready,	 AuScanEvents only checks
       for  events  already   in   the	 queue.	   If	mode   is
       AuEventsQueuedAfterReading,  and	 a  matching  event isn't
       found already in the queue, AuScanEvents attempts to  read
       more  events out of the application's connection.  If mode
       is AuEventsQueuedAfterFlush and	a  matching  event  isn't
       already	in the queue or isn't waiting to be read, AuScan
       Events flushes the output queue and attempts to read  more
       events out of the application's connection.  If dequeue is
       AuTrue, and a matching event is found, it is removed  from
       the  queue.   The  predicate  procedure is called with the
       arguments server, event, and arg and should return  AuTrue
       to indicate a match.
