AuScanEvents(3) Library Functions Manual 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, AuEventsQueuedAfterReading, 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 determine 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 AuEventsQueuedAl- ready, 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, AuScanEvents 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. See Also AuEventsQueued, AuScanForTypedEvent, AuNextEvent. audiolib - Network Audio System C Language Interface audiolib - event handling 1.9.3 AuScanEvents(3)
