typedef OSStatus (*HostCallback_GetTransportState) ( void *inHostUserData, Boolean *outIsPlaying, Boolean *outTransportStateChanged, Float64 *outCurrentSampleInTimeLine, Boolean *outIsCycling, Float64 *outCycleStartBeat, Float64 *outCycleEndBeat );
I draw your attention to "outTransportStateChanged". Really? I'm supposed to keep a map of every possible client that might call me back and what I told them last time they called the callback so I can tell them that this time I'm telling them something different? Is this argument used at all? Is it a bad idea if I just return YES all the time? Why?
