We can certainly add this proc - you can't.
In case I wasn't clear, I was suggesting that maybe I could just
add something like this to my code:
typedef ComponentResult (*AudioUnitSceduleParametersProc)( void *
inComponentStorage, ..... )
no you can't because it isn't implemented by any of the AUs. As I
said, you can't add this.
But I take it from your response that the
kAudioUnitScheduleParamersSelect selector is not implemented in
Apple's code yet. The very presence of such a selector in the
docs and AUComponent.h indicates the intent to add this
functionality.
Not necessarily nothing in the headers would indicate an intent to
add (or not to add) this functionality.
So the kAudioUnitScheduleParamersSelect selector is for some other
purpose, then?
Components work by defining selectors for each of their API calls.
Then, when you make a component call, the glue code includes the
selector as a part of that dispatch... Have a look in AUDispatch.cpp
(in the SDK this is in the AUPublic/AUBase directory). This is the
basic mode of operation for component dispatch.
