I am a bit confused about implementing a subclass of an IOAudioEngine...
According to the sample code, my subclass should define
performAudioEngineStart(), a virtual method, which will be called when
the audio engine is supposed to start.
However, in the online HTML docs, there is no mention of
performAudioEngineStart() (though it *is* in the header), but there
*is* startAudioEngine() (in the headers *and* the docs). And in the
description of startAudioEngine() it says that it "must be overridden
by subclass" and that _setState(kAudioEngineRunning) must be called...
Currently, I have a mostly-working driver that uses
performAudioEngineStart() but not startAudioEngine(), so apparently the
latter is not necessary, though the docs say it is...
Can anyone direct me to some clarification of what's going on here?
Thanks!
-Michael
