I think that stuff is the polling versus callback scheduling when
talking to the audio device. If you look in the audio preferences,
there is a check box that says "use callbacks". My guess is that will
enable m_callbackscheduler().

Hi all,
I've been stepping through the pd source and trying to understand
the scheduling system, would anyone who knows mind helping me to
this effect?
There are two options that m_mainloop() has for scheduling,
m_pollingscheduler() and m_callbackscheduler(). On OS X, I am only
getting a hit on m_pollingscheduler, since sched_useaudio =
SCHED_AUDIO_POLL. Does sched_useaudio ever equal
SCHED_AUDIO_CALLBACK, which would then cause m_callbackscheduler()
to be used instead?
I'm wondering if sched_tick() is ever called from a non-main thread.
Cheers,
Rich
