Ah thanks for pointing that out, Hans.
m_callbackscheduler() is soooo much more simple than m_pollingscheduler(), I'm wondering what the performance differences are..
Cheers, Rich

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.
