By the way, why not using AUDeferredRenderer and let it manage all this theading/sync nightmare?  It looks design exactly for what you're trying to achieve (AFAIU).

To whom it may concern:

I’ve started working on using TPCircularBuffer to manage the output of a music playback library (libxmp: http://xmp.sourceforge.net/libxmp.html), but I’m stumped on the best way to manage overruns.

Currently, my code does take the audio data into the buffer and render it out on the rendering callback, but there doesn’t seem to be a way to check if the buffer is full with a TPCircularBuffer before pushing data into the buffer.

What should I be doing in my code to make it work?

(I was able to send equal-size chunks of audio from the library in my rendering callback without issue, but the ring buffer will work better for the app I want to build.)

Thanks in advance for any help!

—Douglas
