Interrupt-driven (or callback/handler?), Full-duplex (simultaneous capture/playback) without using JACK

["Ryan Cassidy" <rcassidy@stanford.edu>]

Hi all,

I am trying to write an application that uses ALSA interrupt-driven
(which I guess is obtained by adding PCM handler(s) in ALSA?),
full-duplex (simultaneous capture/playback) using the ALSA PCM API
directly (i.e. not using JACK).

My question: do I only need to register one callback/handler function to
take care of both capture and playback?  My hope is that when I link the
capture and playback streams, and register a single handler with either
capture or playback, this handler will be called whenever there is BOTH
capture data to be read and a free playback buffer to be written (?).
Is this the case?

Any help, info., or advice GREATLY appreciated.

Cheers, rjc.
