Audio Library

This chapter describes all of the supported QSA API functions, in alphabetical order; undocumented calls aren't supported.

The QNX Sound Architecture (QSA) has similarities to the Advanced Linux Sound Architecture (ALSA), but isn't compatible. Though the function names may be the same, there's no guarantee that QSA and ALSA calls behave the same (some definitely don't).

For information about the sections in each description, see the What's in a Function Description? chapter of the QNX Neutrino C Library Reference.
