CVSROOT: /cvs
Module name: src
Changes by: jakemsrcvs.openbsd.org 2007/10/03 15:49:13

Modified files:
        share/man/man4 : audio.4
        sys/sys : audioio.h
        sys/dev : audio.c
        regress/sys/dev/audio_rw: Makefile audiotest_rw.1 audiotest_rw.c

Log message:
add two new audio ioctls, AUDIO_GETPRINFO and AUDIO_GETRRINFO, and the
data structure these ioctls use, audio_bufinfo.

these ioctls return information about the play and record buffers
into the audio_bufinfo structure.

these are being added to aid in porting non-native audio applications
and libraries, and to fix issues in our OSS audio emulation. these
ioctls exist only on OpenBSD and should not be used in code intended
for distribution.
