ossaudio

OSSAUDIO(3)						   BSD Library Functions Manual 					       OSSAUDIO(3)

NAME

     ossaudio -- OSS audio emulation

LIBRARY

     OSS Audio Emulation Library (libossaudio, -lossaudio)

SYNOPSIS

     #include <soundcard.h>

DESCRIPTION

     The ossaudio library provides an emulation of the OSS (Linux) audio interface.

     Use the native interface for new programs and the emulation library only for porting programs.

   Mixer Control Map
     The following table summarizes the mappings from native interface device names to OSS mixer controls.

     Native Device Name    OSS Mixer Control
     *.mic		   SOUND_MIXER_MIC
     *.line		   SOUND_MIXER_LINE
     *.cd		   SOUND_MIXER_CD
     *.dac		   SOUND_MIXER_PCM
     *.aux		   SOUND_MIXER_LINE1
     *.record		   SOUND_MIXER_IMIX
     *.master		   SOUND_MIXER_VOLUME
     *.treble		   SOUND_MIXER_TREBLE
     *.bass		   SOUND_MIXER_BASS
     *.speaker		   SOUND_MIXER_SPEAKER
     *.output		   SOUND_MIXER_OGAIN
     *.input		   SOUND_MIXER_IGAIN
     *.fmsynth		   SOUND_MIXER_SYNTH
     *.midi		   SOUND_MIXER_SYNTH

SEE ALSO

     audio(4), midi(4)

HISTORY

     The ossaudio library first appeared in NetBSD 1.3.

BUGS

     The emulation uses a #define for ioctl() so some obscure programs can fail to compile.

     The emulation is incomplete.

     The emulation only covers ioctl(), there are other differences as well.  E.g., on a write that would block in non-blocking mode Linux returns
     EINTR whereas NetBSD 1.3 returns EAGAIN.
