src/lib/libossaudio: ossaudio.c soundcard.h
Adds ioctls and defines for OSSv4 compatibility.
The ioctl definitions and accompanying structures were
taken from FreeBSD's soundcard.h, hopefully providing
some binary compatibility.
The ioctls are as follows:
SNDCTL_SYSINFO: Returns a structure containing
details about the audio device.
SNDCTL_ENGINEINFO - SNDCTL_AUDIOINFO: Returns a
structure with playback/recording
Retrieves/Sets Playback/Recording volume.
SNDCTL_DSP_SKIP - SNDCTL_DSP_SILENCE: These ioctls
were intended to manipulate the underlying
audio buffer skip or insert silence. These
SOUND_VERSION is unchanged, but is definable, It will be
changed when the mixer OSSv4 ioctls are written.
