NAME

       sndstat - Open Sound System status device

DESCRIPTION

       /dev/sndstat  is  a  text  formatted  device  special file that returns
       information about available (OSS) sound devices. This  device  file  is
       obsolete and the ossinfo(1) utility should be used instead.

       Notice  that  the  device numbering used in this file is different that
       the official numbering used by ossinfo(1)  and  some  other  utilities.
       /dev/sndstat  uses  device  numbers  that match the "legacy" /dev/dspN,
       /dev/midiN and /dev/mixerN device files.

       Application programs should not use /dev/sndstat to obtain  information
       about  the  sound  devices.  The  format of this file may change in the
       future and /dev/sndstat may even be removed from OSS in distant future.
       OSS  4.0  and  later  has  an  ioctl interface for getting detailed and
       reliable information about the devices.

AUDIO USAGE HISTORY

       /dev/sndstat reports some  history  information  about  previously  run
       audio  applications.  This  section  is a debugging aid for application
       developers and it will be moved to the ossinfo program in the future.

       For example:

               History:
               /dev/oss/hdaudio0/pcm0.10: pid 6326 cmd 'error_test' OUT Play events:01009:2 Rec events:01002:0
               /dev/oss/hdaudio0/pcm0.10: pid 6329 cmd 'mpg123' OUT
               /dev/oss/hdaudio0/pcm0.10: pid 6329 cmd 'mpg123' OUT
               /dev/oss/hdaudio0/pcm0.10: pid 6329 cmd 'mpg123' OUT

       Each line  will  show  the  the  device  name,  PID  and  name  of  the
       application  (if known) and access mode (IN and/or OUT). There may also
       be additional info about buffer underruns/overruns and other  recording
       and playback related events.

       Each  Play  and  rec  events  consist  of  5-6  digit  event code and a
       parameter separated by a colon. A list of defined event codes and their
       explanations            can           be           found           from
       http://manuals.opensound.com/developer/oss_error_codes.html.    Purpose
       of  these  events  is  to  inform  application  developers by potential
       problems in their code.

COMPATIBILITY

       /dev/sndstat has been available in all OSS versions. However in OSS 4.0
       and  later this device file should only be used by applications written
       for earlier OSS versions.

OPTIONS

       None

PROGRAMMING INFORMATION

       Some applications use /dev/sndstat to find the audio devices  available
       in  the  system.  This  method  is  no longer recommended. Applications
       should use the SNDCTL_AUDIOINFO(2) ioctl call to find the devices.
