NAME
     audio_engine_start, audio_engine_stop -  start  or  stop  an
     audio engine

SYNOPSIS
     #include 

     int prefix_start(void *state);


     void prefix_stop(void *state);


PARAMETERS
     state    pointer to driver supplied soft state


INTERFACE LEVEL
     Solaris DDI specific (Solaris DDI)

DESCRIPTION
     The audio_engine_start() function  starts  an  audio  engine
     that  has  been initialized with audio_engine_open(9E). This
     initiates actual playback or recording of  audio.  The  data
     transfer  must  start  at  the  first  frame in the engine's
     buffer.


     The audio_engine_stop() function stops an audio engine  that
     was  previously started with audio_engine_start() and resets
     the frame index back to 0. The master frame counter for  the
     engine is not reset.


     Once audio_engine_stop() returns, the engine must  not  per-
     form any further data transfers to or from the audio buffer.
     Furthermore, actual play back or capture of audio associated
     with the engine shall have ceased.

RETURN VALUES
     The audio_engine_start() function returns 0 on success or an
     error number on failure.

CONTEXT
     These functions may be called from user, kernel,  or  inter-
     rupt context.
