NAME
     audio_engine_set_private, audio_engine_get_private - set  or
     get private state for an audio engine

SYNOPSIS
     #include 

     void *audio_engine_get_private(audio_engine_t *eng);


     void audio_engine_set_private(audio_engine_t *eng, void *state)


PARAMETERS
     eng      pointer  to  an   audio   engine   allocated   with
              audio_engine_alloc(9F)


     state    a private  soft  state  structure  for  the  device
              driver


INTERFACE LEVEL
     Solaris DDI specific (Solaris DDI)

DESCRIPTION
     The audio_engine_set_private() function stores a pointer  to
     the  driver private state for the engine in the audio engine
     structure.


     The  pointer   to   the   private   state   established   by
     audio_engine_set_private()  is  passed as the first argument
     to   the   engine's   entry   points   registered   in   the
     audio_engine_ops(9S) structure.


     The audio_engine_get_private() function retrieves the previ-
     ously stored private state pointer.
