NAME
     audio_dev_add_engine,  audio_dev_remove_engine  -   add   or
     remove an audio engine to or from a device

SYNOPSIS
     #include 

     void audio_dev_add_engine(audio_dev_t *adev, audio_engine_t *engine);


     void audio_dev_remove_engine(audio_dev_t *adev, audio_engine_t *engine);


PARAMETERS
     adev      pointer  to  an  audio   device   allocated   with
               audio_dev_alloc(9F)


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


INTERFACE LEVEL
     Solaris DDI specific (Solaris DDI)

DESCRIPTION
     The audio_dev_add_engine() function associates an  allocated
     and initialized engine with an audio device.


     Multiple engines may be added to an  audio  device  in  this
     fashion. Usually device drivers perform this at least twice:
     once for a playback engine and once  for  a  record  engine.
     Multiple playback engines can be especially useful in allow-
     ing the framework to avoid software mixing  overhead  or  to
     support engines running with different parameters. For exam-
     ple, different engines may support different  audio  formats
     or different sample rates.


     Generally, audio_dev_add_engine() should  be  called  before
     registering  the audio device with the audio framework using
     audio_dev_register(9F).


     The audio_dev_remove_engine()  function  removes  an  engine
     from  the  list of engines associated with a device. This is
     generally called during detach(9E) processing.

CONTEXT
     These functions may be called from user  or  kernel  context
     only.
