Kernel Functions for Drivers                   audio_init_ops(9F)



NAME
     audio_init_ops, audio_fini_ops - initialize DDI entry points
     for an audio device driver

SYNOPSIS
     #include 

     void audio_init_ops(struct dev_ops *devops, const char *name);


     void audio_fini_ops(struct dev_ops *devops);


PARAMETERS
     devops    pointer to the dev_ops(9S) vector for  the  device
               instance


     name      name of the audio driver, which must be  the  same
               as the kernel module name. For example, "audiohd".


INTERFACE LEVEL
     Solaris DDI specific (Solaris DDI)

DESCRIPTION
     The audio_init_ops() function initializes the device  opera-
     tions  vector for an audio driver, setting a number of entry
     points to common implementation from the audio framework. It
     must  be  executed  during  the  _init(9E)  function for the
     driver.


     The actual  values  supplied  by  audio_init_ops()  are  the
     fields for devo_cb_ops and devo_getinfo.


     Device drivers need to supply any other entry points,  espe-
     cially  the  attach(9E),  detach(9E),  and quiesce(9E) entry
     points.


     The ddi_driver_name(9F) function cannot be used to determine
     the  device  driver's  name,  as  there is not necessarily a
     dev_info_t to use during the _init(9E) entry point.  A  con-
     stant string must be supplied by the driver.


     The   audio_fini_ops()   function   undoes   the   work   of
     audio_init_ops()   and   releases   resources  allocated  by
     audio_init_ops().

Kernel Functions for Drivers                   audio_init_ops(9F)



CONTEXT
     These functions may be called from  the  driver's  _init(9E)
     and _fini(9E) entry points only.

     Writing Device Drivers

NOTES
     Audio device driver names are limited to at most 12  charac-
     ters.


     The audio DDI is provided by the drv/audio module.  Develop-
     ers  should  supply "-dy -Ndrv/audio" on the final link com-
     mand line to ensure that symbol dependencies can  be  satis-
     fied when the driver is loaded.
