Solaris DDI specific (Solaris DDI)
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 previously stored private state pointer.
The audio_engine_get_private() function returns the device driver private state pointer.
These functions may be called from any context.
