alGetEventUST(3dm)                                          alGetEventUST(3dm)



NAME
     alGetEventUST - get Unadjusted System Time of audio event

SYNOPSIS
     #include <dmedia/audio.h>

     long long alGetEventUST(ALevent event)


PARAMETER
     event   expects an ALevent structure initialized by alNextEvent(3dm) or
             alCheckEvent(3dm).

DESCRIPTION
     alGetEventUST returns the Unadjusted System Time (UST) from the ALevent
     structure.

     The UST is a 64-bit number in nanoseconds indicating when the event was
     posted. It lies on the same timeline as the time returned by
     alGetFrameTime(3dm).


DIAGNOSTICS
     Upon successful completion, alGetEventUST returns a long long whose value
     is the Unadjusted System Time (UST) for the audio event.  Otherwise,
     alGetEventUST returns -1 and sets an error number. This error number can
     be retrieved with oserror(3C).

     alGetEventUST can fail for the following reason:

     ALBADINVALIDEVENT   event is invalid or null.
