IDirectMusicPerformance::MusicToReferenceTime

The IDirectMusicPerformance::MusicToReferenceTime method converts time in MUSIC_TIME format to time in REFERENCE_TIME format.

HRESULT MusicToReferenceTime(
  MUSIC_TIME mtTime,
  REFERENCE_TIME* prtTime
);

Parameters

mtTime
The time in MUSIC_TIME format to convert.
prtTime
Address of a variable to receive the converted time in REFERENCE_TIME format.

Return Values

If the method succeeds, the return value is S_OK.

If it fails, the method may return one of the following error values:

E_POINTER
DMUS_E_NO_MASTER_CLOCK

Remarks

Because reference time has a greater precision than music time, a time that has been converted from reference time to music time, and then back again, will likely not have its original value.
