IDirectMusicPerformance::AdjustTime

The IDirectMusicPerformance::AdjustTime method adjusts the internal performance time forward or backward. This is mostly used to compensate for drift when synchronizing to another source.

HRESULT AdjustTime(
  REFERENCE_TIME rtAmount
);
 

Parameters

rtAmount

The amount of time to add or subtract. This may be a number from –10,000,000 to 10,000,000 (–1 second to +1 second).

Return Values

If the method succeeds, the return value is S_OK.

If it fails, the method may return E_INVALIDARG.

Remarks

The adjusted time is used internally by DirectMusic. It is not reflected in the time retrieved by the IDirectMusicPerformance::GetTime method.
