The SetLoopPoints method sets the start and end points of the part of the segment that repeats the number of times set by the IDirectMusicSegment8::SetRepeats method.
Syntax
HRESULT SetLoopPoints(
MUSIC_TIME mtStart,
MUSIC_TIME mtEnd
);
Parameters
mtStart
Point at which to begin the loop.
mtEnd
Point at which to end the loop. A value of 0 loops the entire segment.
Return Values
If the method succeeds, the return value is S_OK.
If it fails, the method can return DMUS_E_OUT_OF_RANGE.
Remarks
When the segment is played, it plays from the segment start time until mtEnd, then loops to mtStart, plays the looped portion the number of times set by IDirectMusicSegment8::SetRepeats, and then plays to the end.
The default values are set to loop the entire segment from beginning to end.
The method fails if mtStart is greater than or equal to the length of the segment, or if mtEnd is greater than the length of the segment. If mtEnd is 0, mtStart must be 0 as well.
This method does not affect any currently playing segment states created from this segment.
The loop points of a cached segment persist even if the segment is released, and then reloaded. To ensure that a segment is not subsequently reloaded from the cache, call IDirectMusicLoader8::ReleaseObject on it before releasing it.
