IDirectMusicSegment8::InsertTrack

The InsertTrack method inserts the specified track into the segment's list of tracks.

Syntax

HRESULT InsertTrack(
  IDirectMusicTrack* pTrack,
  DWORD dwGroupBits
);

Parameters

pTrack

Track to add to the segment.

dwGroupBits

Group or groups into which to insert the track. This value cannot be 0.

Return Values

If the method succeeds, the return value is S_OK.

If it fails, the method can return one of the error values shown in the following table.

Return code
DMUS_E_NOT_INIT
E_FAIL
E_INVALIDARG
E_OUTOFMEMORY
E_POINTER

Remarks

Tracks are put in groups to link them correctly. For example, a segment might contain two style tracks and two mute tracks. Each style track would be put in a different group, along with its associated mute track. For more information on track groups, see Identifying the Track.

If the segment is currently playing, the new track is not included in playback because the segment state was not initialized with the new track.

This method initializes the track. However, if the track data is subsequently changed, the application must initialize it again by calling IDirectMusicTrack8::Init.

Requirements
