The StopEx method stops playback of a segment, segment state, or audiopath.
Syntax
HRESULT StopEx(
IUnknown *pObjectToStop,
__int64 i64StopTime,
DWORD dwFlags
);
Parameters
pObjectToStop
Pointer to the IUnknown interface of the segment, segment state, or audiopath to stop.
i64StopTime
Time at which to stop. If the time is in the past or if 0 is passed in this parameter, the object stops playing immediately.
dwFlags
Flags that adjust the time when the stop should occur. Boundaries are in relation to the current primary segment. Can be 0 or one of the following values. DMUS_SEGF_REFTIME can be combined with one other flag.
| Value | Description |
| DMUS_SEGF_AUTOTRANSITION | Not implemented. |
| DMUS_SEGF_BEAT | Stop on the next beat boundary at or after i64StopTime. |
| DMUS_SEGF_DEFAULT | Stop on the default boundary, as set by the IDirectMusicSegment8::SetDefaultResolution method. |
| DMUS_SEGF_GRID | Stop on the next grid boundary at or after i64StopTime. |
| DMUS_SEGF_MEASURE | Stop on the next measure boundary at or after i64StopTime. |
| DMUS_SEGF_REFTIME | The value in i64StopTime is in reference time. |
| DMUS_SEGF_SEGMENTEND | Stop at the end of the primary segment. |
| DMUS_SEGF_MARKER | Stop at the next marker. |
Return Values
If the method succeeds, the return value is S_OK.
If it fails, the method can return E_POINTER.
Remarks
Stopping a segment stops all instances that are playing. Stopping an audiopath stops all segments playing on that audiopath.
