Microsoft DirectX 9.0


The SplitAt method splits the object at the specified time.





Time at which to split the object, relative to the start of the timeline, in 100-nanosecond units.

Return Value

Returns an HRESULT value. Possible values include the following:

Value Description
S_FALSE Nothing to split.
S_OK Success.
E_INVALIDARG The object does not exist at this time.
E_OUTOFMEMORY Insufficient memory.


If you split a source, effect, or transition, this method creates a second object of the same type. The original object is truncated at the specified split time, and the new object replaces the truncated portion. The new object inherits all of the same properties. In a source object, the method also splits any effects that fall on the split time.

Calling this method on a track splits all the sources, effects, and transitions that are contained in the track at the specified split time. It does not create a second track. (A track begins at time zero and extends to infinity.)

For a track, if the split time is later than everything in the track, the method returns S_FALSE. For any other object, if the split time does not fall anywhere within the object, the method returns E_INVALIDARG.
