If the function fails, the return value may be one of the following error values:
- DDERR_INVALIDPARAMS
- DDERR_OUTOFMEMORY
- CLASS_E_NOAGGREGATION
Remarks
This function can be called before any DirectDraw objects are created.
Because these DirectDrawClipper objects are not owned by any DirectDraw object, they are not released when an application's objects are released. If the application does not explicitly release the DirectDrawClipper objects, DirectDraw releases them when the application terminates.
To create a DirectDrawClipper object owned by a specific DirectDraw object, use the IDirectDraw::CreateClipper method.
