DWORD dwFlags,
LPDIRECTDRAWCLIPPER FAR* lplpDDClipper,
IUnknown FAR* pUnkOuter
);
Parameters
- dwFlags
[in] Currently not used; set to zero.
- lplpDDClipper
[out] Address of a pointer that will be filled with the address of the new DirectDrawClipper object.
pUnkOuter
[in] Allows for future compatibility with COM aggregation functionality.This method returns CLASS_E_NOAGGREGATION if this parameter is anything but NULL.
Return Value
If the function succeeds, the return value is DD_OK.
If the function fails, the return value may be one of the following error values:
- DirectDraw Return Values
- DirectDraw Return Values
- 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.
