This method retrieves the clipping list.
Syntax
HRESULT GetClipList(
RECT* pSourceRect,
RECT* pDestinationRect,
RGNDATA** ppRgnData
);
Parameters
- pSourceRect
[out] A pointer to a RECT structure that describes the bounding client rectangle.
- pDestinationRect
[in] A pointer to a RECT structure that describes the destination rectangle.
- ppRgnData
[out] A pointer to a RGNDATA pointer that contains the header and data that describes clipping. If successful, the Win32 CoTaskMemFree function should free memory.
Return Value
None.
Remarks
The IOverlay implementation allocates the memory for the clipping rectangles, because it can vary in length. The filter calling this method should free the memory (using CoTaskMemFree) when it is finished with it.
