HRESULT GetSurface( REFIID riid, void **ppSurface );

- [out] Address of a pointer to the requested interface.

This method retrieves a pointer to the parent surface associated with the specified IDXARGBReadPtr interface. It provides a link between the IDXSurface::LockSurface interface, which exposes the IDXARGBReadPtr and IDXARGBReadWritePtr interfaces, and the DXSurface object, which exposes the IDXSurface interface.
