GetBackground method
Retrieves a pointer to the DXSurface used as a background.
Syntax
HRESULT retVal = object.GetBackground(ppSurface);
Parameters
ppSurface [out]
Type: IDXSurfaceAddress of a pointer to the interface through which to access the background surface.
Remarks
If there is currently no background surface, this method returns S_OK, but ppSurface is set to NULL. When the method is implemented, it automatically calls AddRef on the interface. The client is responsible for calling Release on the interface when it is no longer needed.
