NtGdiDdUpdateOverlay function

[This function is subject to change with each operating system revision. Instead, use the Microsoft DirectDraw and Microsoft Direct3DAPIs; these APIs insulate applications from such operating system changes, and hide many other difficulties involved in interacting directly with display drivers.]

Repositions or modifies the visual attributes of an overlay surface.

Syntax


DWORD APIENTRY NtGdiDdUpdateOverlay(
  _In_    HANDLE                hSurfaceDestination,
  _In_    HANDLE                hSurfaceSource,
  _Inout_ PDD_UPDATEOVERLAYDATA puUpdateOverlayData
);

Parameters

hSurfaceDestination [in]

Handle to previously created kernel-mode DirectDraw object.

hSurfaceSource [in]

Handle to a DD_SURFACE_LOCAL structure that describes the overlay surface.

puUpdateOverlayData [in, out]

Pointer to a DD_UPDATEOVERLAYDATA structure that contains the information required to update the overlay.

Return value

NtGdiDdUpdateOverlay returns one of the following callback codes.

Return codeDescription
DDHAL_DRIVER_HANDLED

The driver has performed the operation and returned a valid return code for that operation. If this code is DD_OK, DirectDraw or Direct3D proceeds with the function. Otherwise, DirectDraw or Direct3D returns the error code provided by the driver and aborts the function.

DDHAL_DRIVER_NOTHANDLED

The driver has no comment on the requested operation. If the driver is required to have implemented a particular callback, DirectDraw or Direct3D reports an error condition. Otherwise, DirectDraw or Direct3D handles the operation as if the driver callback had not been defined by executing the DirectDraw or Direct3D device-independent implementation.
