DXGKDDI_UPDATEOVERLAY callback function

-description

The DxgkDdiUpdateOverlay function modifies the overlay hardware.

-parameters

-param hOverlay [in]

A handle to the overlay to modify. The display miniport driver's DxgkDdiCreateOverlay function previously provided this handle to the Microsoft DirectX graphics kernel subsystem in the hOverlay member of the DXGKARG_CREATEOVERLAY structure that pCreateOverlay points to.

-param pUpdateOverlay [in]

A pointer to a DXGKARG_UPDATEOVERLAY structure that describes how to modify the overlay hardware.

-returns

DxgkDdiUpdateOverlay returns one of the following values:

Return code Description
STATUS_SUCCESS DxgkDdiUpdateOverlay successfully modified the overlay.
STATUS_INVALID_PARAMETER Parameters that were passed to DxgkDdiUpdateOverlay contained errors that prevented it from completing.
STATUS_NO_MEMORY DxgkDdiUpdateOverlay could not allocate memory that was required for it to complete.
STATUS_INSUFFICIENT_RESOURCES DxgkDdiUpdateOverlay could not complete because insufficient bandwidth was available or the requested overlay hardware could not complete the task.
STATUS_GRAPHICS_DRIVER_MISMATCH The display miniport driver is not compatible with the user-mode display driver that initiated the call to DxgkDdiUpdateOverlay.

-remarks

DxgkDdiUpdateOverlay should be made pageable.
