Description

The DxgkDdiCreateOverlay function enables the overlay hardware if the hardware is capable.

Parameters

hAdapter [in]

pCreateOverlay [in/out]

A pointer to a DXGKARG_CREATEOVERLAY structure that describes the overlay.

Return value

DxgkDdiCreateOverlay returns one of the following values:

Return code Description
STATUS_SUCCESS DxgkDdiCreateOverlay successfully created the overlay.
STATUS_INVALID_PARAMETER Parameters that were passed to DxgkDdiCreateOverlay contained errors that prevented it from completing.
STATUS_NO_MEMORY DxgkDdiCreateOverlay could not allocate memory that was required for it to complete.
STATUS_INSUFFICIENT_RESOURCES DxgkDdiCreateOverlay 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 DxgkDdiCreateOverlay.
