PFNDDXGIDDI_PRESENT_MULTIPLANE_OVERLAYCB callback function (dxgiddi.h)

PFNDDXGIDDI_PRESENT_MULTIPLANE_OVERLAYCB is called by the DirectX Graphics Infrastructure (DXGI) runtime to notify the user-mode display driver that an application finished rendering and requests that the driver display the source surface by either copying or flipping or that the driver perform a color-fill operation. Must be implemented by Windows Display Driver Model (WDDM) 1.3 or later drivers that support multiplane overlays.

Syntax

PFNDDXGIDDI_PRESENT_MULTIPLANE_OVERLAYCB PfnddxgiddiPresentMultiplaneOverlaycb;

HRESULT PfnddxgiddiPresentMultiplaneOverlaycb(
  HANDLE hDevice,
  const DXGIDDICB_PRESENT_MULTIPLANE_OVERLAY *unnamedParam2
)
{...}

Parameters

hDevice

A handle to a display device (graphics context).

unnamedParam2

pPresentDXGI is a pointer to a DXGI_DDI_ARG_PRESENTMULTIPLANEOVERLAY structure that describes how to display to the destination surface.

Return value

If this callback function succeeds, it returns S_OK. Otherwise, it returns an HRESULT error code.

Remarks

When the user-mode display driver successfully completes its processing of a call to this function, it presents the source surface to the display by calling the pfnPresentMultiPlaneOverlayCb (DXGI) function.
