D3DDDICB_CREATEOVERLAY structure (d3dumddi.h)

  • Article

The D3DDDICB_CREATEOVERLAY structure describes overlay hardware.

Syntax

typedef struct _D3DDDICB_CREATEOVERLAY {
  [in]  D3DDDI_VIDEO_PRESENT_SOURCE_ID VidPnSourceId;
  [in]  D3DDDI_KERNELOVERLAYINFO       OverlayInfo;
  [out] D3DKMT_HANDLE                  hKernelOverlay;
} D3DDDICB_CREATEOVERLAY;

Members

[in] VidPnSourceId

The zero-based identification number of the video present source in a path of a video present network (VidPN) topology to overlay on (that is, the identifier of the primary surface to overlay on).

[in] OverlayInfo

A D3DDDI_KERNELOVERLAYINFO structure that describes information about the kernel-mode overlay object.

[out] hKernelOverlay

A D3DKMT_HANDLE data type that represents a kernel-mode handle to the kernel-mode overlay object. This overlay object represents the overlay hardware in subsequent calls by the user-mode display driver to the Microsoft Direct3D runtime.
