The D3DDDICB_CREATEOVERLAY structure describes overlay hardware.

Syntax


typedef struct _D3DDDICB_CREATEOVERLAY {
  D3DDDI_VIDEO_PRESENT_SOURCE_ID VidPnSourceId;
  D3DDDI_KERNELOVERLAYINFO       OverlayInfo;
  D3DKMT_HANDLE                  hKernelOverlay;
} D3DDDICB_CREATEOVERLAY;

Members

VidPnSourceId

[in] 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).

OverlayInfo

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

hKernelOverlay

[out] 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.

Requirements

Version
