D3DDDICB_CREATEOVERLAY structure (d3dumddi.h)
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.
