The D3DDDIARG_CREATEOVERLAY structure describes an overlay to create.
Syntax
typedef struct _D3DDDIARG_CREATEOVERLAY {
[in] D3DDDI_VIDEO_PRESENT_SOURCE_ID VidPnSourceId;
[in] D3DDDI_OVERLAYINFO OverlayInfo;
[out] HANDLE hOverlay;
} D3DDDIARG_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 pointer to the D3DDDI_OVERLAYINFO structure that describes information about the overlay.
[out] hOverlay
