D3DKMT_OPENADAPTERFROMHDC structure (d3dkmthk.h)

  • Artikel

The D3DKMT_OPENADAPTERFROMHDC structure describes the mapping of a device context handle (HDC) to a graphics adapter handle and monitor output.

Syntax

typedef struct _D3DKMT_OPENADAPTERFROMHDC {
  [in]  HDC                            hDc;
  [out] D3DKMT_HANDLE                  hAdapter;
  [out] LUID                           AdapterLuid;
  [out] D3DDDI_VIDEO_PRESENT_SOURCE_ID VidPnSourceId;
} D3DKMT_OPENADAPTERFROMHDC;

Members

[in] hDc

The HDC for the graphics adapter and monitor output that are retrieved.

[out] hAdapter

A handle to the graphics adapter for the HDC that hDc specifies. The adapter handle is returned from the call to the D3DKMTOpenAdapterFromHdc function.

[out] AdapterLuid

The locally unique identifier (LUID) of the graphics adapter for the HDC that hDc specifies. The LUID is returned from the D3DKMTOpenAdapterFromHdc call.

[out] VidPnSourceId

The zero-based identification number of the video present source in a path of a video present network (VidPN) topology for the HDC that hDc specifies. The identification number is returned from the D3DKMTOpenAdapterFromHdc call.
