  • Article

The D3DKMT_WAITFORVERTICALBLANKEVENT structure describes parameters for waiting for the vertical blanking interval to occur.

Syntax

typedef struct _D3DKMT_WAITFORVERTICALBLANKEVENT {
  [in] D3DKMT_HANDLE                  hAdapter;
  [in] D3DKMT_HANDLE                  hDevice;
  [in] D3DDDI_VIDEO_PRESENT_SOURCE_ID VidPnSourceId;
} D3DKMT_WAITFORVERTICALBLANKEVENT;

Members

[in] hAdapter
