DDHAL_FLIPVPORTDATA

The DDHAL_FLIPVPORTDATA structure contains the information necessary for the video port to perform a flip. This structure passes the information to the DirectDraw HAL FlipVideoPort callback function.

typedef struct _DDHAL_FLIPVPORTDATA
{
LPDDRAWI_DIRECTDRAW_LCL      lpDD;
LPDDRAWI_DDVIDEOPORT_LCL     lpVideoPort;
LPDDRAWI_DDRAWSURFACE_LCL    lpSurfCurr;
LPDDRAWI_DDRAWSURFACE_LCL    lpSurfTarg;
HRESULT                      ddRVal;
LPDDHALVPORTCB_FLIP          FlipVideoPort;
} DDHAL_FLIPVPORTDATA;
