DD_FLIPVPORTDATA structure (ddrawint.h)

The DD_FLIPVPORTDATA structure contains the information necessary for the video port extensions (VPE) object to perform a flip.

Syntax

typedef struct _DD_FLIPVPORTDATA {
  PDD_DIRECTDRAW_LOCAL lpDD;
  PDD_VIDEOPORT_LOCAL  lpVideoPort;
  PDD_SURFACE_LOCAL    lpSurfCurr;
  PDD_SURFACE_LOCAL    lpSurfTarg;
  HRESULT              ddRVal;
  VOID                 *FlipVideoPort;
} *PDD_FLIPVPORTDATA, DD_FLIPVPORTDATA;

Members

lpDD

Points to a DD_DIRECTDRAW_LOCAL structure that is relevant to the current Microsoft DirectDraw process only.

lpVideoPort

Points to a DD_VIDEOPORT_LOCAL structure that represents this VPE object.

lpSurfCurr

Points to a DD_SURFACE_LOCAL structure for the current surface; that is, the surface on which data is currently being written.

lpSurfTarg

Points to a DD_SURFACE_LOCAL structure for the target surface; that is, the surface to which the driver should flip.

ddRVal

Specifies the location in which the driver writes the return value of the DdVideoPortFlip callback. A return code of DD_OK indicates success. For more information, see Return Values for DirectDraw.

FlipVideoPort

Used by the DirectDraw API and should not be filled in by the driver.
