The DD_FLIPTOGDISURFACEDATA structure contains the GDI surface notification information.

Syntax

typedef struct _DD_FLIPTOGDISURFACEDATA {
  PDD_DIRECTDRAW_GLOBAL lpDD;
  DWORD                 dwToGDI;
  DWORD                 dwReserved;
  HRESULT               ddRVal;
  VOID                  *FlipToGDISurface;
} *PDD_FLIPTOGDISURFACEDATA, DD_FLIPTOGDISURFACEDATA;

Members

lpDD

Points to the DD_DIRECTDRAW_GLOBAL structure that describes the driver's device.

dwToGDI

Indicates that Microsoft DirectDraw is flipping to a GDI surface when TRUE; indicates that DirectDraw is flipping from a GDI surface when FALSE.

dwReserved

Reserved for system use and should be ignored by the driver.

ddRVal

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

FlipToGDISurface
