The DD_GETFLIPSTATUSDATA structure returns the flip status information.

Syntax

typedef struct _DD_GETFLIPSTATUSDATA {
  PDD_DIRECTDRAW_GLOBAL lpDD;
  PDD_SURFACE_LOCAL     lpDDSurface;
  DWORD                 dwFlags;
  HRESULT               ddRVal;
  VOID                  *GetFlipStatus;
} *PDD_GETFLIPSTATUSDATA, DD_GETFLIPSTATUSDATA;

Members

lpDD

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

lpDDSurface

Points to a DD_SURFACE_LOCAL structure that describes the surface whose flip status is being queried.

dwFlags

Specifies the flip status being requested. This member can be one of the following values:

Flag Meaning
DDGFS_CANFLIP Queries whether the driver can currently perform a flip.
DDGFS_ISFLIPDONE Queries whether the driver has finished the last flip.

ddRVal

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