  • Article

The DD_GETBLTSTATUSDATA structure returns the blit status information.

Syntax

typedef struct _DD_GETBLTSTATUSDATA {
  PDD_DIRECTDRAW_GLOBAL lpDD;
  PDD_SURFACE_LOCAL     lpDDSurface;
  DWORD                 dwFlags;
  HRESULT               ddRVal;
  VOID                  *GetBltStatus;
} *PDD_GETBLTSTATUSDATA, DD_GETBLTSTATUSDATA;

Members

lpDD

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

lpDDSurface

Points to a DD_SURFACE_LOCAL structure representing the surface whose blit status is being queried.

dwFlags

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

Flag Meaning
DDGBS_CANBLT Queries whether the driver can currently perform a blit.
DDGBS_ISBLTDONE Queries whether the driver has completed the last blit.

ddRVal

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