DD_SURFACECALLBACKS structure (ddrawint.h)

The DD_SURFACECALLBACKS structure contains entry pointers to the Microsoft DirectDraw surface callback functions that a device driver supports.

Syntax

typedef struct DD_SURFACECALLBACKS {
  DWORD                         dwSize;
  DWORD                         dwFlags;

  PDD_SURFCB_FLIP               Flip;
  PDD_SURFCB_SETCLIPLIST        SetClipList;
  PDD_SURFCB_LOCK               Lock;
  PDD_SURFCB_UNLOCK             Unlock;
  PDD_SURFCB_BLT                Blt;
  PDD_SURFCB_SETCOLORKEY        SetColorKey;

} DD_SURFACECALLBACKS;

Members

dwSize

Specifies the size in bytes of the DD_SURFACECALLBACKS structure. This member is unused by Microsoft Windows 2000 and later versions.

dwFlags

Indicates which DirectDrawSurface callback functions the driver has implemented. For every bit set in dwFlags, the driver must initialize the corresponding function pointer member of this structure. This member can be one or more of the following flags:

DDHAL_SURFCB32_DESTROYSURFACE

DDHAL_SURFCB32_FLIP

DDHAL_SURFCB32_SETCLIPLIST

DDHAL_SURFCB32_LOCK

DDHAL_SURFCB32_UNLOCK

DDHAL_SURFCB32_BLT

DDHAL_SURFCB32_SETCOLORKEY

DDHAL_SURFCB32_ADDATTACHEDSURFACE

DDHAL_SURFCB32_GETBLTSTATUS

DDHAL_SURFCB32_GETFLIPSTATUS

DDHAL_SURFCB32_UPDATEOVERLAY

DDHAL_SURFCB32_SETOVERLAYPOSITION

DDHAL_SURFCB32_SETPALETTE

DestroySurface

Points to the driver-supplied DdDestroySurface surface callback.

Flip

Points to the driver-supplied DdFlip surface callback.

SetClipList

Points to the driver-supplied DdSetClipList surface callback.

Lock

Points to the driver-supplied DdLock surface callback.

Unlock

Points to the driver-supplied DdUnlock surface callback.

Blt

Points to the driver-supplied DdBlt surface callback.

SetColorKey

Points to the driver-supplied DdSetColorKey surface callback.

AddAttachedSurface

Points to the driver-supplied DdAddAttachedSurface surface callback.

GetBltStatus

Points to the driver-supplied DdGetBltStatus surface callback.

GetFlipStatus

Points to the driver-supplied DdGetFlipStatus surface callback.

UpdateOverlay

Points to the driver-supplied DdUpdateOverlay surface callback.

SetOverlayPosition

Points to the driver-supplied DdSetOverlayPosition surface callback.

reserved4

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

SetPalette

Points to the driver-supplied DdSetPalette surface callback.

Remarks

Entries that the display driver does not use should be set to NULL. The driver initializes this structure in DrvEnableDirectDraw.
