The DD_SURFACECALLBACKS structure contains pointers to the DirectDraw surface callbacks that a device driver supports. The driver initializes this structure in DrvEnableDirectDraw.

Members

dwSize

Size, in bytes, of the DD_SURFACECALLBACKS structure. This field is unused by Windows NT.

dwFlags

Bitmask that the driver initializes to indicate which DirectDraw surface callbacks it supports. For every bit set in dwFlags, the driver must initialize the corresponding function pointer member of this structure. Bitfields are enumerated in ddrawint.h as DDHAL_SURFCB32_Xxx.

DestroySurface

Pointer to the driver-supplied DestroySurface surface callback.

Flip

Pointer to the driver-supplied Flip surface callback.

SetClipList

Pointer to the driver-supplied SetClipList surface callback.

Lock

Pointer to the driver-supplied Lock surface callback.

Unlock

Pointer to the driver-supplied Unlock surface callback.

Blt

Pointer to the driver-supplied Blt surface callback.

SetColorKey

Pointer to the driver-supplied SetColorKey surface callback.

AddAttachedSurface

Pointer to the driver-supplied AddAttachedSurface surface callback.

GetBltStatus

Pointer to the driver-supplied GetBltStatus surface callback.

GetFlipStatus

Pointer to the driver-supplied GetFlipStatus surface callback.

UpdateOverlay

Pointer to the driver-supplied UpdateOverlay surface callback.

SetOverlayPosition

Pointer to the driver-supplied SetOverlayPosition surface callback.

reserved4

Reserved for system use.

SetPalette

Pointer to the driver-supplied SetPalette surface callback.
