DD_SURFACE_LOCAL structure (ddrawint.h)

The DD_SURFACE_LOCAL structure contains surface-related data that is unique to an individual surface object.

Syntax

typedef struct _DD_SURFACE_LOCAL {
  PDD_SURFACE_GLOBAL lpGbl;
  DWORD              dwFlags;
  DDSCAPS            ddsCaps;

    DDCOLORKEY ddckCKSrcBlt;
  };
  union {
    DDCOLORKEY ddckCKDestOverlay;
    DDCOLORKEY ddckCKDestBlt;
  };
  PDD_SURFACE_MORE   lpSurfMore;
  PDD_ATTACHLIST     lpAttachList;
  PDD_ATTACHLIST     lpAttachListFrom;
  RECT               rcOverlaySrc;
} *PDD_SURFACE_LOCAL, DD_SURFACE_LOCAL;

Members

lpGbl

Points to the DD_SURFACE_GLOBAL structure containing surface data that is shared globally with multiple surfaces.

dwFlags

Specifies a set of surface flags. This member is a bitwise OR of any of the following values:

Flag	Meaning
DDRAWISURF_BACKBUFFER	The surface was originally a back buffer.
DDRAWISURF_DRIVERMANAGED	The surface is a driver managed texture used with Microsoft Direct3D.
DDRAWISURF_FRONTBUFFER	The surface was originally a front buffer.
DDRAWISURF_HASCKEYSRCBLT	The surface has source color key overlay data in the ddckCKSrcBlt member.
DDRAWISURF_HASOVERLAYDATA	The surface has overlay data.
DDRAWISURF_HASPIXELFORMAT	The surface has pixel format data.
DDRAWISURF_INVALID	The surface has been invalidated by a mode setting operation.

ddsCaps

Specifies a DDSCAPS structure that describes the capabilities of the surface.

dwReserved1

Reserved for use by the display driver.

ddckCKSrcOverlay

Specifies a DDCOLORKEY structure (defined in the Microsoft DirectDraw SDK documentation) that contains the color key information for source overlay use.

ddckCKSrcBlt

Specifies a DDCOLORKEY structure that describes the color key for source color key overlays.

ddckCKDestOverlay

Specifies a DDCOLORKEY structure that contains the color key information for destination overlay use.

ddckCKDestBlt

Specifies a DDCOLORKEY structure that describes the color key for destination color key overlays.

lpSurfMore

Points to a DD_SURFACE_MORE structure that contains additional local surface data.

lpAttachList

Points to a DD_ATTACHLIST structure that contains the list of surfaces to which this surface attached.

lpAttachListFrom

Points to a DD_ATTACHLIST structure that contains the list of surfaces attached to this surface.

rcOverlaySrc

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