DD_PALETTECALLBACKS structure (ddrawint.h)
The DD_PALETTECALLBACKS structure contains entry pointers to the DirectDraw palette callback functions that a device driver supports.
Syntax
typedef struct DD_PALETTECALLBACKS {
DWORD dwSize;
DWORD dwFlags;
PDD_PALCB_DESTROYPALETTE DestroyPalette;
PDD_PALCB_SETENTRIES SetEntries;
} DD_PALETTECALLBACKS;
Members
dwSize
Specifies the size in bytes of this DD_PALETTECALLBACKS structure.
dwFlags
Indicates what DirectDrawPalette 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_PALCB32_DESTROYPALETTE
- DDHAL_PALCB32_SETENTRIES
DestroyPalette
Points to the driver-supplied DdDestroyPalette palette callback.
SetEntries
Points to the driver-supplied DdSetEntries palette callback.
Remarks
Entries that the display driver does not use should be set to NULL. The driver initializes this structure in DrvEnableDirectDraw.
