The DDNONLOCALVIDMEMCAPSstructure contains the capabilities for non-local display memory.
typedef struct _DDNONLOCALVIDMEMCAPS { DWORD
dwSize
;
DWORD
dwNLVBCaps
;
DWORD
dwNLVBCaps2
;
DWORD
dwNLVBCKeyCaps
;
DWORD
dwNLVBFXCaps
;
DWORD
dwNLVBRops[DD_ROP_SPACE]
;
} DDNONLOCALVIDMEMCAPS;
typedef struct _DDNONLOCALVIDMEMCAPS FAR
*LPDDNONLOCALVIDMEMCAPS;
Members
- dwSize
- Size of the structure. This member must be initialized before the structure is used.
- dwNLVBCaps
- Contains the driver-specific capabilities for non-local to local display memory blits.
- dwNLVBCaps2
- Contains more of the driver-specific capabilities for non-local to local display memory blits.
- dwNLVBCKeyCaps
- Contains driver color key capabilities for non-local to local display memory blits.
- dwNLVBFXCaps
- Contains driver FX capabilities for non-local to local display memory blits.
- dwNLVBRops[DD_ROP_SPACE]
- Contains the raster operations supported for non-local to local
blits.
Remarks
Normally, the dwNLVBCaps, dwNLVBCaps2, dwNFLBCKeyCaps, dwNLVBFXCaps, and dwNLVBRopsmembers contain a subset of the flags used in the DDCORECAPSstructure that is relevant to non-local to local blitting. However, to allow flexibility for device driver writers, any of the flags in DDCORECAPScan be used.
