This section shows the definition of the DDGPEAllocSurfaceData structure.
Syntax
#define DDGPEALLOCSURFACEDATA_VERSION0(0)
#define DDGPEALLOCSURFACEDATA_CURRENTVERSION
(DDGPEBLTPARMS_VERSION0)
struct DDGPEAllocSurfaceData{
DDGPEStandardHeader;

int nWidth;
int nHeight;
int nStride;
int nSurfaceFlags;
unsigned char* pBits;
EGPEFormat gpeFormat;
EDDGPEPixelFormat* ddgpePixelFormat
}
Members
- DDGPEStandardHeader
See DDGPEStandardHeader for more information.
- dwCreateFlags
Driver-specific surface creation flags that must be passed to driver's surface allocation implementation.
- nWidth
The desired width of the surface.
- nHeight
The desired height of the surface.
- nStride
The desired stride of the surface.
nSurfaceFlags
GPE surface flags for the surface.Flag Description GPE_REQUIRE_VIDEO_MEMORY
Surface memory must be allocated in video memory.
GPE_PREFER_VIDEO_MEMORY
Surface memory should be allocated in video memory if possible, but can be allocated in system memory, if necessary.
If no flags are set, for example, surfaceFlags is set to zero (0), the surface is allocated in system memory.
- pBits
A pointer to an existing block of video or system memory that is used to store the surface's data.
- gpeFormat
The desired GPE format of the surface.
- ddgpePixelFormat
The desired DDGPE pixel format of the surface.
