DirectDraw Object struct
|
|
|
|
DDRAWI_DIRECTDRAW_INT
|
|
it is the the return pointer from ddraw.dll to the program
|
|
|
|
DDRAWI_DIRECTDRAW_LCL
|
|
It is the program own private data
|
|
|
|
DDRAWI_DIRECTDRAW_GBL
|
|
This struct is gboal for whole ddraw.dll for all program
|
|
it is static in ddraw if it change it change for all
|

program
|
|
|
|
The struct
|
|
|
|
from http://msdn2.microsoft.com/en-us/library/ms898267.aspx
|
|
it was not document for windows 2000/xp/2003 but ms did document it
|
|
for windows ce 5.0 the link are to windows ce 5.0 arch

The following informations might be incorrectly
|
|
I am using logic thinking since the info does
|
|
not exists in MSDN so I am drawing clue how
|
|
previews stuffs works that are document in MSDN/DDK
|
|
|
|
follow struct should exists ???
|
|
DDRAWI_DDVIDEOPORT_GBL
|
|
DDRAWI_DDGAMMACONTROL_INT
|
|
DDRAWI_DDGAMMACONTROL_LCL
|
|
DDRAWI_DDGAMMACONTROL_GBL
|
|
DDRAWI_DDCOLORCONTROL_INT
|
|
DDRAWI_DDCOLORCONTROL_LCL
|
|
DDRAWI_DDCOLORCONTROL_GBL
|
|
DDRAWI_KERNEL_INT
|
|
DDRAWI_KERNEL_LCL
|
|
DDRAWI_KERNEL_GBL
|
|
DDRAWI_DDKERNELSURFACE_INT
|
|
DDRAWI_DDKERNELSURFACE_LCL
|
|
DDRAWI_DDKERNELSURFACE_GBL
|
|
|
|
follow struct can be easy create
|
|
DDRAWI_DDGAMMACONTROL_INT
|
|
DDRAWI_DDCOLORCONTROL_INT
|
|
DDRAWI_KERNEL_INT
|
|
|
|
the DDRAWI_DDGAMMACONTROL_INT should looking like this
|
|
typedef struct _DDRAWI_DDGAMMACONTROL_INT
|
|
{
|
|
LPVOID lpVtbl;
|
|
LPDDRAWI_DDGAMMACONTROL_LCL lpLcl;
|
|
LPDDRAWI_DDGAMMACONTROL_INT lpLink;
|
|
DWORD dwIntRefCnt;
|
|
} DDRAWI_DDGAMMACONTROL_INT, *LPDDRAWI_DDGAMMACONTROL_INT
|
|
|
|
how did I got this struct I looked at all other INT struct how they where
|
|
build. But it is not 100% sure this one is right untill I/we known how
|
|
the DDRAWI_DDGAMMACONTROL_LCL works and DDRAWI_DDCOLORCONTROL_GBL
|
|
our internal struct will look like this
|
|
|
|
typedef struct _DDRAWI_DDGAMMACONTROL_INT
|
|
{
|
|
LPVOID lpVtbl;
|
|
LPVOID lpLcl;
|
|
LPVOID lpLink;
|
|
DWORD dwIntRefCnt;
|
|
} DDRAWI_DDGAMMACONTROL_INT, *LPDDRAWI_DDGAMMACONTROL_INT
|
|
|
|
same goes for DDRAWI_DDCOLORCONTROL_INT
|
|
|
|
typedef struct DDRAWI_DDCOLORCONTROL_INT
|
|
{
|
|
LPVOID lpVtbl;
|
|
LPVOID lpLcl;
|
|
LPVOID lpLink;
|
|
DWORD dwIntRefCnt;
|
|
} DDRAWI_DDCOLORCONTROL_INT, *LPDDRAWI_DDCOLORCONTROL_INT
|
|
|
|
|

|
|
