|
|
* The function NtGdiDdCanCreateD3DBuffer checks if you can create a
|
|
* surface for DirectX. it redirects to dxg.sys in windows XP/2003,
|
|
* dxkrnl.sys in vista and is fully implemented in win32k.sys in windows 2000 and below

|
* The handle we got from NtGdiDdCreateDirectDrawObject
|

*
|
|
* @param PDD_CANCREATESURFACEDATA puCanCreateSurfaceData
|
|
* This contains information to check if the driver can create the buffers,
|
|
* surfaces, textures and vertexes, and how many of each the driver can create.
|
|
|
|
*
|
|
* @return
|
|
* Depending on if the driver supports this function or not, DDHAL_DRIVER_HANDLED
|
|
* or DDHAL_DRIVER_NOTHANDLED is returned.
|
|
* To check if the function has been successful, do a full check.
|
|
* A full check is done by checking if the return value is DDHAL_DRIVER_HANDLED
|
|
* and puCanCreateSurfaceData->ddRVal is set to DD_OK.
|
|
*
|
|
* @remarks.
|
|
* dxg.sys NtGdiDdCanCreateD3DBuffer and NtGdiDdCanCreateSurface calls are redirected to dxg.sys.
|
|
* Inside the dxg.sys they are redirected to the same function. Examine the memory addresses on the driver list functions
|
|
* table and you will see they are pointed to the same memory address.
|
|
*
|
|
* Before calling this function please set the puCanCreateSurfaceData->ddRVal to an error value such as DDERR_NOTUSPORTED,
|
|
* for the ddRVal will otherwise be unchanged even if an error occurs inside the driver.
|
|
* puCanCreateSurfaceData->lpDD is a pointer to DDRAWI_DIRECTDRAW_GBL, not PDD_DIRECTDRAW_GLOBAL as MSDN claims.
|
|
* puCanCreateSurfaceData->lpDD->hDD also needs be filled in with the handle we got from NtGdiDdCreateDirectDrawObject.
|
|
* puCreateSurfaceData->CanCreateSurface is a pointer to the real functions in the HAL or HEL, that you need fill in.
|
|
* Do not forget PDD_CANCREATESURFACEDATA is typecast of LPDDHAL_CANCREATESURFACEDATA and thuse two struct are different size,
|
|
* the correct struct is LPDDHAL_CANCREATESURFACEDATA.
