DdGetDxHandle function (ddrawgdi.h)
[This function is subject to change with each operating system revision. Instead, use the Microsoft DirectDraw and Microsoft Direct3DAPIs; these APIs insulate applications from such operating system changes, and hide many other difficulties involved in interacting directly with display drivers.]
Returns the kernel-mode Microsoft DirectX API handle to use in subsequent calls to the kernel-mode entry points that control the DirectX API mechanism.
GdiEntry14 is defined as an alias for this function.
HANDLE DdGetDxHandle( [in] LPDDRAWI_DIRECTDRAW_LCL pDDraw, [in] LPDDRAWI_DDRAWSURFACE_LCL pSurface, [in] BOOL bRelease );
Pointer to the DirectDraw object owning the surface. This parameter is optional and may be set to NULL.
Pointer to the surface for which to return a kernel-mode DirectX API handle. This parameter is optional and may be set to NULL.
Set to TRUE if the DirectX API kernel mode interface should be released. Otherwise, FALSE.
A DirectX API handle used in subsequent DirectX API-oriented kernel entry points.
If both pDDraw and pSurface are specified, pSurface is ignored.
