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.
