DirectInput
XInput, an API for "next generation" controllers, was introduced in December 2005 alongside the launch of the Xbox 360. This instruction set provided full support for Xbox 360 controllers in Windows XP SP1 and subsequent operating systems, and is described by Microsoft as being easier to program for and requiring less setup than DirectInput. XInput is compatible with DirectX version 9 and later.
