IOSurface is private CoreFoundation frameworks for managing pixel buffers, or in official words, "sharing graphics surfaces between applications"[1]. It is also a public framework in Mac OS X 10.6 (Snow Leopard).
In 2.x the same function is provided by the CoreSurface framework. On 3.x CoreSurface is deprecated, and its functions are now wrappers of the corresponding IOSurface functions.
