ABSTRACT:
A method and system of transparently supporting functionalities on different versions of an operating system (O/S). An application is provided that determines if an O/S executing on a processor provides an O/S service layer. If the O/S service layer is provided, the application loads the O/S service layer. If no O/S service layer is provided, the O/S loads an alternative service layer which emulates a subset of the service provided by the O/S service layer. Regardless of the service layer loaded, the application follows the same flow path after the service layer is loaded.
