Abstract
A method, apparatus and program storage device that provides a user mode device interface for enabling software reuse. The user mode device interface allows device interface requests to be sent and received, including commands and data structures, via socket communication. A device state machine on the client side is implemented in a set of shared functions that can be incorporated by all applications that want to communicate to a particular service provider. The service provider offers the software functions over a user mode device interface via socket communication. The device state machine on the service provider side is embedded in the socket server implementation. The interaction between the state machines on both client and server sides ensures a device interface request is properly handled.
