ABSTRACT:
A method and apparatus for providing kernel mode support for fast IPC between a client process and a server process. A client application accesses a kernel mode of an operating system via a device driver or similar method. The client creates an abstract "resource" data type and derives a client port therefrom. The client port references a call structure containing object call data. The call is transported via a transport agent to the server. The server accesses the kernel mode of the operating system and creates a resource data type and a server port derived from the resource type. The server awaits calls from the clients using the server port. When a call arrives, the server port extracts the data from the call structure and performs the requested service. The server port then transmits a response back to the client. The use of the abstract resource data type permits portability across different operating systems and platforms.
