A client process resides on a host computer within a distributed data processing system, and the client process requests a remote procedure call for a service procedure. A binding handle of a server process is obtained; a determination is made as to whether the binding handle of the server process points to the client process; and in response to a determination that the binding handle of the server process points to the client process, a positive indication is generated that the service procedure is provided by the client process. In response to a determination that the service procedure is provided by the client process, the service procedure is called using a local procedure call after obtaining a local address for the function within the client process by looking up the service procedure in an interface registry.

Method and system for converting a remote procedure call to a local procedure call when the service is on the same device as the calling client

A DCE RPC mechanism normally uses a TCP/IP-based transport service to enable client machines to make remote procedure calls to server machines in a distributed computing environment. NETBIOS protocol support for the RPC mechanism is provided by using NETBIOS application names similar to TCP/IP conventions and through use of connection-oriented or connection-less NETBIOS protocol sequences. In particular, NETBIOS names are used as though they include a fixed portion representing a machine, and a dynamic portion representing an application on that machine. New functions are provided to use NETBIOS names in place of TCP/IP addresses and these NETBIOS names are then used via the sockets API, leaving RPC's use of the sockets API unchanged.
