The Oracle Solaris OS provides ONC+ distributed services for making remote procedure calls (RPC). The ONC+ Developer’s Guide describes the ONC+ distributed services that were developed at Sun.
ONC+ technologies consist of a family of technologies, services, and tools:
Remote procedure calls (RPC).
Transport-independent remote procedure calls (TI-RPC) to make RPC applications transport independent.
External data representation (XDR), an architecture-independent specification for representing data.
The book contains information on the rpcgen tool and the portmap utility. The book also contains code examples on the use of RPC.
