Open Network Computing (ONC) Remote Procedure Call (RPC), commonly known as Sun RPC is a remote procedure call system. ONC was originally developed by Sun Microsystems in the 1980s as part of their Network File System project.

Sun RPC Information Al.l RPC Source Code Availability The source code for the SunOS 4.0 RPC and XDR Library, referred to as RPCSRC 4.0, is a license-free version of Sun's RPC and XDR Library. RPCSRC is available free to anyone with access to the Internet via an anonymous file-transfer program (ftp) login from one of the RPCSRC archive sites.

RPC is a language construct, meaning it is a property of the programming language (since it deals with the semantics of function calls). However, no languages support Sun RPC, so a pre-compiler must be used to generate the stub functions on the client and the server. The Sun RPC compiler is called rpcgen. As input, it takes a list of remote

Sun ONC RPC provides an advanced client/server programming environment that is easy to use, allowing you to build applications that execute procedures on other network computers without having to deal with the fact that the procedures are not executed locally.

Originally developed by Sun, but now widely available on other platforms (including Digital Unix). Also known as Open Network Computing (ONC). Sun RPC package has an RPC compiler (rpcgen) that automatically generates the client and server stubs.

SunRpc: an RPC protocol compiler Version. 4.0. Description. rpcgen is a tool that generates C code to implement an RPC protocol. The input to rpcgen is a language similar to C known as RPC Language (Remote Procedure Call Language).

Sun RPC is sometimes called ONC (Open Network Computing) RPC. Sun RPC is supplied as a part of the various Sun UNIX operating systems and is also available with other NFS installations. Implementers have the choice of using remote procedure calls over either UDP/IP or TCP/IP.

This section provides an overview of TI-RPC, also known as Sun RPC. The information presented is most useful to someone new to RPC. See the Glossary for the definition of the terms used in this guide.

THE RPC MODEL The Sun RPC protocol is based on the remote procedure call model, which is similar to the local procedure call model. In the local case, the caller places arguments to a procedure in some well- specified location (such as a register window).

Sun RPC is a fairly complete implementation of Sun's remote procedure call protocol. This implementation is compatible with Sun's native implementation. The interface to our implementation of Sun RPC in no way resembles Sun's.
