About This Manual

This manual provides an overview of high-level programming with open network computing remote procedure calls (ONC RPC), describes how to use the rpcgen protocol compiler to create applications, and describes the RPC programming interface. See rpcgen(1) for more information.

Audience

This guide assumes a knowledge of network theory and is for experienced programmers who want to write network applications using open-network computing remote procedure calls (ONC RPC) without needing to know about the underlying network.

Organization

This guide contains three chapters, an appendix, and an index:

Chapter 1	Provides an overview of high-level programming through remote procedure calls (RPC), and discusses the RPC model and versions, external data representation, and RPC independence from network transport protocol. This chapter is for anyone interested in ONC RPC.
Chapter 2	Describes how to write RPC client and server applications with the `rpcgen` protocol compiler. It also provides some information on `rpcgen`, client and server programming, debugging applications, the C preprocessor, and RPC language syntax. This chapter also describes how to create routines for external data representation (XDR). This chapter is for programmers who want to use `rpcgen` to write RPC-based network applications.

Chapter 3	Describes the RPC programming interface layers, XDR serialization defaults, raw RPC, and miscellaneous RPC features. This chapter is for programmers who need to understand RPC mechanisms to write customized network applications.
Appendix A	Contains additional notes on the XDR library. This appendix is for programmers who want to implement RPC and XDR on new machines.

Icons on Tru64 UNIX Printed Books

The printed version of the Tru64 UNIX documentation uses letter icons on the spines of the books to help specific audiences quickly find the books that meet their needs. (You can order the printed documentation from Compaq.) The following list describes this convention:

G	Books for general users
S	Books for system and network administrators
P	Books for programmers
D	Books for device driver writers
R	Books for reference page users

Some books in the documentation help meet the needs of several audiences. For example, the information in some system books is also used by programmers. Keep this in mind when searching for information on specific topics.

The Documentation Overview provides information on all of the books in the Tru64 UNIX documentation set.

% $: A percent sign represents the C shell system prompt. A dollar sign represents the system prompt for the Bourne, Korn, and POSIX shells.
% cat: Boldface type in interactive examples indicates typed user input.
file: Italic (slanted) type indicates variable values, placeholders, and function argument names.
[ | ] { | }: In syntax definitions, brackets indicate items that are optional and braces indicate items that are required. Vertical bars separating items inside brackets or braces indicate that you choose one item from among those listed.
colored text: In syntax definitions, literal elements are colored green. Variable values, placeholders, and function argument names are colored red. No special colored text is used outside of syntax descriptions.
. . .: In syntax definitions, a horizontal ellipsis indicates that the preceding item can be repeated one or more times.
cat(1): A cross-reference to a reference page includes the appropriate section number in parentheses. For example, cat(1) indicates that you can find information on the cat command in Section 1 of the reference pages.
