ONC+ Developer's Guide

Preface

The ONC+ Developer's Guide describes the programming interfaces to remote procedure call (RPC) and NIS+, a network name service, which belong to the ONC+TM distributed services developed at Sun MicrosystemsTM, Inc.

In this guide, the terms SunOSTM and SolarisTM are used interchangeably because the interfaces described in this manual are common to both. Solaris 8 is Sun Microsystem's distributed computing operating environment. It is comprised of SunOS release 5.8 with the ONC+ technologies, OpenWindowsTM, ToolTalkTM, DeskSetTM, and OPEN LOOK® as well as other utilities.

All utilities, their options, and library functions in this manual reflect the current Solaris system software developed by Sun Microsystems Inc. If you are using a previous version of Solaris system software, some utilities and library functions may function differently.

Who Should Use This Guide

The guide assists you in converting an existing single-computer application to a networked, distributed application, or devloping and implementing distributed applications.

Use of this guide assumes basic competence in programming, a working familiarity with the C programming language, and a working familiarity with the UNIX® operating system. Previous experience in network programming is helpful, but is not required to use this manual.

How This Guide Is Organized

Part One--Introduction

Chapter 1, Introduction to ONC+ Technologies gives a high-level introduction to the ONC+ distributed computing platform and services.

Part Two--Remote Procedure Call (RPC)

Chapter 2, Introduction to TI-RPC introduces TI-RPC.

Chapter 3, rpcgen Programming Guide describes how the rpcgen tool generates client and server stubs.

Chapter 4, The Programmer's Interface to RPC describes the use of RPC in the programming environment.

Part Three--NIS+ Applications Programming Interface

Chapter 5, NIS+ Programming Guide describes the NIS + applications programming interface.

Appendixes

Appendix A, XDR Technical Note describes XDR and how it is used in data formatting and type conversion.

Appendix B, RPC Protocol and Language Specification describes the protocol of RPC usage, both syntax and limitations.

Appendix C, XDR Protocol Specification describes the XDR protocol and language.

Appendix D contains complete functional listings of some of the code included in the document as examples.

Appendix E, The portmap Utility describes the portmap utility and its function. This appendix is included in this document to aid migrating applications written to run on earlier releases of SunOS.

Appendix F, Writing a Port Monitor With the Service Access Facility (SAF) describes the process of writing a port monitor application under the SAF and is included as a reference for applications development.
