Preface

This manual describes the programmatic interfaces to transport services in the Solaris operating system.

In this guide the terms SunOS and Solaris are used interchangeably because the interfaces described in this manual are common to both. Solaris 2.5, SunSoft's^(TM) distributed computing operating environment, is a superset of SunOS. It is comprised of SunOS release 5.5 with ONC+^(TM), OpenWindows^(TM), ToolTalk^(TM), DeskSet^(TM), OPEN LOOK^(R), and other utilities. This release of Solaris is fully compatible with System V, Release 4 (SVR4) and conforms to the third edition of the System V Interface Description (SVID). It supports all System V network services.

Who Should Use This Book

The guide assists you in developing a networked, distributed application in the Solaris operating system.

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

How This Book Is Organized

Chapter 1, "Introduction to Network Programming Interfaces," gives a high-level introduction to networking concepts and the topics covered in this book.

Chapter 2, "Programming With Sockets," describes the socket interface at the transport layer.

Chapter 3, "Programming With the Transport Layer Interface (TLI)," describes the UNIX System V Transport Interface.

Chapter 4, "Transport Selection and Name-to-Address Mapping," describes the network selection mechanisms used by applications in selecting a network transport and its configuration.
