Introduction

Rich Stevens and I first met through an e-mail exchange when I reported a typographical error in his first book, UNIX Network

Programming . He used to kid me about being the person to send him his first errata notice for the book. Until his death in 1999, we

exchanged e-mail irregularly, usually when one of us had a question we thought the other might be able to answer. We met for dinner at

USENIX conferences and when Rich was teaching in the area.

Rich Stevens was a friend who always conducted himself as a gentleman. When I wrote UNIX System V Network Programming in 1993,

I intended it to be a System V version of Rich's UNIX Network Programming . As was his nature, Rich gladly reviewed chapters for me,

and treated me not as a competitor, but as a colleague. We often talked about collaborating on a STREAMS version of his TCP/IP

Illustrated book. Had events been different, we might have actually done it, but since Rich is no longer with us, revising Advanced

Programming in the UNIX Environment is the closest I'll ever get to writing a book with him.

When the editors at Addison-Wesley told me that they wanted to update Rich's book, I thought that there wouldn't be too much to

change. Even after 13 years, Rich's work still holds up well. But the UNIX industry is vastly different today from what it was when the

book was first published.

The System V variants are slowly being replaced by Linux. The major system vendors that ship their hardware with their own

versions of the UNIX System have either made Linux ports available or announced support for Linux. Solaris is perhaps the

last descendant of UNIX System V Release 4 with any appreciable market share.

After 4.4BSD was released, the Computing Science Research Group (CSRG) from the University of California at

Berkeley decided to put an end to its development of the UNIX operating system, but several different groups of volunteers

still maintain publicly available versions.

The introduction of Linux, supported by thousands of volunteers, has made it possible for anyone with a computer to run an

operating system similar to the UNIX System, with freely available source code for the newest hardware devices. The

success of Linux is something of a curiosity, given that several free BSD alternatives are readily available.

Continuing its trend as an innovative company, Apple Computer abandoned its old Mac operating system and replaced it with

one based on Mach and FreeBSD.

Thus, I've tried to update the information presented in this book to reflect these four platforms.

After Rich wrote Advanced Programming in the UNIX Environment in 1992, I got rid of most of my UNIX programmer's manuals. To this

day, the two books I keep closest to my desk are a dictionary and a copy of Advanced Programming in the UNIX Environment . I hope

you find this revision equally useful.

Changes from the First Edition

Rich's work holds up well. I've tried not to change his original vision for this book, but a lot has happened in 13 years. This is especially

true with the standards that affect the UNIX programming interface.

Throughout the book, I've updated interfaces that have changed from the ongoing efforts in standards organizations. This is most

noticeable in Chapter 2 , since its primary topic is standards. The 2001 version of the POSIX.1 standard, which we use in this revision, is

much more comprehensive than the 1990 version on which the first edition of this book was based. The 1990 ISO C standard was

updated in 1999, and some changes affect the interfaces in the POSIX.1 standard.

A lot more interfaces are now covered by the POSIX.1 specification. The base specifications of the Single UNIX Specification (published

by The Open Group, formerly X/Open) have been merged with POSIX.1. POSIX.1 now includes several 1003.1 standards and draft

standards that were formerly published separately.

Accordingly, I've added chapters to cover some new topics. Threads and multithreaded programming are important concepts because

they present a cleaner way for programmers to deal with concurrency and asynchrony.

The socket interface is now part of POSIX.1. It provides a single interface to interprocess communication (IPC), regardless of the location

of the process, and is a natural extension of the IPC chapters.

I've omitted most of the real-time interfaces that appear in POSIX.1. These are best treated in a text devoted to real-time programming.

One such book appears in the bibliography.

I've updated the case studies in the last chapters to cover more relevant real-world examples. For example, few systems these days are

connected to a PostScript printer via a serial or parallel port. Most PostScript printers today are accessed via a network, so I've

changed the case study that deals with PostScript printer communication to take this into account.

The chapter on modem communication is less relevant these days. So that the original material is not lost, however, it is available on the

book's Web site in two formats: PostScript ( http://www.apuebook.com/lostchapter/modem.ps ) and PDF

( http://www.apuebook.com/lostchapter/modem.pdf ).

The source code for the examples shown in this book is also available at www.apuebook.com . Most of the examples have been run on

four platforms:

FreeBSD 5.2.1, a derivative of the 4.4BSD release from the Computer Systems Research Group at the University of

California at Berkeley, running on an Intel Pentium processor

1 .

Linux 2.4.22 (the Mandrake 9.2 distribution), a free UNIX-like operating system, running on Intel Pentium processors 2 .

Solaris 9, a derivative of System V Release 4 from Sun Microsystems, running on a 64-bit UltraSPARC IIi processor 3 .

Darwin 7.4.0, an operating environment based on FreeBSD and Mach, supported by Apple Mac OS X, version 10.3, on a

PowerPC processor

4 .
