Linux Programming by Example: The Fundamentals (Prentice Hall Open Source Software Development) (Paperback)

Linux Programming by Example introduces new Linux programmers to the core Linux programming interfaces in a gradual, consistent fashion, progressing intuitively from the basic to the more complex. It covers I/O, file metainformation, users and groups, processes, basic interprocess communication (pipes), general purpose APIs, signals, internationalization, and ends with a chapter on debugging Linux programs. Programmers know that the best way to learn about programming is to study well-written programs. This book teaches the fundamental Linux programming interfaces, those that form the core of any significant program, by presenting example code from real-world production programs that Linux users use every day. By looking at concrete programs, its possible not only to see how to use the Linux programming interfaces, but also to examine the real-world issues (performance, portability, robustness) that arise in writing Linux software. This book is the FIRST in a new series of books featuring Arnold Robbins as Series Editor. The books will all be branded "Linux Programming by Example" and cover programming topics for the new Linux programmer and Windows programmers making the switch.

“This is an excellent introduction to Linux programming. The topics are well chosen and lucidly presented. I learned things myself, especially about internationalization, and I’ve been at this for quite a while.”

—Chet Ramey, Coauthor and Maintainer of the Bash shell

“This is a good introduction to Linux programming. Arnold’s technique of showing how experienced programmers use the Linux programming interfaces is a nice touch, much more useful than the canned programming examples found in most books.”

—Ulrich Drepper, Project Lead, GNU C library

“A gentle yet thorough introduction to the art of UNIX system programming, Linux Programming by Example uses code from a wide range of familiar programs to illustrate each concept it teaches. Readers will enjoy an interesting mix of in-depth API descriptions and portability guidelines, and will come away well prepared to begin reading and writing systems applications. Heartily recommended.”

—Jim Meyering, Coauthor and Maintainer of the GNU Core Utility Programs

This book teaches Linux programming in the most effective way possible: by showing and explaining well-written programs. Drawing from both V7 Unix® and current GNU source code, Arnold Robbins focuses on the fundamental system call APIs at the core of any significant program, presenting examples from programs that Linux/Unix users already use every day. Gradually, one step at a time, Robbins teaches both high-level principles and “under the hood” techniques. Along the way, he carefully addresses real-world issues like performance, portability, and robustness. Coverage includes:

• Memory management
• File I/O
• File metadata
• Processes
• Users and groups
• Sorting and searching
• Argument parsing
• Extended interfaces
• Signals
• Internationalization
• Debugging
• And more…

Just learning to program? Switching from Windows®? Already developing with Linux but interested in exploring the system call interface further? No matter which, quickly and directly, this book will help you master the fundamentals needed to build serious Linux software.
