Linux Programming By Example

Craig Maloney writes "Linux Programming By Example is a book aimed squarely at programmers learning how to program the Linux and UNIX system for the first time." Read Craig's review of Linux Programming by Example (below) to find his take on whether the book delivers on the promise of its title. Linux Programming By Example author Kurt Wall pages 533 publisher QUE (InformIT) rating 9/10 reviewer Craig Maloney ISBN 0789722151 summary Linux Programming by Example is a concise and solid introduction to programming under the Linux system. Excellent instructions accompany fully-working examples of code.

There are plenty of books on this topic as any trip to the bookstore will show. Where this book excels compared with other Linux programming books is its consistent focus throughout. Other books tend to explain a multitude of concepts without relating them back to a real-world example. In Linux Programming By Example, the author introduces a concept, and explains it with an example. In the last chapter, the author integrates the knowledge he's presented, utilizing many of the book's concepts in building a simple CD-Database program. Of course, not all of the concepts relate to the final CD database (The chapters TCP/IP Programming, The Sound API and Using the Mouse are not referred to in the final program), but it's helpful for beginning programmers unsure how all of these pieces fit in the bigger picture of a working program.

Begin at the beginning

Linux Programming By Example begins with topics that don't get covered until the end of many books. The book starts by discussing how to use GCC and make on a Linux machine, and how to create a Makefile. It's always puzzled me why some books don't cover the compiler or the make process until the end of the book. What's the point in that? Granted, chapters in debugging and RCS are left to the end of the book, but presenting key concepts in the development process early in the book helps the reader to get a better feel for how all of these concepts interrelate in a Linux/UNIX environment.

Moving forward

From the basics of compilation and making programs, the book moves to the basics of a Linux system in Part II: System Programming. This is where the book truly shines. In the section on processes, Wall discusses the elements that make up a process, how to manipulate a process, and why you would want to do this anyway. The book assumes no prior UNIX knowledge, but doesn't plod along like most introductory texts. In the section on signals, the book defines what signals are, early signal APIs and their issues, POSIX and Linux signal APIs, and how to use signals and signal sets. In this chapter, the author not only lists the signals supported by the Linux system, but also other signals supported by POSIX and other UNIX systems. While this might sound confusing, the author takes time out to explain which signals are really important in a Linux environment. This is a key reason why this book retains its readability without losing depth. Each chapter in the System Programming portion of the book retains this format -- not only demonstrating what the topic is, but also where this fits in a Linux/UNIX system and why you would even bother to know this in the first place.

What's good?

Linux Programming By Example is clearly aimed at getting programmers up to speed on not only programming Linux systems, but also POSIX based systems. Wherever possible, the author makes a point of pointing out the POSIX way. This book could have been easily called POSIX Programming by Example. The author also makes no bones about implementation issues with Linux and the POSIX or System V way of implementation. The book clearly states where Linux falls short of the full POSIX standard, and where pitfalls with porting code from other systems may occur. It's a refreshing change from other beginner texts which assume the reader will discover these pitfalls on their own.

So what's in it for me?

If you're looking for a quick, effective way to get up to speed in Linux and UNIX programming without breaking the bank, Linux Programming by Example is the book to take you there. This book is designed for programmers who are familiar with programming on other systems but haven't dealt with Linux before.

You might have trouble locating this book, since QUE let it lapse for a while, but there should be another batch hitting stores soon. You won't be disappointed.

Yeah, that was a great book. I tried the motor rev mod on one of my 752i, but the example in the book had a bug in it, and my car exploded.
