This book teaches Linux programming in the most effective way possible: by showing and explaining well-written programs. Drawing from both V7 Unix and 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 addressses real world issues like performance, portability, and robustness. - Back cover.
