For more than twenty years, serious C programmers have relied on one book for practical, in-depth knowledge of the programming interfaces that drive the UNIX and Linux kernels: W. Richard Stevens' Advanced Programming in the UNIX Environment. Now, once again, Rich's colleague Steve Rago has thoroughly updated this classic work for the modern developer.
The new third edition supports today's leading platforms, reflects new technical advances and best practices, and aligns with Version 4 of the Single UNIX Specification. Steve carefully retains the spirit and approach that have made this book so valuable while bringing it firmly into the 21st century.
Building on Rich's pioneering work, the book begins with files, directories, and processes, carefully laying the groundwork for more advanced techniques like signal handling and terminal I/O. You'll also dive deep into threads and multithreaded programming, plus socket-based IPC that's essential for network applications.
This edition covers more than seventy new interfaces, including POSIX asynchronous I/O, spin locks, barriers, and POSIX semaphores. Nearly all examples have been tested on four modern platforms: Solaris 10, Mac OS X version 10.6.8 (Darwin 10.8.0), FreeBSD 8.0, and Ubuntu version 12.04 (based on Linux 3.2). You can be confident the code works in real production environments.
Just like previous editions, you'll learn through concrete examples, including more than ten thousand lines of downloadable, ISO C source code. More than four hundred system calls and functions are demonstrated with concise, complete programs that clearly illustrate their usage, arguments, and return values. The book also presents several chapter-length case studies that tie together everything you've learned.
Whether you're building system utilities, network servers, or complex applications, Advanced Programming in the UNIX Environment provides the knowledge and confidence to write code with exceptional power, performance, and reliability.
