    If you are an experienced C programmer with a working knowledge of UNIX, you cannot afford to be without this up-to -date tutorial on the system call interface and the most important functions found in the ANSI C library. Richard Stevens describes more than 200 system calls and functions; since he believes the best way to learn code is to read code,a brief example accompanies each description. Building upon information presented in the first 15 chapters, the author offers chapter-long examples teaching you how to create a database library, a PostScript printer driver, a modem dialer, and a program that runs other programs under a pseudo terminal. To make your analysis and understanding ofthis code even easier, and to allow you to modify it, all of the code in the book is available via UUNET. Advanced Programming in the UNIX Environment is applicable to all major UNIX releases, especially System V Release the latest release of 4.3BSD, including 386BSD. These real-world implementations allow you to more clearly understand the status of the current and future standards,including IEEE POSIX and XPG3.
