Advanced programming in the Unix environment

This book is a definitive reference for serious and professional UNIX systems programmers.

It covers the application programming interface of the UNIX family of operating systems, including system calls for file operations, process management, inter-process communication, signals, and terminal I/O.

The second and third editions, updated by Stephen A. Rago, include support for modern platforms such as FreeBSD, Linux, Solaris, and Darwin, as well as coverage of multithreaded programming with POSIX Threads.

The book provides numerous examples and case studies, including the implementation of a database library and a print spooling process, to illustrate the practical application of UNIX programming concepts.
