Advanced Programming in the UNIX Environment (Addison-Wesley Professional

Description: The new third edition of Advanced Programming in the UNIX® Environment supports today's leading platforms, reflects new technical advances and best practices, and aligns with Version 4 of the Single UNIX Specification. This valuable tool begins with files, directories, and processes, carefully laying the groundwork for more advanced techniques, such as signal handling and terminal I/O then thoroughly covers threads and multithreaded programming, and socket-based IPC. This edition covers more than seventy new interfaces, including POSIX asynchronous I/O, spin locks, barriers, and POSIX semaphores. Students are given 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. To tie together what they've learned, the book presents several chapter-length case studies, each reflecting contemporary environments.
