Introduction:
Computer books
The Unix/Linux Programming Tutorial follows the latest "unified UNIX Specification Version 4" and systematically describes programming methods for various functions of UNIX APIs on the Linux platform. This book covers the development history and standards of UNIX, standard I/O and low-level I/O, file and directory operations, process environment and process control, signal processing, time and timing, terminal I /O, advanced I/O, inter-process communication, socket-network communication, and multi-thread programming.
The Unix/Linux Programming Tutorial introduces the functions and usage of various functions of UNIX APIs, and clearly describes the basic operating system principles they imply. The book provides a large number of program design examples, which helps readers better master the functions, usage methods and programming skills of these functions.
The Unix/Linux programming course is particularly suitable for computer teachers in colleges and universities, Senior undergraduates, and graduate students as teaching materials and reference books, it is also particularly suitable for engineers and technicians engaged in computer system software and application software development as practical programming manuals.
