With the rapid development of the Internet, more and more systems use UNIX and Linux as server hosts, and because of the stability and security of this operating system, there are more and more application services based on UNIX and Linux. Mastering the programming technology based on UNIX and Linux environments has become a necessary skill for relevant network administrators, network application developers and network security personnel.
Executive summary
This book introduces in detail the basic programming methods based on TCP/P network interface under LUNIX/Linux system, including iterative and concurrent server programming methods, process and thread programming techniques, I/O programming techniques, IPv4 and IPv6 compatibility, original Interface, data link access technology, broadcast and multicast technology, etc. In order to meet the actual needs of teaching, in the last chapter of this book, five experimental instructions are given: Socket basic programming, server-single client connection processing, multi-process server template, multi-thread writing template, and thread-specific data TSD implementation template. In the relevant chapters of the book, the editors have cited at least one complete example to illustrate the problem. Learners can learn advanced Linux/UNIX programming by doing the basic experiments in the book and verifying them through the experiments in the relevant chapters.
