说明：  Linux-UNIX系统编程手册 《linux/unix系统编程手册》是介绍linux与unix编程接口的权威著作。linux编程资深专家michael kerrisk在书中详细描述了linux/unix系统编程所涉及的系统调用和库函数，并辅之以全面而清晰的代码示例。《linux/unix系统编程手册》涵盖了逾500个系统调用及库函数，并给出逾200个程序示例，另含88张表格和115幅示意图。
(The Linux Programming Interface describes the Linux API (application programming interface)-the system calls, library functions, and other low-level interfaces that are used, directly or indirectly, by every program that runs on Linux. Programs that explicitly use these interfaces are commonly called system programs, and include applications such as shells, editors, windowing systems, terminal emulators, file managers, compilers, database management systems, virtual machines, network servers, and much of the other software that is employed on a daily basis on Linux systems. Extensively indexed and heavily cross-referenced, The Linux Programming Interface is both an introductory guide for readers new to the topic of system programming, and a comprehensive reference for experienced system programmers. Although this book goes into detail on a wealth of Linux-specific features, it gives careful attention to contemporary Unix programming standards and to portability issues.)
