此书为POSIX多线程程序设计中文版。本书深入描述了IEEE的开放系统接口标准-POSIX线程，通常称为Ptherads标准。本书首先解释了线程的基本概念，包括异步编程、线程的生命周期和同步机制；然后讨论了题，并给出了避免错误和提高性等问题的有价值的建议。本书使用了大量注释过的实例来解释实际的概念，并包括Pthreads的简装索引和对标准化的展望。本书适合有经验的C语言程序员阅读，也适合多线程编程人员参考。 -This book describes in depth the open system interface standard IEEE-POSIX threads, commonly known as Ptherads standards. This book first explains the basic concepts of threads, including asynchronous programming, thread life cycle and synchronization mechanisms　and then discuss the topic, and gives avoiding mistakes and issues such as Ti Gao Xing valuable suggestions. This book uses a lot of comments over the examples to explain the concept of reality, and includes a slimmed-down Pthreads standard index and on the prospects. Book for experienced C language programmers to read, also suitable for multi-threaded programming for reference.
