On realizing process coordination and mutual exclusion throngh P.V operation

文章首先阐述了进程同步与互斥和P、V操作的基本概念 ;然后深入探讨了用P、V操作实现进程同步与互斥的基本方法及遇到实际问题时的解决方案 :最后对“生产者———消费者”和“读者———写者”两个经典事例的实现作了具体的描述。

This article discusses the basic concepts of process coordination and mutual exclusion and P?V operation. Second it probes deep into basic methods of realizing process coordination and mutual exclusion through P?V operation, and solutions to practical problems. Finally,this articles describes the realization of two typical examples:'producer-consumer' and 'reader-writer.
