摘要
ＩＰＣ机制是ＵＮＩＸ系统提供的一个用于进程间通信的软件包，包括消息、信号量和共享内存３种。本文论述了ＩＰＣ机制提供给用户的命令级接口和程序设计接口，对ＩＰＣ机制内部的数据结构和主要的实现算法进行了剖析。
Three kinds of IPC (InterProcess Communication) mechanisms have been in- troduced into UNIX -style operating system since the ATδT UNIX SVR4. 0 was developed. They are message. semaphores set and shared-memory. In this paper. we present command level and programming level interfaces provided for users. We also describe main internal da- ta structures and algorithms which are adopted in the three IPC mechanisms.
