实验三 进程间通信

UNIX/LINUX系统的进程间通信机构（IPC）允许在任意进程间大批量地交换数据。本实验的目的是了解和熟悉LINUX支持的信号量机制、管道机制、消息通信机制及共享存储区机制。

-In Experiment 3, inter-process communication UNIX/LINUX system inter-process communication agencies (IPC) to allow large quantities in any exchange of data between processes. The purpose of this study is to understand and become familiar with LINUX support semaphore mechanism, pipeline system, messaging system and shared storage mechanism.
