模拟“五个哲学家”问题该实验的要点是，解决并发环境下，多进程之间的同步与互斥问题。进程间的同步互斥必然涉及进程间的通信（信息交换）。-Simulation of the " five philosophers" problem of the main points of the experiment, the solution to complicated circumstances, between the multi-process synchronization and

分别利用UNIX的消息通信机制、共享内存机制（用信号灯实施进程间的同步和互斥）实现两个进程间的数据通信。具体的通信数据可从一个文件读出，接收方进程可将收到的数据写入一个新文件，以便能判断数据传送的正确性（对文件操不熟悉的同学可不必通过读写文件，只要键盘输入和输出至屏幕进行比较即可）。 -, Respectively, using the information communication mechanism UNIX, shared memory mechanism (with tr
