用共享内存，信号灯，以及互斥锁实现进程，线程间的通信，来模拟三国问题-using shared memory, lights, and Mutex realization process, the communication between threads, to simulate the three issues

Linux内核分析实验 本实验实现车辆过隧道的模拟，其中最关键的是信号灯实现进程同步以及共享内存的实现。-Linux kernel analysis of the experimental realization of experimental simulation of the vehicle through the tunnel, one of the most critical is the signal to achieve process synchronization and sha
