用共享存储区方式实现多个进程的通信程序:
该程序通过shmget()函数创建共享存储区,将一个字符串指针指向该存储区的起始地址,然后通过fork()创建两个子进程,通过对该字符串指针的读写达到多进程间的通信。程序中使用sleep()函数调节各进程对共享存储区的读写操作顺序。-With the shared memory area where multiple processes of communication program: the program through the shmget () function, create a shared memory area, a string pointer to the starting address of the store, and then fork () to create two sub-processes, through the read and write pointers to the strings to achieve more inter-process communication. Program, using the sleep () function of regulating the various processes on the shared storage area in order to read and write operations.
