2023年实验报告实验七

浙江大学都市学院试验汇报课程名称___________操作系统原理试验_______________试验项目名称试验七进程通信一一消息队列学生姓名潘唯帆专业班级计算1003学号31001172试验成绩指导老师（签名）日期_____________注意•务请保留好各自日勺源代码，已备后用•请上传到平台BB

1.一.试验目日勺和规定

2.理解Linux系统的进程间通信机构（IPC）；

3.理解Linux有关消息队列的概念；

4.掌握Linux支持消息队列的系统调用；

5.巩固进程同步概念

二、试验内容实现并发进程间消息的发送与接受

三、试验环节消息的发送与接受

1.）编译运行给出日勺和观测运行成果1client.c server.c,#include sys/msg.h#include sys/ipc.h#define MSGKEY75struct msgformlong mtype;char mtext
