2.4实验四：使用命名管道实现进程通信

1、学生姓名：张鹏学号： 150705040实验地点：数计学院407 实验室实验课时： 3 学时实验器材：计算机课程名称：计算机操作系统实验名称：2.4 实验四：使用命名管道实现进程通信一、实验目的1、进一步掌握windows 系统环境下进程通信机制。2、熟悉进程通信API二、实验环境及工具Windows 7操作系统， VC6三、实验内容使用 Windows 系统提供的命名管道完成两个进程之间的通信，要求能正确使用创建命名管道CreateNamePipe（）、连接命名管道ConnectNamePipe（）、拆除命名管道的连接DisconnectNamePipe （）、连接服务器已建立的命名管道Ca
