基于Linux消息队列的简易聊天室(C语言)(附源代码)
采用客户-服务器结构，其中服务器实现各个用户的登录并存储相关信息，客户端通过服务器端获取当前登录用户信息，然后各客户进程通过消息队列实现双向通信。 Linux IPC通信利用消息队列消息机制，多线程通信，字符串处理，链表操作，信号简单处理。消息队列是System V支持一种IPC机制，通过类似链表的操作向一个FIFO里通过msgsnd发送用户自定义数据，进程可以通过msgrcv来接收指定类似mtype的数据，从而实现进程间通信。在服务器端实现广播功能，以及服务器退出以后通知；所有客户端退出并删除消息队列功能；对所有客户端的统计由链表实现在客户端实现：上线提醒，下线提醒，服务器断线后
