摘　　要：基于C语言开发环境,在Linux操作系统的基础上,对即时通信系统的实现流程进行了系统的研究与介绍。介绍了软件编程所用的模式,设计了即时通信软件所用的协议,通过有效状态图使服务器端和客户端的各个状态之间的关系清晰,主要对各个模块的实现方式进行了详细介绍,使软件实现了基本的注册、登陆、消息、列表、更新和下线等功能,初步满足了基本的聊天需求。通过运行、测试与分析,该软件运行稳定、可靠。The implementation flow of instant communication system is systematically studied and introduced based on C language development environment and Linux-based operating system. The programming model of this software is introduced and the protocol used by instant communication software is designed. The relationship between all kinds of status of server and client is clearly displayed through the effective state diagram. The implement method of each model is described in detail in order to achieve such basic functions as registration,log on,message,listing,update and log off,and can meet preliminarily the requirement of chat. The results of operation,test and analysis show that the instant communication software is stable,reliable.
