Used in server design and implementation of multithreading technology, in a single program which is running a number of different threads to perform different tasks. Greatly enhanced the program on the use of server resources. To write and debug serverside program and client program under Linux, the connection between the client, server and munications. Two windows can be opened up on a standalone client and server, or the two hosts links, respectively, as the client and server. Overall, this design embedded C language for the development of language, the use of work sockets 2 socket connection is established and run multithreaded data exchange program GCC debugging can be used in standalone work. Keywords: TCP / IP。 可以在單機上開辟兩個窗口實現(xiàn)客戶端和服務器，或者兩臺主機鏈接分別作為客戶端和服務器。大大增強了程序對服務器資源的利用。 1 Linux 下 網(wǎng)絡聊天室的設計與實現(xiàn) 林仁明 計算機學院通信工程專業(yè) 2021 級 指導老師：岳淼 摘要 ： 本 系統(tǒng)采用 C/S 結合的結構 ，客戶端與客戶端以及客戶端與服務器端之間 通過 基于 TCP/IP 協(xié)議 Socket 套接口 傳送消息。服務器設計與實現(xiàn)過程中 采用了多線程技術，可以在單個程序當中同時運行多個不 同的線程
