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。 the linux。 the socke 目錄 摘要 ................................................................................................................................. 1 Abstract ............................................................................................................................ 1 第一章：緒論 ................................................................................................................... 3 什么是網(wǎng)絡(luò)編程 .................................................................................................. 3 優(yōu)點(diǎn) ................................................................................................................... 3 第二章 linux網(wǎng)絡(luò)聊天室設(shè)計(jì)思想 .................................................................................. 4 功能分析 ............................................................................................................ 4 總體設(shè)計(jì) ............................................................................................................ 4 第三章 linux網(wǎng)絡(luò)聊天室工具概述 .................................................................................. 5 GCC ................................................................................................................... 5 GCC 簡介 ................................................................................................... 5 GCC 執(zhí)行過程 ............................................................................................ 5 GCC 基本使用方法 ..................................................................................... 5 GNU Makefile........................................................................................................ 6 Makefile簡介 ........................................................................................... 6 Makefile 規(guī)則 ............................................................................................. 7 GDB 調(diào)試 ............................................................................................................ 7 用 gdb 調(diào)試 GCC 程序 ............................................................................... 7 第四章 關(guān)鍵技術(shù)分析 ...................................................................................................... 8 linux 線程間通信 .................................................................................................. 8 .................................................................................................... 8 .................................................................................................... 8 線程數(shù)據(jù)處理 ............................................................................................ 9 基于 linux 的 socket 網(wǎng)絡(luò)編程 ............................................................................... 9 端口和套接口 ............................................................................................ 9 套接字和套接口地址結(jié) 構(gòu) ........................................................................ 10 基本轉(zhuǎn)換函數(shù) .......................................................................................... 11 socket（）和 bind（）函數(shù) ....................................................................... 12 listen（）和 accept（）函數(shù) ..................................................................... 12 socket 中 TCP 的三次握手建立連接詳解 ..................................................... 13 、 socket 中 TCP 的四次握手釋放連接詳解 ......................................................... 14 第五章 linux下 socket編程實(shí)現(xiàn)過程 ........................................................................... 15 3 聊天室 socket 編譯鏈接過程 .............................................................................. 15 具體操作 .......................................................................................................... 16 參考文獻(xiàn)： .................................................................................................................... 18 附錄 ............................................................................................................................... 18 附錄 A: ............................................................................... 18 附錄 B: ................................................................................. 23 附錄 C: ................................................................................................. 26 附錄 D: ..............................................
