Echo Server English / 简体中文 English This is a simple echo server written in C, based on epoll event handling, and supports non-blocking IO operations. Getting Started These instructions will help you install and run the project on your local machine for development and testing. Prerequisites ...
跟server端一样,第一步首先要上来创建socket, 3.2.填充sockaddr_in结构 这一步骤也是跟server端一样。 3.3.client要不要bind? 一定要,client也要有自己的IP和PORT。要不要显式[和server一样用bind函数]的bind?不能!不建议!! 如何bind呢?udp client首次发送数据的时候,OS会自己自动随机的给client进行bind ---...

用c 或 c++写网络程序,需要多练习,这次使用poll写一个echo server。 练习要有目标,要能压测,不崩溃。使用通用的压力测试程序,方便和其他小伙伴写的程序对比。在战斗中提升。 走起~ GOGOGO~ 代码 #include<iostream>#include<cstring>#include<sys/socket.h>#include<netinet/in.h>#include<arpa/inet.h>#includ...
选择libuv库里的tcp-echo-server作为源码阅读开头的主要动机是 简单性:回声服务端的功能非常简单,接收客户端发送的数据并原封不动地返回。这种功能的简单性使得代码更易于理解和跟踪。 基础概念:通过实现一个回声服务端,可以学习到libuv类网络通信的基本操作,如套接字(socket)的创建、监听、接受连接请求、读写数据等。
