1、1初始化一个socket2建立一个socket列表用于管理socket3将初步连接的socket放入列表中4用select判断列表中未处理的socketWinAPI版本1.USHORTnPort=4567;//此服务器监听的端口号//创建监听套节字SOCKETsListen=::socket(AF_INET,SOCK_STREAM,IPPROTO_TCP);sockaddr_insin;sin.sin_family=AF_INET;sin.sin_port=htons(nPort);sin.sin_a

2、ddr.S_un.S_addr=INADDR_ANY;//绑定套节字到本地机器if(::bind(sListen,(sockaddr*)&sin,sizeof(sin))==SOCKET_ERROR){printf("Failedbind()");return-1;}//进入监听模式::listen(sListen,5);2.//select模型处理过程//1）初始化一个套节字集合fdSocket，添加监听套节字句柄到这个集合fd_setfdSocket;//所有可用套节字集合FD_ZERO(&f
