TCP网络编程基础步骤

server
sockfd = socket(AF_INET,SOCK_STREAM,0);
struct sockaddr_in ser_addr,cli_addr;
ser_addr.sin_family = AF_INET;
ser_addr.sin_addr.s_addr = htonl(INADDR_ANY);//这里使用 INADDR_ANY，服务器将在所有可用的IP地址上监听连接。
ser_addr.sin_port = htons(11000);
ser_len = sizeof(ser_addr);
ret = bind (sockfd,(sockaddr *)&ser_addr,ser_len);
if(ret<0){
	perror("bind fail");
	return -1;
}
ret = listen(ser_sockfd,5);
if(ret<0){
	peeror("listen");
	return -1;
}
cli_len = sizeof(cli_addr);
accept(ser_sockfd,(sockaddr *)&cli_addr,&cli_len);
