服务器端通过socket()系统调用创建一个Socket数组后(即设定了接受连接客户的最大数目)，与指定的本地端口绑定bind()，就可以在端口进行侦听listen()。如果有客户端连接请求，则在数组中选择一个空Socket，将客户端地址赋给这个Socket。然后登录成功的客户就可以在服务器上聊天了。-Server-side through the socket () system call to create a Socket after the array (that is set to receive the maximum number of connected customers), with a specified local port to bind bind (), will be able to listen on port listen ().
