说明：  Socket 编程让你沮丧吗？从man pages中很难得到有用的信息吗？你想跟上时代去编Internet相关的程序，但是为你在调用 connect() 前的bind() 的结构而不知所措？等等… 好在我已经将这些事完成了，我将和所有人共享我的知识了。如果你了解 C 语言并想穿过网络编程的沼泽，那么你来对地方了。
(Socket Programming let you frustrated? From the man pages, it is very difficult to get useful information? Times you want to go to the provision of Internet-related procedures, But as you call connect () before the bind () and the structure of a loss? And so on ... Fortunately, I have these things accomplished, and I will share all the knowledge I had. If you know the C language and would like to network programming through the swamp, then you come to the right place.)
