Description: 建立接收socket,将socket和指定的端口绑定
2、创建接收线程，在线程中调用ioctlsocket()判断是否接收到数据，接收到数据时调用OnReceive()(类似CSocket中的OnReceive())
3、在OnReceive中申请空间调用recvfrom接收数据
4、建立发送socket，和INADDR_ANY绑定
5、调用sendto发送数据
-establishment receiving socket, the socket and designated ports bundled with two to create receive threads, Calling the threads ioctlsocket () to decide whether or not to receive data, to receive information call OnReceive () (similar to the OnReceive CSocket ()) 3, in which the application of space OnReceive call recvfrom four receive data, the establishment of this socket, and INADDR_ANY bundled 5, call sendto send data

Description: 这里是使用说明：
V1.1版修正了二次释放窗口会出错的问题。
运行主程序，先点“开始钩挂”然后在要抓包的游戏或者程序里面按小键盘的星号键呼叫。
然后点“开始”，就可以抓包了，点“停止”是停止抓包，回到游戏点“关闭本窗口”，
在在上面的筐筐里面可以写上保存的文件名，一般是TXT文件，要打完整的路径和名字
否则出错，退出前一定要点“释放本窗口”，不然会出错，然后再点“撤消钩挂”。
再有就是有些游戏会无发呼叫本窗口。
本程序源代码BCB 5.0通过。只用在NT,2000,XP
本程序只钩挂了\"send\",\"sendto\",\"recv\",\"recvfrom\"这4个函数，WSAsend等不钩挂，
因为是用API钩子写的抓包程序，而且小弟也是菜鸟，难免有BUG。源代码可以任意修改和发布。
你改得好的话请给我一份。小弟感激不尽。

Description: 服务客户端拿易写的
DLL是C++写的 拿易完全可以写 只是那时候刚学C++就拿来练手了
这个最多实现5个人对战 （人品差 测试的时候加我一共就找到3人...）
主要hook 4个函数：
sendto函数 （发送房间信息）
WSARecvFrom函数 （接受房间信息）
connect函数 （连接玩家）
GetAcceptExSockaddrs函数 （得到玩家地址|多人对战关键）
里面大部分源码都来自易友开源
结语：
凌晨孤星的APIHOOK很强大
