【Visual C++】：在win平台发原始数据包实例(源程序)在win平台发原始数据包实例(源程序)

前几天受一个朋友相托从unix移植一个程序到windows而源程序使用了RAW_SOCKET
故只能用Libnet for nt改写
源程序如下:(改写后的程序令付)

编译前须先下载libnet NT ftp://202.117.82.4
其自带一个tcpspoof的程序,编译参数和其一致但增加wsock32.lib
并添加定义
struct timeval {
long tv_sec; /* seconds */
long tv_usec; /* and microseconds */
};
