先上代码；

代码是用Winpcap获取本机网卡列表；
开发环境是Win10；VC++ 6.0；
先要安装Winpcap的驱动和DLL；如果安装了Wireshark封包捕获工具，则Winpcap已经安装好；没有的话单独下载安装；
再下载Winpcap开发包，解压至某个目录；
编译程序要把Windows.h 注释掉；否则系统自带的Winsock2.h 和 Winpcap的头文件中定义的宏有冲突；一堆错误；
第一次运行，没有发现网卡；需要开启NPF服务；
获取到本机有8个网卡；
打开Wireshark软件看一下；Wireshark也获取到本机有8个网卡；其中包含一个VMWare虚拟机上的；
后面几个图是，添加包含文件路径，库文件路径，lib文件也要加到lib文件列表；
为了使用Winpcap的远程访问，必须在预处理器中加入HAVE_REMOTE；
