怎样获得本机所有网卡的信息啊？有api函数吗？
怎样获得本机所有网卡的信息啊？有api函数吗？

------解决方案--------------------
IPHELPER GetAdapterInfo()
------解决方案--------------------
struct hostent *hp;

gethostname(LocalName,128);
hp = gethostbyname(LocalName);

for(int i=0; hp!=NULL && hp->h_addr_list[i]!=NULL; i++)
{
.....
//inet_ntoa(*(struct in_addr *)hp->h_addr_list[i])可以得到第i个网卡的IP地址.

}

hp里存着你所有网卡的信息.你挨个处理吧
------解决方案--------------------
我觉得这个问题去下载个cnpacks比较好。里面有详细的吧。
