Question

使用C/C++语言如何获取笔记本的无线网卡mac地址？

我自己已经实现了一个获取PC MAC地址的接口， 现在的问题就是无法获取连接无线网络的机器的MAC，我希望在回答中突出如何获取无线网卡MAC地址，谢谢

Answer 1

#include<stdlib.h>

int main()
{
char cmd[15] = "ipconfig /all";
system(cmd);
system("pause");
}

显示界面中，找到无线网卡，其中物理地址（physical address）显示的就是无线网卡的MAC。

追问

您能够补充一下获取无线网卡MAC地址的代码吗？ 上面的代码可以获取MAC地址，但是对我没用，不过还是谢谢您
