qt4 - 在Qt的Windows上获取MAC地址

我正在尝试使用以下代码在Windows XP上获取Mac地址:

QString getMacAddress()
{
QString macaddress="??:??:??:??:??:??";
#ifdef Q_WS_WIN
PIP_ADAPTER_INFO pinfo=NULL;

unsigned long len=0;
unsigned long nError;

if (pinfo!=NULL)
delete (pinfo);

nError  =   GetAdaptersInfo(pinfo,&len);    //Have to do it 2 times?

if(nError != 0)
{
pinfo= (PIP_ADAPTER_INFO)malloc(len);
nError  =   GetAdaptersInfo(pinfo,&len);
}

if(nError == 0)
macaddress.sprintf("%02X:%02X:%02X:%02X:%02X:%02X",pinfo->Address[0],pinfo->Address[1],pinfo->Address[2],pinfo->Address[3],pinfo->Address[4],pinfo->Address[5]);
#endif
return macaddress;
}

建议代码在这里:http://www.qtforum.org/post/42589/how-to-obtain-mac-address.html#post42589

我应该包括哪些库才能使其正常工作？

最佳答案

使用Qt和QtNetwork模块，您可以获取如下所示的MAC地址之一:

QString getMacAddress()
{
    foreach(QNetworkInterface netInterface, QNetworkInterface::allInterfaces())
    {
        // Return only the first non-loopback MAC Address
        if (!(netInterface.flags() & QNetworkInterface::IsLoopBack))
            return netInterface.hardwareAddress();
    }
    return QString();
}
