获取wlan的handle、接口信息Interface Info

WlanOpenHandle
WlanEnumInterfaces

HANDLE hClient = NULL;
DWORD dwMaxClient = 2;
DWORD dwCurVersion = 0;
DWORD dwResult = 0;

PWLAN_INTERFACE_INFO_LIST pIfList = NULL;

dwResult = WlanOpenHandle(dwMaxClient, NULL, &dwCurVersion, &hClient);
if (ERROR_SUCCESS != dwResult)
{
   
   qDebug() << "WlanOpenHandle failed with error:" << dwResult;
   //return false;
}
dwResult = WlanEnumInterfaces(hClient, NULL, &pIfList);
if (ERROR_SUCCESS != dwResult)
{
   
   qDebug() << "WlanEnumInterfaces failed with error" << dwResult;
   //return false;
