[Winpcap-users] How to get local MAC address ?

[MARMONIER Cédric]

Thanks but there is a probleme.
GetAdaptersAddresses() don't give me the same adapter list that pcap_findalldevs()

If I have :
IP_ADAPTER_INFO *adapter_Iphlpapi = NULL;
pcap_if_t *adapter_WinPCAP = NULL;
adapter_Iphlpapi = getMyAdapter(); // use the GetAdaptersAddresses function to select an adapter

=> How can I do to set the good adapter in the adapter_WinPCAP variable ?


Is there a method which can operate with Windows Xp (and Windows 7 if possible) and Linux ?

David is correct.

GetAdaptersInfo is obsolete since Windows XP and people should use
GetAdaptersAddresses now.

The field 'PhysicalAddress' and 'PhysicalAddressLength' in the
'IP_ADAPTER_ADDRESSES' struct correspond to the MAC address of the
device. The 'PhysicalAddressLength' value should equal to 6 for
Ethernet adapters.

more info.:)
