I stand corrected.
However, the reference I pointed at was ALSO a way to acquire the MAC address of an interface.
Additionally since the question was asked in the context of WinPcap, it might be relevant to someone using WinPcap's API's.

Linux returns MAC address info in the results returned with pcap_findalldevs().
There once was some discussion about adding this functionality to WinPcap's implementation of pcap_findalldevs(). It never came to anything since it fell off the radar of the developers, and it wasn't a significantly pressing requirement.
For now you can either use the API David points at, or you can use something derived from Gianluca's developer pack example.
