This example shows you how to use the NetBIOS API to retrieve

the MAC addresses of the network adapters in a system.

There are two weaknesses to this approach. The first is that

you have to have NetBIOS installed, which implies Windows file/print sharing.

The second is that if you have more than one network adapter,

you may have to do extra work to figure out which address you really want.

If these weaknesses are a problem, you might look at the RPC variation

for getting the MAC address.
