ethernet address

[Billy Joel]

Does anyone know of a nice, simple C function for finding out
the 48bit ethernet address of the machine you are running the function
on?  I'm looking in all the documentation I can find and can't seem
to find anything that works.  Surely this information is available,
how else do clients boot over the network?  I want to avoid
having the ethernet number in the /etc/ethers file as well.

Thanks in advance
