Using an ioctl(). SIOCGIFHWADDR (Get InterFace HardWare ADDRess). If you
look in the source for ifconfig, that should show you how it's done in
more detail, but here's an overview:
First, run through calling access() on the /proc/net entries. Once you
find one which succeeds, create a socket using that protocol (IPX in this
case), and call ioctl(fd,SIOCGIFHWADDR,buffer*).
I'll do a simple implementation later today, if nobody already has one?
"Our attitude with TCP/IP is, `Hey, we'll do it, but don't make a big
system, because we can't fix it if it breaks -- nobody can.'"
"TCP/IP is OK if you've got a little informal club, and it doesn't make
any difference if it takes a while to fix it."
