Getting local IP / MAC address

Hi,

Possibly this is not the best list to ask, but still, would appreciate
if some one could help.

Is there any portable / standard way to get the local IP & MAC address
in a C program (in user space)? I heard ioctl "SIOCGIFADDR" is a way,
but is is portable (read dependable)?

Also would it provide me only IP address. Any way of getting MAC address?

Thanks,

Dan

well you speak as if there is one, but of course there can be many! Most
likely you'll find at least 2, probably more.

if you look at the ifconfig program, which is written in C, it gives you
this information. So I suggest that you look at the sourcecode for this
program to see how that program does it...
