To reply to Graeme :
why not just use the /sbin/ifconfig output ?
Simply to be more dev compliance... using an external program is slower
and sometime ifconfig doesn't exist or is deleted on target computers.

I have these two functions in my .bashrc file. You only need to run
"ii" for the cool output. Now back to the question - If it is for
linux only, why not just use the /sbin/ifconfig output. After all, it
is accurate and seem much easier than all those libc/library methods.

Better, but still Linux only. For a good solution,
a resolver unit that accesses libc should be
written that is portable (unlike the libc unit)
If I understood correctly, the OP had two questions:
1. Retrieve a list of interface names on a *linux* system.
2. Return the IP address for a given *
Many Thanks for this way jeff...
/proc/net/dev is more compatible
Impressed it
for your information.
My program will run only on linux system...

how can i list wich interface loaded without
need to parse /etc/networks/...?
I would parse /proc/net/dev instead
program ifnames;
var
s:shortstring;
f:text;
p:LongInt;
begin
assign(f,'/proc/net/dev');
reset(f);
while not eof(f) do begin
readln(f,s);
p:=pos(':',s);

OK i understand that i using i386 no 64 bits

Note that it is linux/x86 only. No 64-bit, or other platforms.

Many Thanks Jeff and Micha.

Great respects...
Just another question... (this because i came from Windows OS) how can i
list wich interface loaded without need to parse /etc/networks

It doesn't seem like you're using libc specific functions ? You can also
write a fpc 'native' one using fpsocket and f

Please ignore my last post -
This one is a little cleaner...
program ip_addr;
{$MODE OBJFPC}
uses libc;
function GetIPAddressOfInterface( if_name:ansistring):ansistring;
var
ifr : ifreq;

I'm trying to write a function to read the local IP eth0/eth1
using glibc library...
program ip_addr;
{$MODE OBJFPC}
uses libc;
const
IP_NAMESIZE = 16;
type
ipstr = array[0..IP_NAMESIZE-1] of char;
function GetIPAddressOfInterface( if_name:ansistring):ansistring;
var
ifr : ifreq;
tmp:ips
