[fpc-pascal] RE: Get Local IP using glib (eth0,eth1)

[TOUZEAU DAVID]

Many thanks to the community

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.

To reply to Marco :
And the only "good" solution is a portable resolver unit?
How will you resolve "eth0" on Win32 or BSD ?

For WIN32, i d'ont care because the program is only for Linux systems.
Your are true, in BSD the network interface is not the same and i must 
detect wich interface is used...

Best regards
