API for identifying the DHCP server's IP address.

Hi all,

Here we are writing an application, which basically shows the network
configuration parameters of our linux box.
A dhcp client is working which fetches the ip address from the DHCP
server operating in our network. There could be morethan one server
operating. This application also needs to display the DHCP server's IP
address the one that assigned an IP address to our box?
How can our application program identify the DHCP server's IP address?
Any specific API or IOCTL for this purpose?
Please suggest.

Thanks,
Lawrie.

scan file /etc/dhcpc/dhcpc-d-ethx.info for
'DHCPSID=x.x.x.x' That should be the server IP that gave
you your address.
Sys V filesystem may hide elswhere, or add a line of code to the dhcp
client software to write a log file of the server IP when it gets one,
perhaps in the /proc folder
