ANSI C How to get name server (DNS) address in linux?

Question

I want to use in my code local DNS addresses and am looking for a library that would produce it. Is there anything like it or do I have to parse /etc/resolv.conf myself?

Thanks

You can use the resolver functions as described in the answer to this question or read the addresses of name servers from the file /etc/resolv.conf which is a simple text file, such as

# Generated by NetworkManager
nameserver x.x.x.x
nameserver y.y.y.y

where x.x.x.x and y.y.y.y are ip addresses.

Thanks for pointing me in the right direction. I Finally used the links you provided plus functions described [here](http://beej.us/guide/bgnet/output/html/multipage/inet_ntopman.html). – R3v3r3nD May 24 '11 at 05:51
