Newbie Question, please help with searching

Hi,
This is a very basic problem I'm sure, but one which has been annoying the
hell out of me.
I'm trying to write a simple piece of C code which will pull the remote IP
address out of Sendmail Received: headers.
So all I would need to start is an example of how to, open a specifified
file (with fopen i guess), search it for a regular expression (something
like "%s.%s.%s.%s" (i know that's probably wrong, but the idea is to look
for IP numbers))
and then print the match to the screen, or exit saying "No match."

I do have a Perl version of the above program if that would be helpful to
anyone, but to me, perl makes less sense than C.

Anyway I'd appreciate any help, and say thanks in advance.
