Well, authenticating is not much to add. Just send some more options to
libcurl.

I'm guessing here that you're talking about using HTTP to verify that the
requested file is present?

In that case, make sure that the return code specified in the reply-headers
is 200 when you make a HEAD on the file. There are several ways to check
that, but curl_getinfo() is certainly an easy way.

You write the body part to the file, you need to check that file for whatever
it is you want to find.

It is impossible for me to say based on this absense of information, but I
would say that in general that is a good idea.
