why are you using C for URL retrieval? it is a very complex task to perform
in C (definitely not for newbies) and it is completely useless to understand
how the socket api works.
if you want to retrieve an URL from the internet the best choice would
probably be python:
#!/usr/bin/env python
import urllib
(name, header) =
urllib.urlretrieve("http://www.python.org/doc/2.3.4/lib/module-urllib.html";)
or perl with libwww:
#!/usr/bin/perl -w
use LWP::Simple;
$url = 'http://www.python.org/doc/2.3.4/lib/module-urllib.html';
$content = get $url;
die "Couldn't get $url" unless defined $content;
please notice that the examples above are working but not complete.
anyway, i would recommend you to learn how the socket api works in python or
perl before messing with the C socket api, which is much more complex.
