Subject: Simple socket/telnet library?

I would like to write an extremely simple and brain-dead Web
browser for as part of an HTTP server benchmark. Is there a library
of C routines someone has already put together that allows one to open
a connection to a host at a specific port and then send/receive text?
My knowledge of UNIX socket and TCP/IP programming is exactly zero. :(
For example:
char *gethtml(char *hostname, int port, char *request, int bytes)
{
int *open_socket;
char *html;
html = (char *)(malloc(bytes));
if(!(open_socket=tcpopen(hostname, port)))
{
fprintf(stderr, "Could not connect to host!\n");
exit(1);
}
tcpwrite(open_socket, request);
tcpread(open_socket, html, bytes);
tcpclose(open_socket);
return(html);
}
Right now I'm forking off a "lynx -source -dump" process for each
request, which gets expensive when you have ten or more of these
things going on one machine. If there is a ready-made library with
functions akin to tcpopen(), tcpwrite(), tcpread() and tcpclose() that
works with a 4.4BSD system (FreeBSD 2.0, in my case), that would be
fantastic. Source code fragments, tutorial files, primers, etc. also
gratefully accepted. Thanks.
BTW, is it possible to create a special file that is connected to
a host at a particular port, and be able to do something like "echo
'expn somealias' > special-file" and then "cat special-file" to read
from the socket?
