low level Internet
Greetings,
I've been away from the list for about nine months because I was then
transitioning my e-mail (and many other things). I'm now a freshman at the
U of Illinois Urbana studying computer science (Java and in the future C).
Anyway, I'm interested in writing a program that will communicate using
TCP/IP in a rather low level way. The library will have about three main
routines.
integer ConnectionID = function OpenConnection(string serverIP, integer
port)
object result = function communicate(connectionID, string to send)
procedure CloseConnection(ConnectionID)
With some knowledge in (just ordinary text) protocol commands (FTP, POP3,
SMTP, maybe even HTTP), geeks can use this library to do interesting things.
I looked at some EU programs that use the Internet, like EuFTP and Web
Shepherd. I think I can do the first procedure above using Wininet.dll and
"InternetConnectA", I just need to study all the API parameters (a chore
since I don't know C yet, but a definable one). I can probably trivially
"close" the connection.
That leaves the second procedure. All the commands in the above mentioned
programs link libraries to wininet.dll (I think like "GetFileA") and such.
Does anyone know how to do what I am proposing? I would appreciate any
advice. Thank you.
Alan
