Hi,
Doing a tcp4u_connect will attempt to open a socket on the specified=20
server, on the specified port. A program needs to be running on that
server, waiting on the specified port for a connection to be achieved.
Using sockets always involves at least two programs, they don't =
necessarily
have to both be your programs. You could for instance connect to a =
telnet=20
port on a Unix server, or a SMTP port on a mail server etc.
The example programs that come with tcp4u all happen to have a server
side and a client side.
It's a little difficult to determine what is wrong with the information =
you gave.
If you want to send me your program and a little information on what =
it's=20
supposed to do I'll gladly take a look at it.

I'm using tcp4u currently, but there seems to be a problem. I CAN'T =
GET IT TO CONNECT. ARG. It's driving me crazy. Right now, I'm pretty =
much copying and pasting statements, and modifying them as need be. I'm =
100% sure the syntax is correct. So, I was scurininzing tcp4u_connect in =
manual.html, and something caught my eye. It said it connects to sockets =
doing a tcp4u_accept. Now, I really hope this isn't true, but does this =
only work with server specifically doing a tcp4u_accept, or all server =
just generally accepting connections?
=20
=20
Btw, for reference, here is the statement I'm using:
sock_connect =3D tcp4u_connect(server_name, NULL, port)
=20
No problem as far as I can tell. I have narrowed it down to this =
statement using trace.
=20
May try my hand at libnet if this doesn't work. I really like tcp4u =
though.
