look at the code.
I compare it with the example program words by words.
and I have tried -lsocket -lsnl in linking.
(of course, the system says there is no such file or directory.
BTW, all the socket and bind are system calles. need to link
socket library?)
does not work at all.
I typed the error message, it says: the address is already
in use.
following is the code. thanks a lot!!

So the answer is very clear: address is already in use. Try to bind a free
port.

Try 4000. 80 is used for system, usually is http.

try telnet to that port you are trying to bind, and see whether you get
a Connection refused error.

I tried.
error msg:
Could not open a connection to host on port 80 :
Connect failed
whatis the meaning? the port is not in used at all, right?
