Hi monks,
I have two simple scripts, a TCP server and a TCP client. My server sends the client a random word (e.g Hello) upon EVERY CONNECTION...
So my client has a for loop that connects to the server 10 times and requests a new word. After the seventh connection, everything stops working, and I get an error:
"Use of uninitialized value $word in concatenation (.)"
Here is my code:
[...]
for (my $i = 0; $i < 10; $i++) {
$socket->recv(my $word, 1024);
print "Your new word is: $word\n";
}
[...]
I am using warnings and strict in my code.
Do I need the IO::Socket::INET in the for loop, or, whats happening? :(
NOTE: $socket is also declared in the first scope of code
