This worked great. I had to tweak it a *little* bit because I'm
after a slightly different thing, but I am now happily printing data from
the client to STDOUT (and understanding how that works, too).
BTW, this TCP/IP server is a test tool for some brokerage software.
A few more lines of code and I'll be impersonating the New York Stock
Exchange!

Subject: RE: basic question: handling input to TCP/IP server
Something like this worked for me in the past:
use strict;
use IO::Socket::INET;
my $sock = IO::Socket::INET(....);
while(1) {
my $output;
my $n = sysread($sock,$output,1000);
last if(!defined($n));
print STDOUT $output;
}
And using syswrite() for writing.
perldoc -f sysread
perldoc -f syswrite

Subject: basic question: handling input to TCP/IP server
Hello all...
I've implemented the TCP/IP server at the top of p.441 of The Camel (3rd
edition) Chapter 16, and it's working fine. That is, it opens the port I
tell it to, and other processes connect to it and happily send it stuff.
(This is using IO::Socket::INET).
But now I'm a little confused about how to handle I/O over the TCP/IP
connection. The first thing I'd like to do is to print incoming data to
STDOUT. It seems that I have to manipulate the "accept()" statement, and I
probably have to use the angle operators, but I'm struggling to truly
understand what's going on here in order to get the syntax correct. (I
figure if I can get a handle on manipulating the input, output will be
easy.)
I'm continuing to hack at this, but any pointers to (simple!) TCP/IP
server behavior to speed me on my way would be welcome.
Thanks,
-Chris
