unblocking sockets

[pmg]

I need to write an application on Linux and Windows which uses lots of unblocked sockets. I am using ActiveState for Windows.

I would prefer to use IO::All because it looks really cool, so can I how do I set non-blocking mode there.

If IO::All is not suitable, what is the best way of setting unblocking mode.

Thanks

This example comes from perldoc -f fcntl:

use Fcntl qw(F_GETFL F_SETFL O_NONBLOCK);

$flags = fcntl(REMOTE, F_GETFL, 0)
    or die "Can't get flags for the socket: $!\n";

$flags = fcntl(REMOTE, F_SETFL, $flags | O_NONBLOCK)
    or die "Can't set flags for the socket: $!\n";

REMOTE there is the socket handle. You may need to dereference if you have a lexical handle ( *{$sock) ).

Check out Event::Lib, which is a wrapper around libevent. This will really make your non-blocking IO programming a breeze.
