That's not really a good idea. You could just set timeout option on the socket after creating it:

use Socket qw(SO_RCVTIMEO);
use POSIX qw(:errno_h);
...;
my $timeout = pack 'L!L!', $sec, $usec;
$handle->sockopt(SO_RCVTIMEO, $timeout);
...;
my $res = $handle->recv(...);
unless(defined $res) {
    if($! == EAGAIN or $! == EWOULDBLOCK) {
        say "time out";
    }
}

Does the Timeout parameter to IO::Socket::INET->new() have the same effect as the sockopt() method?

Maybe another WTDI.

Not really, despite documentation for IO::Socket::INET says "Timeout value for various operations", Timeout parameter is only used by connect method of IO::Socket, it doesn't affect recv in any way.

Huh! Good to know. Thank you zwon++
