if(defined($mgr_sock)) would evaluate to false. That's all you need to do with the plain vanilla blocking I/O you're using now.<br>
<br>
Down the road, if non-blocking I/O is set, there are other strategies. The traditional way was an ioctl() FIONREAD that returned 0 for the bytes value, though the ioctl() call did not fail:<br>
<br>
require 'sys/<a href="http://ioctl.ph" target="_blank">ioctl.ph</a>';<br>
<br>
...<br>
<br>
my $bytes_waiting = pack("L", 0);<br>
<br>
ioctl($mgr_sock, FIONREAD(), $bytes_wating);<br>
<br>
$bytes_waiting = unpack("L", $bytes_waiting);<br>
<br>
if($bytes_waiting == 0) {<br>
# Far-end disconnected.<br>
<br>
close($mgr_sock);<br>
return;<div><div></div><div class="h5"><br>
