Closing an open socket by its fileno

slloyd has asked for the wisdom of the Perl Monks concerning the following question:

Is there a way to close an socket handle if all you have is its fileno? I can open a socket handle as follows but does that actually close it if it was already open?

if(open( $Client, "+<&=$fno" )){
close($Client);
}

Yep, closing that filehandle will cause the descriptor associated with it to close. duff	[reply]

I believe POSIX`::close` should take a file descriptor.	[reply] [d/l]
