This is a continuation of my previous question, which was rather large so I decided to just post the specific part I have a question about. Here's a trivial example of what I'm doing. What I would like to do is have the child open the FH reference, which would also maintain the same state (i.e. open) in the parent. But it is not happening. The reference seems lost. Is there a way to make the FH state the same in both parent and child? 
use strict;
use warnings;
use Scalar::Util 'openhandle';

my $fh_ref = \*FH;

my $pid1 = fork();

if ($pid1) # parent
{
    sleep 1;

    print "parent : ";
    print openhandle($fh_ref) ? "yes" : "no";
    print "\n";

    print FH "line 3\n";
    print FH "line 2\n";
    close FH;

    exit;
}

# Child from here on.
open_fh($fh_ref);

print "child : ";
print openhandle($fh_ref) ? "yes" : "no";
print "\n";

#exit;




sub open_fh
{
    my $_fh_ref = shift;
    open($_fh_ref, "|sort") or die $!;
}

Output: 
child : yes
parent : no
print() on unopened filehandle FH at fork_fh.pl line 17.
print() on unopened filehandle FH at fork_fh.pl line 18.
