Hello Monks,

How can I share among threads a FileHandle to Write ? 

#!/opt/coolstack/bin/perl  -w
use strict;
use threads;
use threads::shared;
use FileHandle;

my $nthreads = 64;
my $x : shared; # For sync
my $fh = FileHandle->new("> out.txt");

my @thrs;

for(1..$nthreads){
  print "START $_ \n";
  my ($thr) =  threads->create(\&worker, $_, $fh);
  push @thrs ,$thr;
}


$_->join for @thrs;

print "STOP: " . localtime() . "\n";

$fh->close;

print `wc -l out.txt`;

exit;

#----------------------------------------------------
sub worker{
  my $id = shift;
  my $fh = shift; 
  my $tmp;


  for(1..1000){
    lock $x;
    print $fh "bla blalbla bla blal bla bla bla bla\n" ; #NOT SHARED!!
+!!
  }

  print "$id>LOAD EXIT\n";
}
