I am using a thread to open a file handle, and would like to pass control of that file handle to a different thread. Unfortunatley it doesn't seem like I can close a file handle in a different thread then which it was opened.

I'm using Perl 5.8.0 and have now switched to ithreads.

Does anyone have any ideas?

#!/usr/bin/perl

use threads;

$filename = "/tmp/input.log";
$outputdir = "/var/log/";
$first_event = 1;
$position = 0;
$time = time();

# Define Timer
sub timer {
        my $counter = 0;
        while (1) {
                sleep(1);
                if ($counter >= 60) {
                        $counter = 0;
                        #
                        #I can't seem to close FILE from the main thre
+ad... why?
                        #
                        close (FILE);
                        $outputfile = $outputdir . "log-". time();
                        open(FILE, "> $outputfile") || die("Can't open
+ $outputfile to write to");
                }
                $counter++;
        }
}

$thr1 = threads->new(\&timer); # Spawn the thread

open(TAIL, "tail --follow=name $filename|");
$outputfile = $outputdir . "log-". time();
open(FILE, "> $outputfile") || die("Can't open $outputfile to write to
+");
while (<TAIL>) {
        # do some stuff and print to FILE
}
