I just discovered seekdir, and its kinda broken on win32 (not that I'm 100% sure of how its supposed to behave )

5.006001 seems to behave the most as I expect based on my knowledge of seek

I'm using ActivePerl/mingw-perl on WinXP 

#!/usr/bin/perl --
use strict; use warnings;
use Data::Dumper;
use File::Temp qw/ tempdir /;

print $], "\n";

my $dir = tempdir;
chdir $dir or die $!;
touch( qw/ hi.txt there.txt you.txt / );



opendir my($d), $dir or die $!;
foreach my $ix (-1 .. 6) {
    printf "seekdir(%3d) =  %d => %s\n", 
        $ix,
        seekdir($d, $ix),
        DD( [ readdir $d ] );
}
print '#' x 33,"\n";
sub DD { scalar Data::Dumper->new([@_])->Indent(0)->Useqq(1)->Dump ; }
sub touch {
    for my $file ( @_ ){
        open my($fh), '>', $file or die $!;
        close $fh;
    }
}
__END__
