If I read what you wrote correctly, you want to pass a filename to a sub in another module and then later, be able to read the file one line at a time, right? If so, I think this might work:

package Foo;
use strict;

my $sep;

sub set_file {
    my $file = shift;
    $sep = shift || "\n";
    open FH, "< $file" or die "Cannot open $file for reading: $!";
}

sub get_line {
    local $/ = $sep;
    my $temp = <FH>;
    return $temp;
}

1;

In your main program:

use strict;
use Foo;

Foo::set_file( $some_file );

for ( 0..10 ) {
    print Foo::get_line 
};

If that's not what you're looking for, let us know. It seems to me that seek is not what you're needing here.
