Hi Monks,

Given the following code: 
my %h;
my $data_db = "data_db";

tie (%h, 'DB_File', "$data_db") or die $!;

if (not exists($h{$id})) {
  $h{$id} = 'some value';
}
untie %h;

How can I use 'flock' to prevent the database file from being called when it's being processed?

Thanks in anticipation :)
