If I have the following hash: my %hash=(a=>1,b=>2); I can initialize/clear out the hash by doing: %hash=(); So if I pass a hash to a sub as a reference, is there a way to initialize/clear the hash using the reference? 
my %hash=(a=>1,b=>2);
my $x=&foo(\%hash);

sub foo{
    my $h=shift; #hash reference
    #I want to clear out the hash here...
    $h->{c}=5;
    return 1;
    }
