to be more precise. Here is the code of a sub 

sub interface_control {
        my $s           = shift;
        my (@r, $v, @h);
        $s->get_handles(rtrs=>\@r, vars=>\$v, hosts=>\@h);

[download]

get_handles returns the handle for the args specified. These args are stored as hash/key pair in a file

Call to the sub is made via interface_control($s)

MY question is , i want to specifically access, one of the element in the array @r, say only $r[0]. Is there a way to access this or pass any reference to interface_control call
