I am looking to save some time when going through a large data structure, mainly I would like to have the recursive call go through c, rather than perl.

Here is an example sub that I'm using: 
# object1:
sub depth{
    my $self = shift;
    my $max = 0;
    foreach my $item (0 .. 15){
        if(defined($self->{child}->[$item])){
            my $temp = $self->{child}->[$item]->depth; 
            if($temp > $max){
                $max = $temp;
            }
        }
    }
    $self->{myDepth} = $max+1;
    return $max+1;
}

# object2
sub depth{1}

Now there is a base case, a child can be an object 1 or 2, but an object 2 has no children.

My question is how would this best be impmented through inline c, if it is possible. Nothing I've read on inline c has the complexity of recursion, and I do not know what $self looks like in c (do the refs to the same type of object become pointers, or what?)
