Personally, I'd make the NULL_PTR error message a bit more specific. "Memory Error" is quite general. The real issue is that specific invalid arguments were passed in. Now since this may live in it's own module and not be a public function, that could be fine. But if it's ever expanded, you'll want callers to know what specifically went wrong to help debugging.
