Flag a parameter of a smart pointer sort (a sort that overloads operator-> or operator*) which is copyable/movable but by no means copied/moved from in the function overall body, and that's never ever modified, and that is not handed alongside to another purpose that could achieve this. Meaning the ownership semantics aren't made use of.
Except you might be composing the bottom degree code manipulating hardware straight, consider volatile an esoteric feature that is definitely greatest prevented.
Here's a way to shift a pointer with no check (picture it as code in the implementation a shift assignment):
