What would be a do nothing operator for a function returning void?

I want to return nothing inside a function returning void. How would I do that?

You can do one of two things:

  1. Structure the flow of the code so that there is no need for a return statement.
  2. Place return; statements where you want the function to return control to the caller.

EDIT: To clarify, return; is a statement that returns control to the caller without yielding a value.

That's basically it.
