Does the called function need to update the variables or only extract
their value. If the latter, then simply passing the variable
(actually its value) as an argument in the calling statement seems
sufficient. If the former, then pass the address of the variable to
the function and dereference the address as needed.
Are you trying to do something that makes these techniques unworkable?
