     I need to compare these internal variables to other variables,
     so what is the best way? 

To answer that question I have to ask what you mean by "compare" in
this context.  In other words what are the `value semantics' for the
comparison.

If you just want to check if a pointer to a variable points to the
same variable as another, then "if (v1 == v2)" will do the job.
But I'm not sure if that's what you want.
