Yes, looking for a NULL pointer is a good idea.  I'm
pretty sure I have to pass addresses though.  I tried
passing the actual mpz_t variables, and printing the
memory addresses, but I got copied mpz_ts and not
pointers.  

A better idea than looking for a null is to use a
format string like printf has with conversion
characters for the various GMP types, but I dont need
that for my purposes.
