Thanks Mark.
Very helpful and explains why my other PETSC_NULL_INTEGER uses are still
functioning
and why in some places I have PETSC_NULL_INTEGER(1). I guess I can
replace the latter with PETSC_DEFAULT_INTEGER for a cleaner look.

thanks, that did it. now I am wondering about all the other
PETSC_NULL_INTEGER instances in
my code. how should I be thinking about PETSC_NULL_INTEGER
I would think it's an integer array/pointer in C.
and
PETSC_DEFAULT_INTEGER,
and an integer in C.
so that I know that I am using the correct one?
