</blockquote></div><br><div>It's superfluous for the same reason we don't "set" by passing "const PetscInt". The const is irrelevant to the caller. All it means is that the implementation doesn't change the *its* copy (pass by value) and even that isn't type checked with respect to the public declaration. It's just clutter and suggests that the person who wrote it doesn't understand types.</div>
