Returns a bit field representing all block attributes set for the memory referenced by p. If p references memory not originally allocated by this garbage collector, points to the interior of a memory block, or if p is null, zero will be returned.
A pointer to the root of a valid memory block or to null.
A bit field containing any bits set for the memory block referenced by p or zero on error.
