const void * NULL = 0; Then, the C++ NULL constant is a true pointer with a value of 0. const int NULL = 0 is somewhat problematical in a 64-bit environment, since pointers are 64-bits. But, since C++ is fully prototyped, it will be widened appropriately.
Not on stdarg variable argument lists, if the underlying function expects
a pointer.
