And note that because the argument is untyped (it is an elipsis
argument) you cannot use the normal C++ 0 as a synonym for NULL.

You must either use NULL explicitly or, if you want something more C++
like, cast to void* with static_cast<void*>(0).  Otherwise on 64 bit
systems the 0 will be treated as a 32 bit integer rather than a 64 bit
pointer.
