For C++, 0 is supposed to be preferred over NULL. For varargs,  
though, the compiler might not know your intent. I've seen places  
that state modern compliers treat NULL as exactly 0 (in which case  
static_cast<void*>(0) should do the trick), however you should  
probably check on a C++ newsgroup for details.
