	You shouldn't need to cast NULL, I don't think...  

	Either way, even better than that would be:
	if (NULL == my_pointer) ...
	since this will give you a compiler error if you make a typo and 
only use one equal sign.  (Otherwise, it is an assignment, which can 
cause no end of problems.  It's also a PAIN to find, when you do do it.)
