Actually, many consider the preferred way to write this

	if (key->both.ptr) {

instead, since the condition you want to check is 'is key->both.ptr
a valid pointer', not 'is key->both.ptr inequal to the invalid
pointer'. The normal use for NULL is only in assignments and 
initializations, not in comparisons.
