I actually think this is a good example of the exception-rule. The function wants to take true or false in "int", and the caller has a pointer. And !!ptr is a shorter and more established way than ptr != NULL to turn non-NULL ness into an int boolean, without having to either repeat or introducing an otherwise unnecessary temporary.
