The idea of static methods in C++ is based on having methods that are independent of member variables, so since static methods shouldn't be tied to member variables, there's really no such thing as a static destructor.

A more accurate description would be:
The idea of static methods in C++ is based on having methods that are independent of CLASS INSTANCES, so since static methods shouldn't be tied to AN INSTANCE, there's really no such thing as a static destructor.

Although you are correct, member variables cannot be used without an instance.

You are right Andrew... :)

A more general OO terminology would be Class Methods and Instance Methods. In C++ the class methods are declared with the keyword static, with the only exception being constructors. A member variable is an unspecific term. You can use a class variable without an instance, while an instance variable requires an, well... instance.

Solution 2

The nearest thing to a "static" destructor would be something like a singleton combined with an object manager - as implemented in ACE - see: ACE__Singleton[^]. This, or something like it, is what people usually are looking for when they think about "c++ static destructor"[^] .

Sure, 5. I was trying to imagine a possible meaning of "static destructor"... Ha-ha!
