Is stack-only variable possible in C++?

Question

Currently I want to make wrapper accessor class in multithreaded environment. The purpose of the class is simple - Grab a lock on its construction and release a lock on its destruction. Other than that, it's identical to a normal pointer. Moreover, I want to prevent it from being created on heap area to ensure that the lock will be released eventually.

The inverse is fairly easy (private constructor with factory method), but I don't know that a stack-only variable is possible. Is there anyway?

Answer 1

Well, what about you overload operator new for your class and delcare it private?
