smart pointers (boost) explained
...t also comes with such a transfer-of-ownership smart pointer called unique_ptr.
Categorizing smart pointers
scoped_ptr is a smart pointer that is neither transferable nor sharable. It's just usable if you locally need to allocate memory, but be sure it's freed again when it goes out of scope. But...

What is a smart pointer and when should I use one?
...ient smart pointers types, and so you should favour the use of std::unique_ptr, std::shared_ptr and std::weak_ptr.
There was also std::auto_ptr. It was very much like a scoped pointer, except that it also had the "special" dangerous ability to be copied — which also unexpectedly transfers owners...
