(C++) boost::weak_ptr

boost::weak_ptr is a Boost smart pointer class that 'stores a "weak reference" to an object that's already managed by a shared_ptr..' [1].

boost::weak_ptr can be used to obtain a read-only pointer from a boost::shared_ptr that detects if the original boost::shared_ptr still exists.
