Difference between boost::scoped_ptr and std::unique_ptr

Question

Is the sole difference between boost::scoped_ptr and std::unique_ptr the fact that std::unique_ptr has move

Answer 1

unique_ptr owns an object exclusively.It is non-copyable but supports transfer-of-ownership. It was introduced as replacement for the now deprecated auto_ptr.

scoped_ptr is neither copyable nor movable. It is the preferred choice when you want to make sure pointers are deleted when going out of scope.
