Edit Question
Title
Body
Is there some equivalent class for C++1x's std::unique_ptr in the boost libraries? The behavior I'm looking for is being able to have an exception-safe factory function, like so... std::unique_ptr<Base> create_base() { return std::unique_ptr<Base>(new Derived); } void some_other_function() { std::unique_ptr<Base> b = create_base(); // Do some stuff with b that may or may not throw an exception... // Now b is destructed automagically. } EDIT: Right now, I'm using this hack, which seems like the best I can get at this point... Base* create_base() { return new Derived; } void some_other_function() { boost::scoped_ptr<Base> b = create_base(); // Do some stuff with b that may or may not throw an exception... // Now b is deleted automagically. }
