c++ - auto_ptr or shared_ptr - in c++03 environment, utilize auto_ptr or (boost) shared_ptr homecoming resource function? (where in c++11 1 naturally utilize unique_ptr .) auto_ptr<t> f() { ... homecoming new t(); } or shared_ptr<t> f() { ... homecoming new t(); } auto_ptr has quite pitfalls (not to the lowest degree it's construction awfully buggy on msvc 2005 have use), shared_ptr seems overkill ... in c++03, utilize either bare pointer or auto_ptr , allow caller decide on ownership strategy. note 1 of pitfalls of smart pointers covariance not apply them, meaning can override base* f() derived* f() cannot override std::x_ptr<base> f() std::x_ptr<derived> f() ; , in case have no selection utilize simple pointer. c++ shared-ptr auto-ptr visual-c++-2005
