WebFor non-concrete types, such as types in an inheritance hierarchy, return the object by unique_ptr or shared_ptr. If a type is expensive to move (e.g., array), consider allocating it on the free store and return a handle (e.g., unique_ptr), or passing it in a reference to non-const target object to fill (to be used as an out-parameter).

WebJul 2, 2024 · When it comes to partial internal synchronization, shared_ptr serves as a good example. Since the reference counter is a shared variable, it needs to be protected when concurrent write occurs. It is not possible for the calling code to know that. So shared_ptr protect the reference count in its implementation.

Webshared_ptr is a minimal implementation of smart pointer, a subset of the C++11 std::shared_ptr or boost::shared_ptr.
