For guidelines on using owning and access pointers or smart pointers, please see the how to use pointers correctly page.
Owning pointers, or smart pointers, are pointers that retain knowledge of how many live pointers there are to their contained object. This has two purposes. First, the pointed-to object won't be deleted unless all owning pointers are deleted (preventing segfaults). Second, the pointed-to object will be deleted automatically if all owning pointers to it are deleted (preventing memory leaks).
This page once hosted documentation on Rosetta's deprecated ReferenceCount based smart pointer system.
