smart_ptr is a smart pointer policy class that can use different ownership logic and semantic polices, which allows the developer to get the best performance and/or interface for a particular requirement.
The smart_ptr class can be used with STL containers to create containers of smart pointers, moreover it can be used to create a container of abstract based objects via smart_ptr. In general, smart_ptr is faster than boost::shared_ptr. When used with STL containers, the smart pointer is faster than the boost pointer containers. More importantly, the interface for an STL container of smart_ptr is a 100% compatible with STL containers, which is not the case with the boost pointer containers. smart_ptr has a policy that allows it to synchronize access to both the smart pointer and the pointee. The smart_ptr has been compiled and tested on VC++ 6.0, 7.1, 8.0, GNU 3.x, Borland 5.5, and Comeau 4.3.
