Part . Memory and Resource Management

Smart pointers and std::auto_ptr are key tools at our disposal for safe and efficient management of memory and other resources, including real-world objects such as disk files and database transaction locks. How can we safely use auto_ptr and use common design patterns to adapt it in order to avoid common pitfalls? Can you use auto_ptr as a class member, and what must you absolutely be aware of if you do elect to use it that way? Finally, can you avoid the problem by doing better, by writing a special-purpose smart pointer designed to hold a member object at arm's length? Indeed you can. Indeed you can…
