I have a library here which I would propose for addition to Boost. It is a wrapper around a resource handle, just like std::auto_ptr is a wrapper around a pointer. The main difference to std::auto_ptr is that it doesn't overload operator-> and that it can (or, rather, must) be customized. Therefore it can also be used to hold resources like 'int' (a Unix filedescriptor) or 'FILE*' and also has the known ownership transfer semantics of std::auto_ptr.
I'm interested. Long ago, I wrote something very much like what you describe (see http://msdn.microsoft.com/msdnmag/issues/03/06/ResourceManagement/default.as...), and used it effectively to plug the resource leaks in an application I inherited. I think there is a need for more general RAII resource managers. -- Eric Niebler Boost Consulting www.boost-consulting.com
