Stephan T. Lavavej is back in front of the Channel 9 cameras once again for a discussion on our recently implemented C++0x feature “nullptr”. In a previous channel 9 appearance, Stephan spoke about the C++0x language and library features we were implementing for VS2010 and the various interdependencies between various features (for example, how rvalue references – a language feature – enable move semantics and perfect forwarding in our Standard Template Library implementation – a library feature.) In this video Stephan describes how rvalue references exposed a few loopholes in the C++ type system around the NULL macro (or more specifically around the value of the NULL macro, the integer constant 0, and how this value is treated “differently” by the compiler to other integer constants.) The issue had already been identified by the C++ Language Committee and a solution had been added to the C++0x language specification (the aforementioned “nullptr”). And to add even more good news, customers can see and use this feature (and all our other C++0x Features) in the Visual Studio 2010 Beta 2 which was released this week. We hope you enjoy Stephan’s latest theatrical release.
