Re: [boost] [config] Macro for null pointer

I have found something like this to be helpful, when working with multiple compilers:

#include <boost/config.hpp> #if defined(BOOST_NO_NULLPTR) #define BOOST_XXX_NULLPTR 0 #else #define BOOST_XXX_NULLPTR nullptr #endif

where XXX is some local name for my own use. And then use BOOST_XXX_NULLPTR in places where a null pointer is needed.

Would this be a candidate for a BOOST_NULLPTR macro in the config library instead ?

Might it be better to just offer a (albeit imperfect) nullptr emulation if not supplied by the compiler? For example, [1]. - Jeff [1] http://en.wikibooks.org/wiki/More_C%2B%2B_Idioms/nullptr
