Type Lib would help if you would like to distinguish only one type or some
Good Luck,Ovanes

special type characteristic. There are some nice traits like: is_same, or is_base_of, or is_fundamental, or is_scalar, or is_integral etc. probably wouldn't have worked.I had a feeling the MPL library would be involved, but I wanted to make sure the type_traits library didn't already have something in place for this kind of situation. Thanks again!

If you only have 2 'valid' types then it's easier to use mpl::or_ instead of mpl::set. #include <boost/utility/enable_if.hpp> #include <boost/type_traits/is_same.hpp> #include <boost/mpl/or.hpp> using namespace boost; using namespace boost::mpl; template<class T> void foo ( T, typename enable_if < or_<is_same<T, char>, is_same<T, wchar_t> >
