[Boost-users] type trait for detecting unsigned integer

Is there a way to detect a unsigned integer? I would like to have a
template to replace a macro that checks a value is in a range. Here is
what I have so far:

      template <typename Limit_Type>
        static inline void in_range ( boost::uint32_t value, Limit_Type limit )
        {
          if ( value > limit )
            {
              throw errors::Internal_Exception ( errors::Internal_Exception::INVALID_VALUE );
            }
          }

I would like to replace the "boost::uint32_t" with a default typename
and check to see if the 'value' is an unsigned type.
