- \brief Outputs emptiness.
- ... = any variadic parameters. The parameters are ignored.
-
- This macro is used to output emptiness ( nothing ) no matter
- what is passed to it.
-
- If you use this macro to return a result, as in 'result BOOST_VMD_EMPTY'
- subsequently invoked, you should surround the result with
- BOOST_VMD_IDENTITY_RESULT to smooth over a VC++ problem.
