/** \def BOOST_VMD_EMPTY(...)
|
|
|
|
\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.
