The macro checks to see if a sequence is a Boost PP tuple. A Boost PP tuple is preprocessor tokens enclosed by a set of parentheses with no preprocessing tokens before or after the parentheses. sequence = a possible tuple returns = 1 if the sequence is a Boost PP tuple, 0 if it is not. */ #define BOOST_VMD_IS_TUPLE(sequence) \ BOOST_VMD_DETAIL_IS_TUPLE(sequence) \ /**/ #endif /* BOOST_PP_VARIADICS */ #endif /* BOOST_VMD_IS_TUPLE_HPP */
