Moves an iterator by a specified distance.
template< typename I, int N > struct advance_c { typedef unspecified type; };
Table 1.18. Parameters
| Parameter | Requirement | Description | 
|---|---|---|
| 
                     | Model of Forward Iterator | Iterator to move relative to | 
| 
                     | Integer constant | Number of positions to move | 
result_of::advance_c<I, N>::type
          Return type: A model of the same iterator
          concept as I.
        
          Semantics: Returns an iterator a distance
          N from I.
          If I is a Bidirectional
          Iterator then N
          may be negative. Equivalent to result_of::advance<I, boost::mpl::int_<N> >::type
#include <boost/fusion/iterator/advance.hpp> #include <boost/fusion/include/advance.hpp>
typedefvector<int,double,char> vec; typedefresult_of::begin<vec>::type first; typedefresult_of::next<first>::type second; typedefresult_of::next<second>::type third; BOOST_MPL_ASSERT((result_of::equal_to<result_of::advance_c<first, 2>::type, third>));
