Synopsis

// In header: <boost/algorithm/cxx11/copy_if.hpp>


template<typename InputIterator, typename OutputIterator, 
         typename CopyPredicate, typename TerminatePred> 
  BOOST_CXX14_CONSTEXPR std::pair< InputIterator, OutputIterator > 
  copy_if_while(InputIterator first, InputIterator last, 
                OutputIterator result, CopyPredicate copy_pred, 
                TerminatePred term_pred);

Description

Parameters:

`first`	The start of the input sequence
`last`	One past the end of the input sequence
`result`	An output iterator to write the results into
`copy_pred`	A predicate for testing whether to the current element
`term_pred`	A predicate for testing whether to end the copy operation

Returns:
