// In header: <boost/algorithm/string/predicate.hpp>


template<typename Range1T, typename Range2T, typename PredicateT> 
  bool lexicographical_compare(const Range1T & Arg1, const Range2T & Arg2, 
                               PredicateT Pred);
template<typename Range1T, typename Range2T> 
  bool lexicographical_compare(const Range1T & Arg1, const Range2T & Arg2);

Description

This predicate is an overload of std::lexicographical_compare for range arguments

It check whether the first argument is lexicographically less then the second one.

If the optional predicate is specified, it is used for character-wise comparison
