Function Documentation

   template<typename _Iterator > _Siter_base<_Iterator>::iterator_type __gnu_debug::__base
       (_Iterator__it) [inline] Helper function to extract base iterator of random access safe
       iterator in order to reduce performance impact of debug mode. Limited to random access
       iterator because it is the only category for which it is possible to check for correct
       iterators order in the __valid_range function thanks to the < operator.

   template<typename _InputIterator > bool __gnu_debug::__valid_range_aux2 (const _InputIterator
       &, const _InputIterator &, std::input_iterator_tag) [inline] Can't test for a valid range
       with input iterators, because iteration may be destructive. So we just assume that the
       range is valid.
