9 Iterators library [iterators]

9.8 Stream iterators [iterators.stream]

9.8.3 Class template istreambuf_iterator [istreambuf.iterator]

9.8.3.7 operator!= [istreambuf.iterator::op!=]

template <class charT, class traits> bool operator!=(const istreambuf_iterator<charT, traits>& a, const istreambuf_iterator<charT, traits>& b); template <class charT, class traits> bool operator!=(default_sentinel a, const istreambuf_iterator<charT, traits>& b); template <class charT, class traits> bool operator!=(const istreambuf_iterator<charT, traits>& a, default_sentinel b);

Effects: Equivalent to: return !(a == b);
