27.6.3 Class template istreambuf_­iterator [istreambuf.iterator]

27.6.3.3 istreambuf_­iterator operations [istreambuf.iterator.ops]

charT operator*() const
Returns: The character obtained via the streambuf member sbuf_­->sgetc().
istreambuf_iterator& operator++();
Effects: As if by sbuf_­->sbumpc().
Returns: *this.
proxy operator++(int);
Returns: proxy(sbuf_­->sbumpc(), sbuf_­).
bool equal(const istreambuf_iterator& b) const;
Returns: true if and only if both iterators are at end-of-stream, or neither is at end-of-stream, regardless of what streambuf object they use.
template<class charT, class traits> bool operator==(const istreambuf_iterator<charT,traits>& a, const istreambuf_iterator<charT,traits>& b);
Returns: a.equal(b).
template<class charT, class traits> bool operator!=(const istreambuf_iterator<charT,traits>& a, const istreambuf_iterator<charT,traits>& b);
Returns: !a.equal(b).
