Non-member functions

istreambuf_iterator& operator++();	(1)
/* unspecified */ operator++(int);	(2)

Advances the iterator by calling sbuf_->sbumpc() where sbuf_ is the stored pointer to the stream buffer.

The behavior is undefined if the iterator is end-of-stream iterator.

Parameters

(none)

Return value

1) *this.

2) An unspecified struct proxy holding the current character obtained via operator*() for later retrieval. proxy is implicitly convertible to CharT.

proxy also holds the value of sbuf_. istreambuf_iterator can be constructed from proxy.

Exceptions

(none)
