std::istreambuf_iterator<CharT,Traits>::operator++, operator++(int)

istreambuf_iterator& operator++();
 (1) 
/* proxy */ 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) A proxy object holding the current character obtained via operator*() and the sbuf_ pointer. Dereferencing a proxy object with operator* yields the stored character.
The name proxy is for exposition only.

Exceptions

(none).
