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)
