CharT operator*() const;	(1)
pointer operator->() const;	(2)	(since C++11) (until C++17)

Reads a single character by calling sbuf_->sgetc() 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) The value of the obtained character.

2) An object of unspecified type, such that given an istreambuf iterator i, the expressions (*i).m and i->m have the same effect.

Exceptions

(none)
