27.7.2 Input streams [input.streams] Class template basic_iostream [iostreamclass] basic_iostream constructors [iostream.cons]

explicit basic_iostream(basic_streambuf<charT,traits>* sb);

Effects: Constructs an object of class basic_iostream, assigning initial values to the base classes by calling basic_istream<charT,traits>(sb) ([istream]) and basic_ostream<charT,traits>(sb) ([ostream])

Postcondition: rdbuf()==sb and gcount()==0.

basic_iostream(basic_iostream&& rhs);

Effects: Move constructs from the rvalue rhs by constructing the basic_istream base class with move(rhs).
