27.7.3 Output streams [output.streams] basic_ostream constructors [ostream.cons]

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

Effects: Constructs an object of class basic_ostream, assigning initial values to the base class by calling basic_ios<charT,traits>::init(sb) ([basic.ios.cons]).

Postcondition: rdbuf() == sb.

virtual ~basic_ostream();

Effects: Destroys an object of class basic_ostream.

Remarks: Does not perform any operations on rdbuf().

basic_ostream(basic_ostream&& rhs);

Effects: Move constructs from the rvalue rhs. This is accomplished by default constructing the base class and calling basic_ios<charT, traits>::move(rhs) to initialize the base class.
