30.7.5 Output streams [output.streams] Class template basic_­ostream [ostream] basic_­ostream constructors [ostream.cons]

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

Effects: Constructs an object of class basic_­ostream, initializing the base class subobject with basic_­ios<charT, traits>​::​init(sb) ([basic.ios.cons]).

Postconditions: rdbuf() == sb.

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.

virtual ~basic_ostream();

Effects: Destroys an object of class basic_­ostream.

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