std::basic_ostream<CharT,Traits>::basic_ostream (3) - Linux Man Pages
explicit basic_ostream( std::basic_streambuf<CharT, Traits>* sb ); (1)
protected: (2) (since C++11)

protected: (3) (since C++11)
basic_ostream( basic_ostream&& rhs );
1) Constructs the basic_ostream object, assigning initial values to the base class by calling basic_ios::init(sb).
2) The copy constructor is protected, and is deleted. Output streams are not copyable.
3) The move constructor uses basic_ios<CharT, Traits>::move(rhs) to move all basic_ios members, except for the rdbuf(), from rhs into *this. This move constructor is protected: it is called by the move constructors of movable output stream classes std::basic_ofstream and std::basic_ostringstream, which know how to correctly move the associated streambuffer.
sb - streambuffer to use as output sequence
rhs - basic_ostream to initialize from
