Effects: Calls close() then move assigns from rhs.
After the move assignment *this has the observable state it would have had if it had been move constructed from rhs (see [filebuf.cons]).
2
#
Returns: *this.
void swap(basic_filebuf& rhs);
3
#
Effects: Exchanges the state of *this and rhs.
template <class charT, class traits> void swap(basic_filebuf<charT, traits>& x, basic_filebuf<charT, traits>& y);

Effects: As if by x.swap(y).
