NAME
       std::basic_ios::swap - std::basic_ios::swap

Synopsis
	  protected:				   (since C++11)
	  void swap( basic_ios&	other )	noexcept;

	  Exchanges  the  states of *this and other, except for	the associated
       rdbuf objects.
	  rdbuf() and other.rdbuf() returns the	 same  values  as  before  the
       call.

       functions of the
	  derived stream  classes  such	 as  std::basic_ofstream  or  std::ba-
       sic_istringstream,
	  which	know how to correctly swap the associated streambuffers.

Parameters
	  other	- the basic_ios	object to exchange the state with

Return value
	  (none)
