std::fpos::state(3)	      C++ Standard Libary	   std::fpos::state(3)

NAME
       std::fpos::state	- std::fpos::state

Synopsis
	  State	state()	const;	  (1)
	  void state( State st ); (2)

	  Manages the file position state.

	  1) Returns the value of the file position state.
	  2) Replaces the file position	state with the value of	st.

	  For  the  specializations of std::fpos that are used in the standard
       library,	State is
	  always std::mbstate_t.

Parameters
	  st - new value for the state

Return value
	  1) The current value of the fpos state.
	  2) (none)

Example
       // Run this code

	#include <cwchar>
	#include <iostream>
	#include <sstream>

	int main()
	{
	    std::istringstream s("test");
	    std::mbstate_t st =	s.tellg().state();

	    if (std::mbsinit(&st))
		std::cout << "The stream is in the initial shift state\n";
	}

Output:
	The stream is in the initial shift state
