std::fpos<State>::state (3) - Linux Man Pages

std::fpos<State>::state: std::fpos<State>::state

NAME

std::fpos<State>::state - std::fpos<State>::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 <iostream>
  #include <sstream>
  #include <cwchar>


  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
