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
