std::fpos

Member functions

fpos::state

 

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

1) obtains the value of the file position state

2) changes the value of the file position state

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
