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

[edit] Parameters

st - new value for the state

[edit] Return value

1) the current value of the fpos state
2) (none)

[edit] Example

#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
