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 .
[edit] Parameters
st
-
new value for the state
[edit] Return value
1) The current value of the
fpos state.2) (none)
[edit] 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
