Sets additional flags.
void setstate(
iostate _State
);
Parameters
- _State
Additional flags to set.
Remarks
The member function effectively calls clear(_State | rdstate).
Example
// basic_ios_setstate.cpp
// compile with: /EHsc
#include <ios>
#include <iostream>
using namespace std;
int main( )
{
bool b = cout.bad( );
cout << b << endl; // Good
cout.clear( ios::badbit );
b = cout.bad( );
// cout.clear( );
cout << b << endl; // Is bad, good
b = cout.fail( );
cout << b << endl; // Not failed
cout.setstate( ios::failbit );
b = cout.fail( );
cout.clear( );
cout << b << endl; // Is failed, good
return 0;
}
