std::basic_ios<CharT,Traits>:: rdstate

Returns the current stream error state.

Parameters

(none)

Return value

current stream error state. It is a bitmask type and can be a combination of the following constants:

Example

#include <iostream>
#include <sstream>
 
int main()
{
    std::ostringstream stream;
 
    if (stream.rdstate() == std::ios_base::goodbit)
        std::cout << "stream state is goodbit\n";
 
    stream.setstate(std::ios_base::eofbit);
 
    // check state is exactly eofbit (no failbit and no badbit)
    if (stream.rdstate() == std::ios_base::eofbit)
        std::cout << "stream state is eofbit\n";
}

stream state is goodbit
stream state is eofbit
