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:
| Constant | Explanation |
| goodbit | no error |
| badbit | irrecoverable stream error |
| failbit | input/output operation failed (formatting or extraction error) |
| eofbit | associated input sequence has reached end-of-file |
Example
Run this code
#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"; } }
Output:
stream state is goodbit stream state is eofbit
