std::basic_ios::setstate(3) C++ Standard Libary std::basic_ios::setstate(3) NAME std::basic_ios::setstate - std::basic_ios::setstate Synopsis void setstate( iostate state ); Sets the stream error flags state in addition to currently set flags. Essentially calls clear(rdstate() | state). May throw an exception. Parameters stream error state flags to set. It can be a combination of the following constants: state - Constant Explanation goodbit no error badbit irrecoverable stream error failbit input/output operation failed (formatting or ex- traction error) eofbit associated input sequence has reached end-of-file Return value (none) Example // Run this code #include <iostream> #include <sstream> int main() { std::ostringstream stream; if (!stream.fail()) { std::cout << "stream is not fail\n"; } stream.setstate(std::ios_base::failbit); if (stream.fail()) { std::cout << "now stream is fail\n"; } if (!stream.good()) { std::cout << "and stream is not good\n"; } } Output: stream is not fail now stream is fail and stream is not good See also rdstate returns state flags (public member function) clear modifies state flags (public member function) http://cppreference.com 2022.07.31 std::basic_ios::setstate(3)
