std::error_...operatorbool(3) C++ Standard Libary std::error_...operatorbool(3) NAME std::error_code::operatorbool - std::error_code::operatorbool Synopsis explicit operator bool() const noexcept; (since C++11) Checks if the error code value is valid, i.e. non-zero. Parameters (none) Return value false if value() == 0, true otherwise. Notes Although this operator is often used as a convenient shorthand to check if any error was returned, as in if (ec) { /* handle error */ }, such use is not ro- bust: some error codes, for example, HTTP status code 200, may indicate success as well. http://cppreference.com 2024.06.10 std::error_...operatorbool(3)
