std::error_condition(3) C++ Standard Libary std::error_condition(3) NAME std::error_condition - std::error_condition Synopsis Defined in header <system_error> class error_condition; (since C++11) std::error_condition is a platform-independent error code. Like std::error_code, it is uniquely identified by an integer value and a std::error_cate- gory, but unlike std::error_code, the value is not platform-dependent. A typical implementation holds one integer data member (the value) and a pointer to an std::error_category. Member functions constructor constructs an error_condition (public member function) operator= replaces the contents (public member function) assign replaces the contents (public member function) clear sets the error_condition to value 0 in generic_cate- gory (public member function) value obtains the value of the error_condition (public member function) category obtains the error_category for this error_condition (public member function) message obtains the explanatory string (public member function) operator bool checks if the value is non-zero (public member function) Non-member functions operator== operator!= operator< compares error_conditions and error_codes operator<=> (function) (removed in C++20) (removed in C++20) (C++20) Helper classes is_error_condition_enum identifies an enumeration as an std::error_condition (C++11) (class template) std::hash<std::error_condition> hash support for std::error_condi- tion (C++17) (class template specialization) See also error_code holds a platform-dependent error code (C++11) (class) error_category base class for error categories (C++11) (class) make_error_condition(std::errc) constructs an std::errc error condi- tion (C++11) (function) http://cppreference.com 2022.07.31 std::error_condition(3)
