std::error_...or_condition(3) C++ Standard Libarystd::error_...or_condition(3) NAME std::error_condition::error_condition - std::error_condition::er- ror_condition Synopsis error_condition() noexcept; (1) (since C++11) error_condition( const error_condition& other ) noexcept; (2) (since C++11) (im- plicitly declared) error_condition( int val, const error_category& cat ) (3) (since C++11) noexcept; template< class ErrorConditionEnum > (4) (since C++11) error_condition( ErrorConditionEnum e ) noexcept; Constructs new error condition. 1) Default constructor. Initializes the error condition with generic category and error code 0. 2) Copy constructor. Initializes the error condition with the con- tents of other. 3) Initializes the error condition with error code val and error category cat. 4) Initializes the error condition with enum e. Effectively calls make_error_condition found by argument-dependent lookup for e. This overload participates in overload resolution only if std::is_error_condition_enum<ErrorConditionEnum>::value is true. Parameters other - another error condition to initialize with val - error code cat - error category e - error condition enum Notes The ADL-found make_error_condition is intended to be used in the original proposal N2422, and used by all known implementations. However, the standard requires that only std::make_error_condition overloads are considered. This is LWG issue 3629.
