error_condition() noexcept; | (1) | (since C++11)
error_condition( int val, const error_category& cat ) noexcept; | (2) | (since C++11)
template< class ErrorConditionEnum > error_condition( ErrorConditionEnum e ) noexcept; | (3) | (since C++11)

error_condition( error_condition&& other ) = default; | (5) | (since C++11) (implicitly declared)

Constructs new error condition.

1) Default constructor. Initializes the error condition with generic category and error value ​0​.
2) Initializes the error condition with error value `val` and error category `cat`.
3) Initializes the error condition with enum `e`. Effectively calls `make_error_condition` that is only found by argument-dependent lookup for `e`. This overload participates in overload resolution only if std::is_error_condition_enum <ErrorConditionEnum>::value is true.
4,5) Implicitly defined copy constructor and move constructor. Initializes the error condition with the contents of the `other`.

### Parameters

other | - | another error condition to initialize with
val | - | error value
cat | - | error category
e | - | error condition enum

DR | Applied to | Behavior as published | Correct behavior
--- | --- | --- | ---
LWG 3629 | C++11 | only `std::make_error_condition` overloads were used | ADL-found overloads are used
