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

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 contents 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.

[edit] Parameters

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

[edit] 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.
