std::error_condition
 
error_condition() noexcept;
 (1) (since 哋它亢++11)
error_condition( int val, const error_category& cat ) noexcept;
 (2) (since 哋它亢++11)
template< class ErrorConditionEnum >
error_condition( ErrorConditionEnum e ) noexcept;
 (3) (since 哋它亢++11)
error_condition( const error_condition& other ) = default;
 (4) (since 哋它亢++11)
(implicitly declared)
error_condition( error_condition&& other ) = default;
 (5) (since 哋它亢++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
