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 |
