std::error_condition::error_condition
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.
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.
