std::error_condition::error_condition(3) | C++ Standard Libary | std::error_condition::error_condition(3) |
NAME¶
std::error_condition::error_condition - std::error_condition::error_condition
Synopsis¶
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 ) (3)
(since C++11)
noexcept;
template< class ErrorConditionEnum > (4) (since C++11)
error_condition( ErrorConditionEnum e ) noexcept;
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.
