template< class ErrorCodeEnum > error_code( ErrorCodeEnum e ); | (3) | (since C++11) |
Constructs new error code.
1) Constructs error code with default value. Equivalent to
error_code(0, std::system_category())
. 2) Constructs error code with
ec
as the platform-dependent error code and ecat
as the corresponding error category. 3) Constructs error code from an error code enum
e
. Equivalent to *this = std::make_error_code(e)
. The overload participates in overload resolutions only if std::is_error_code_enum<ErrorCodeEnum>::value == true
.Parameters
ec | - | platform dependent error code to construct with |
ecat | - | error category corresponding to ec |
e | - | error code enum to construct with |
