 (1) (seit C++11)
error_code( int ec, const error_category& ecat );
 (2) (seit C++11)
template< class ErrorCodeEnum > error_code( ErrorCodeEnum e );
 (3) (seit 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.

Parameter

ec - platform dependent error code to construct with
ecat -
