Constructs new error code.
error_code(0, std::system_category())
.ec
as the platform-dependent error code and ecat
as the corresponding error category.e
. Equivalent to make_error_code(e)
, where make_error_code
is only found by argument-dependent lookup. This overload participates in overload resolution only if std::is_error_code_enum<ErrorCodeEnum>::value
is true
.other
.other | - | another error code to initialize with |
ec | - | platform dependent error code to construct with |
ecat | - | error category corresponding to ec |
e | - | error code enum to construct with |

LWG 3629 | C++11 | only std::make_error_code overloads were used | ADL-found overloads are used |
(C++11) | constructs an std::errc error code (function) |
(C++11) | constructs an iostream error code (function) |
(C++11) | constructs a future error code (function) |
