std::error_...::error_code(3)  C++ Standard Libary std::error_...::error_code(3)

NAME
     std::error_code::error_code - std::error_code::error_code

Synopsis
	error_code()  noexcept; 				     (1)  (since
     C++11)
	error_code( int ec, const error_category& ecat )  noexcept;  (2)  (since
     C++11)
	template<  class  ErrorCodeEnum  >			      (3) (since
     C++11)
	error_code( ErrorCodeEnum e ) noexcept;
	error_code( const error_code& other ) =  default;	     (4)  (since
     C++11)
								       (implic-
     itly declared)
	error_code(  error_code&&  other  ) = default;		      (5) (since
     C++11)
								       (implic-
     itly declared)

	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
	make_error_code(e),  where make_error_code is only found by argument-de-
     pendent
	lookup. This overload participates in overload resolution only if
	std::is_error_code_enum<ErrorCodeEnum>::value is true.
	4,5) Implicitly defined copy constructor and move constructor.	Initial-
     izes the error
	code with the contents of the other.

Parameters
	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
