std::error_code::error_code

1	`error_code();`

(1)

(since C++11)

1	`error_code(` `int` `ec,` `const` `error_category& ecat );`

(2)

(since C++11)

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

Exceptions

noexcept specification:
