error_code make_error_code(io_errc e) noexcept;

#

Returns: error_­code(static_­cast<int>(e), iostream_­category()).

error_condition make_error_condition(io_errc e) noexcept;
2
#

Returns: error_­condition(static_­cast<int>(e), iostream_­category()).

const error_category& iostream_category() noexcept;
3
#

Returns: A reference to an object of a type derived from class error_­category.

The object's default_­error_­condition and equivalent virtual functions shall behave as specified for the class error_­category. The object's name virtual function shall return a pointer to the string "iostream".
