An object of type file_status stores information about the type and permissions of a file.

27.10.11.1 file_status constructors [file_status.cons]

explicit file_status() noexcept;

1

Postconditions: type() == file_type::none and permissions() == perms::unknown.

explicit file_status(file_type ft, perms prms = perms::unknown) noexcept;

2

Postconditions: type() == ft and permissions() == prms.

27.10.11.2 file_status observers [file_status.obs]

file_type type() const noexcept;

1

Returns: The value of type() specified by the postconditions of the most recent call to a constructor, operator=, or type(file_type) function.

perms permissions() const noexcept;

2

Returns: The value of permissions() specified by the postconditions of the most recent call to a constructor, operator=, or permissions(perms) function.
