29.11.12 Class directory_iterator [fs.class.directory.iterator]

29.11.12.1 Members [fs.dir.itr.members]

directory_iterator() noexcept;

Effects: Constructs the end iterator.

🔗

explicit directory_iterator(const path& p);
directory_iterator(const path& p, directory_options options);
directory_iterator(const path& p, error_code& ec);
directory_iterator(const path& p, directory_options options, error_code& ec);

Effects: For the directory that p resolves to, constructs an iterator for the first element in a sequence of directory_entry elements representing the files in the directory, if any; otherwise the end iterator.

However, if

(options & directory_options::skip_permission_denied) != directory_options::none

and construction encounters an error indicating that permission to access p is denied, constructs the end iterator and does not report an error.

Throws: As specified in [fs.err.report].

[Note

To iterate over the current directory, use directory_iterator(".") rather than directory_iterator("").

directory_iterator(const directory_iterator& rhs);
directory_iterator(directory_iterator&& rhs) noexcept;

Postconditions: *this has the original value of rhs.

directory_iterator& operator=(const directory_iterator& rhs);
directory_iterator& operator=(directory_iterator&& rhs) noexcept;

Effects: If *this and rhs are the same object, the member has no effect.
