std::experimental::filesystem::recursive_directory_iterator

From cppreference.com
< cpp‎ | experimental‎ | fs
Defined in header <experimental/filesystem>
class recursive_directory_iterator :
    public std::iterator<input_iterator_tag, directory_entry>;
(filesystem TS)

recursive_directory_iterator is an input iterator that can recursively advance through entries of a directory and its children directories. Directory iteration never returns directory entries to the current (dot) and parent (dot-dot) directories. The order of directory entries is unspecified.

The past-the-end iterator (simply called the end iterator) is a special iterator. An end iterator is always equal to an end iterator and never equal to a non-end iterator. An end iterator is created by the default constructor of directory iterator and when a directory iterator is advanced past the last directory element. Calling operator* or operator-> on an end iterator yields undefined behavior.

If a file in a directory is deleted after the directory iterator has been created, the directory iterator may return a directory entry to the deleted file. If, on the other hand, a new file is created after the directory iterator has been created, iteration of the directory is not guaranteed to return a directory entry to the new file.
