std::experimental::filesystem::begin(directory_iterator),(3)

NAME
std::experimental::filesystem::begin(directory_iterator), - std::experimental::filesystem::begin(directory_iterator),

Synopsis
   directory_iterator begin( directory_iterator iter ); (1) (filesystem TS)
   directory_iterator end( const directory_iterator& ); (2) (filesystem TS)
   1) Returns iter unchanged.
   2) Returns a default-constructed directory_iterator, which serves as the end
   iterator. The argument is ignored.
   These non-member functions enable the use of directory_iterators with range-based
   for loops.

Parameters
   iter - a directory_iterator

Return value
   1) iter unchanged.
   2) End iterator (default-constructed directory_iterator).

Exceptions
   noexcept specification:
   noexcept

Example
// Run this code
 #include <experimental/filesystem>
 #include <fstream>
 #include <iostream>
 namespace fs = std::experimental::filesystem;
 int main()
 {
     fs::create_directories("sandbox/a/b");
     std::ofstream("sandbox/file1.txt");
     std::ofstream("sandbox/file2.txt");
     for (auto& p : fs::directory_iterator("sandbox"))
         std::cout << p << '\n';
     fs::remove_all("sandbox");
 }

Possible output:
 "sandbox/a"
 "sandbox/file1.txt"
 "sandbox/file2.txt"
