std::experimental::filesystem::begin(directory_iterator),std::experimental::filesystem::end(directory_iterator) – std::experimental::filesystem::begin(directory_iterator),std::experimental::filesystem::end(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 <fstream>

#include <iostream>

#include <experimental/filesystem>

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"
