recursive_directory_iterator begin( recursive_directory_iterator iter );
(1) (filesystem TS)
recursive_directory_iterator end( const recursive_directory_iterator& );
(2) (filesystem TS)
1) Returns iter unchanged
2) Returns a default-constructed recursive_directory_iterator, which serves as the end iterator. The argument is ignored.

These non-member functions enable the use of recursive_directory_iterators with range-based for loops.

Parameters

iter - a recursive_directory_iterator

Return value

1) iter unchanged
2) End iterator (default-constructed recursive_directory_iterator)

Exceptions

noexcept specification:  
noexcept
  

Example

#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");
    fs::create_symlink("a", "sandbox/syma");
    for(auto& p: fs::recursive_directory_iterator("sandbox"))
        std::cout << p << '\n';
    fs::remove_all("sandbox");
}

Possible output:

"sandbox/a"
"sandbox/a/b"
"sandbox/file1.txt"
"sandbox/syma"
