std::experimental::filesystem::recursive_directory_iterator::depth

Returns the number of directories from the starting directory to the currently iterated directory, i.e. the current depth of the directory hierarchy.

# Declarations

int depth() const;

(filesystem TS)

# Return value

Current depth of the directory hierarchy.

# Example

#include <experimental/filesystem>
#include <fstream>
#include <iostream>
#include <string>
namespace fs = std::experimental::filesystem;
 
int main()
{
    fs::create_directories("sandbox/a/b/c");
    fs::create_directories("sandbox/a/b/d/e");
    std::ofstream("sandbox/a/b/file1.txt");
    fs::create_symlink("a", "sandbox/syma");
    for (auto i = fs::recursive_directory_iterator("sandbox");                       
             i != fs::recursive_directory_iterator(); ++i)
    {
        std::cout << std::string(i.depth(), ' ') << *i;
        if (fs::is_symlink(i->symlink_status()))
            std::cout << " -> " << fs::read_symlink(*i);
        std::cout << '\n';
    }
    fs::remove_all("sandbox");
