Non-member functions

operator<<

 

const std::filesystem::path& path() const noexcept;		(since C++17)
operator const std::filesystem::path& () const noexcept;		(since C++17)

Returns the full path the directory entry refers to.

Parameters

(none)

Return value

The full path the directory entry refers to.

Example

Run this code

#include <filesystem>
#include <fstream>
#include <iostream>
 
namespace fs = std::filesystem;
 
std::string get_stem(const fs::path &p) { return (p.stem().string()); }
void create_file(const fs::path &p) { std::ofstream o{p}; }
 
int main()
{
        const fs::path dir{"tmp_dir"};
        fs::create_directory(dir);
        create_file(dir / "one");
        create_file(dir / "two");
        create_file(dir / "three");
 
        for (const auto &file : fs::directory_iterator(dir)) {
                // Explicit conversion
                std::cout << get_stem(file.path()) << '\n';
 
                // Implicit conversion
                std::cout << get_stem(file) << '\n';
        }
 
        fs::remove_all(dir);
}

Possible output:

two
two
one
one
three
three
