# std::filesystem::path::root_directory

From cppreference.com
< cpp‎ | filesystem‎ | path

path root_directory() const; |  | (since C++17)

Returns the root directory of the generic-format path. If the path (in generic format) does not include root directory, returns path().

### Parameters

(none)

### Return value

The root directory of the path.

### Exceptions

May throw implementation-defined exceptions.

### Example

Run this code

    #include <iostream>
    #include <filesystem>
    namespace fs = std::filesystem;

    int main()
    {
        fs::path p = fs::current_path();

        std::cout << "The current path " << p << " decomposes into:\n"
                  << "root name " << p.root_name() << '\n'
                  << "root directory " << p.root_directory() << '\n'
                  << "relative path " << p.relative_path() << '\n';
    }

Possible output:

    The current path "C:\Users\abcdef\Local Settings\temp" decomposes into:
    root name "C:"
    root directory "\"
    relative path "Users\abcdef\Local Settings\temp"
