std::experi...ot_directory(3)

🎀 std::experimental::filesystem::path::root_directory 🎀

okay so bestie, this page is from the C++ Standard Libary manual — the page id is std::experi...ot_directory(3) — and it’s all about the member function std::experimental::filesystem::path::root_directory. no cap, it’s a tiny one, but every detail is staying. 💅

💖 NAME 💖

std::experimental::filesystem::path::root_directory — literally the same name, twice, because that’s how this page rolls. 🫶

✨ Synopsis ✨

Here’s the signature, copied exactly because we do not mess with code:

path root_directory() const;  (filesystem TS)

It returns the root directory of the path. If the path does not include root name, returns path(). (That’s the original wording, bestie — keep it close.) 🌸

🌈 Parameters 🌈

• (none) — yep, zero parameters. the void is the vibe. 💀

🦋 Return value 🦋

The root directory of the path. that’s it. that’s the return value. ✨

🔥 Exceptions 🔥

May throw implementation-defined exceptions. so like, it may throw, and the details are implementation-defined — no invented drama from me. 😭

🍓 Example 🍓

The original says “Run this code,” so here’s the code, exactly:

// Run this code

#include <experimental/filesystem>
#include <iostream>
namespace fs = std::experimental::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"
