std::filesy...::root_name(3)

🌸 NAME 🌸

okay so this page is literally std::filesystem::path::root_name - std::filesystem::path::root_name (yes, she said it twice, and she ate 💅). We’re chilling in the C++ Standard Libary manual under the std::filesy...::root_name(3) banner, and this whole page is about the std::filesystem::path::root_name member function. no cap. 🎀

---

✨ Synopsis ✨

path root_name() const;  (since C++17)

This one returns the root name of the generic-format path. If the path (in generic format) does not include root name, it returns path(). that’s the vibe check, bestie. 🦋

---

🫶 Parameters 🫶

• (none) — literally no parameters. zero. nada. she takes nothing and still serves. ✨

---

💖 Return value 💖

The root name of the path. periodt. 🍓

---

😭 Exceptions 😭

May throw implementation-defined exceptions. so like, the implementation gets to pick the drama, and you just gotta deal. 💀

---

🔥 Example 🔥

Run this code, bestie:

// Run this code

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

int main()
{
    std::cout << "Current root name is: " <<
       fs::current_path().root_name() << '\n';
}

Possible output:

Current root name is: "C:"
