std::filesy...::root_path(3)

🌸 NAME 🌸

The manual page std::filesy...::root_path(3) is from the C++ Standard Libary (their spelling, not mine 💀), and it’s all about std::filesystem::path::root_path. The original name line is literally std::filesystem::path::root_path - std::filesystem::path::root_path, which is iconic in a deeply unhinged way. 💅

✨ Synopsis ✨

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

Returns the root path of the path. If the path does not include root path, returns path().

Effectively returns root_name() / root_directory().

🫶 Parameters 🫶

(none) — zero, nada, no arguments. It’s giving low-maintenance icon. ✨

🎀 Return value 🎀

The root path of the path. That’s the whole vibe. 🎀

😭 Exceptions 😭

May throw implementation-defined exceptions. So like… your implementation gets to decide the drama level, bestie. 😭

💻 Example 💻

The page says // Run this code right before the snippet, so here’s the exact code:

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

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

Possible output:

Current root path is: "C:\"
