(filesystem TS)

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

Effectively, returns the following: root_name() / root_directory()


[edit] Parameters


[edit] Return value

The root path of the path.

[edit] Exceptions

May throw implementation-defined exceptions.

[edit] Example

#include <experimental/filesystem>
#include <iostream>
namespace fs = std::experimental::filesystem;
int main()
    std::cout << "Current root path is: " << fs::current_path().root_path() << '\n';

Possible output:

Current root path is: "C:\"
