std::filesy...ot_directory(3) C++ Standard Libarystd::filesy...ot_directory(3)

NAME
       std::filesystem::path::root_directory - std::filesystem::path::root_di-
       rectory

Synopsis
	  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"

See also
	  root_name returns the	root-name of the path, if present
		    (public member function)
	  root_path returns the	root path of the path, if present
		    (public member function)
