fs::path original_path("/home/user/documents/myfile.txt"); fs::string_type root_name = original_path.root_name().native(); fs::string_type root_dir = original_path.root_directory().native();This code creates a Boost filesystem path object for the file "/home/user/documents/myfile.txt" and then uses the "root_name()" and "root_directory()" methods to get the root name and root directory of the path. The "native()" method is used to convert the results to a native format. The "path native" feature is part of the Boost.Filesystem library, which is a separate package from the main Boost distribution. To use it, you need to include the appropriate headers and link against the filesystem library. Depending on your compiler and platform, you may need to specify additional options to your build system to make use of the library.
