    Perform a stat system call on the given path.
    
      path
        Path to be examined; can be string, bytes, path-like object or
        open-file-descriptor int.
      dir_fd
        If not None, it should be a file descriptor open to a directory,
        and path should be a relative string; path will then be relative to
        that directory.
      follow_symlinks
        If False, and the last element of the path is a symbolic link,
        stat will examine the symbolic link itself instead of the file
        the link points to.
    
    dir_fd and follow_symlinks may not be implemented
      on your platform.  If they are unavailable, using them will raise a
      NotImplementedError.
    
    It's an error to use dir_fd or follow_symlinks when specifying path as
      an open file descriptor.
