Otherwise, returns an absolute path to 'file_name' considering it relative to 'dir_', which itself must be absolute. 'dir_' may be None or the empty string, in which case the current working directory is used. Returns None if 'dir_' is None and getcwd() fails. This differs from os.path.abspath() in that it will never change the meaning of a file name.
