-The function opens file storage for reading or writing data. In the latter case, a new file is created or an existing file is rewritten. The type of the read or written file is determined by the filename extension:  ``.xml`` for  ``XML`` and  ``.yml`` or  ``.yaml`` for  ``YAML``. The function returns a pointer to the :ocv:struct:`CvFileStorage` structure.
