al_load_ttf_font_f - Allegro 5 API

       Like  al_load_ttf_font(3alleg5), but the font is read from the file handle.  The filename is only used to
       find possible additional files next to a font file.

              Note: The file handle is owned by the returned ALLEGRO_FONT object and must not be  freed  by  the
              caller, as FreeType expects to be able to read from it at a later time.
