怎样用
extern UFUNEXPORT int UF_CURVE_section_from_planes

(

UF_CURVE_section_general_data_p_t general_data,  /* <I> Data provided
                                                      by the user to to be
                                                      used in creating the
                                                      section curve feature.
                                                      */

UF_CURVE_section_planes_data_p_t planes_data, /*<I>  Sectioning planes
                                                      and datum planes.*/

tag_t *section_curves    /* <O>
               Feature tag, if general_data->associate is 1, or
               Group tag of section curves if general_data->associate is 0
                                    and general_data->grouping is 0, or
               Group tag of groups of curves if general_data->associate is 0
                                    and general_data->grouping is 1  */
);
就是对第一二个参数不会设置，怎样调用UF_CURVE_section_general_data_p_t，尤其对
UF_CURVE_section_general_data_s中的tag_t *objects 怎样设置
