我在UISTYLER对话框的一个按钮中调用下边的这个子函数，但是运行了下边的这个函数的相应功能后，随后在这个子函数下边的任何语句就不在执行了，真的好奇怪，下面是我的在按钮中要调用的子函数，我怀疑是这个子函数的问题，请各位高手指点！

static void get_intersect(tag_t curve, tag_t face, double tol)
{
  int  type;
  UF_CALL(UF_MODL_intersect_objects(curve,face,tol,[$num_intersects,&intersect_data))]

  printf("\n Number of intersections = %d\n", num_intersects);

  for(i = 0; i < num_intersects; i++)
  {
    type = (intersect_data)->intersect_type;
    switch(type)
    {
      case UF_MODL_INTERSECT_POINT:

        printf("\nx,y,z coordinates are: (%f, %f, %f)\n",
               (intersect_data)->intersect.point.coords[0],
               (intersect_data)->intersect.point.coords[1],
               (intersect_data)->intersect.point.coords[2]);

        printf("Object 1 UV parameters are: (%f, %f)\n",
               (intersect_data)->intersect.point.object_1_u_parm,
               (intersect_data)->intersect.point.object_1_v_parm);

        printf("Object 2 UV parameters are: (%f, %f)\n",
               (intersect_data)->intersect.point.object_2_u_parm,
               (intersect_data)->intersect.point.object_2_v_parm);

        break;

       case UF_MODL_INTERSECT_COINCIDE:

        printf("\nCoincident curve tag is: %d\n",
               intersect_data->intersect.coincide.identifier);

        printf("Object 1 UV parameters are: (%f, %f)\n",
               intersect_data->intersect.coincide.object_1_first_parm,
               intersect_data->intersect.coincide.object_1_second_parm);

        printf("Object 2 UV parameters are: (%f, %f)\n",
               intersect_data->intersect.coincide.object_2_first_parm,
               intersect_data->intersect.coincide.object_2_second_parm);
        break;
        case UF_MODL_INTERSECT_CURVE:
    UF_CALL(UF_MODL_create_list([$loop_list))]
       for(i=0;i<num_intersects;i++)
   {
       UF_CALL(UF_MODL_put_list_item(loop_list, intersect_data->intersect.curve.identifier));
   }

       UF_CALL(UF_MODL_create_extruded(loop_list, taper_angle, limit1,
                          ref_pt, direction, create, [$features))]
       
   UF_CALL(UF_MODL_create_extruded(loop_list, taper_angle, limit1,
                          ref_pt, direction2, create, [$features2))]

        break;

        default:

        printf("\nSomething went wrong, we shouldn't be here!");
        break;
    
    }

    /* Free each element of the array. */
      UF_free(intersect_data);
  }

  if(num_intersects != 0)
  {
    /* Free the array. */
    UF_free(intersect_data);
  }
}
