Start and end point of an arc in toolkit

[SN_10773997]

How can I get the start and end point (as a pfcPoint3D_ptr) using a pfcArcDescriptor_ptr object in object toolkit c++?

It seems no one is willing, so here to get a clue for Toolkit,

You may have an edge or a curve. For a curve

    err= ProCurveInit(model,geom_id,&p_curve_data);
    err = ProCurvedataTypeGet(p_curve_data, &c_type);
    switch(c_type)
....

    case PRO_ENT_ARC:
	err = ProArcdataGet(p_curve_data, v1, v2, p1, &st_a, &en_a, &rad);
...

/* or
dataPtr->data.p_curve_data->arc.vector1[0] and 1 and 2
dataPtr->data.p_curve_data->arc.vector2[0] and 1 and 2
dataPtr->data.p_curve_data->arc.origin[0] and 1 and 2
dataPtr->data.p_curve_data->arc.start_angle
dataPtr->data.p_curve_data->arc.end_angle;
dataPtr->data.p_curve_data->arc.radius;

*/

Check UtilIntfData.c 

For an edge it is similar ....
