shp_multipointm_pointm()

void shp_multipointm_pointm	(	const shp_multipointm_t *	multipointm,
		size_t	point_num,
		shp_pointm_t *	pointm
	)

Gets a PointM and a measure from a MultiPointM.

Example

// Iterate over all points
size_t i;
shp_pointm_t pointm;
 
for (i = 0; i < multipointm->num_points; ++i) {
  shp_multipointm_pointm(multipoint, i, &pointm);
}

Parameters

	multipointm	a shp_multipointm_t structure.
	point_num	a zero-based point number.
[out]	pointm	a shp_pointm_t structure.
