pointsegm_locate_point() long double pointsegm_locate_point ( Datum  start, Datum  end, Datum  point, double *  dist  ) Return a float between 0 and 1 representing the location of the closest point on the geometry segment to the given point, as a fraction of total segment length. Parameters [in] start,end Points defining the segment [in] point Reference point [out] dist Distance Note This is the previous version of the function that is kept here while recovering the CI tests. This function should be merged with the function pointsegm_locate below
