posesegm_locate() long double posesegm_locate ( const Pose *  start, const Pose *  end, const Pose *  value  ) Return a float in (0,1) if a network point segment intersects a network point, return -1.0 if the network point is not located in the segment or if it is approximately equal to the start or the end valuess. Parameters [in] start,end Values defining the segment [in] value Value to locate Note The function returns -1.0 if the network point is approximately equal to the start or the end network points since it is used in the lifting infrastructure for determining the crossings or the turning points after verifying that the bounds of the segment are not equal to the value.
