tcbuffer_cbuffer_distance_turnpt() int tcbuffer_cbuffer_distance_turnpt ( Datum  start, Datum  end, Datum  value, TimestampTz  lower, TimestampTz  upper, TimestampTz *  t1, TimestampTz *  t2  ) Return 1 or 3 if a temporal circular buffer segment and a geometry point are at the minimum distance during the period defined by the output timestamps, return 0 otherwise. These are the turning points when computing the temporal distance. Parameters [in] start,end Values defining the segment [in] value Value to locate [in] lower,upper Timestampts defining the segment [out] t1,t2 Timestamps defining the resulting period, may be equal Precondition The segment is not constant.
