tcbuffersegm_dwithin_turnpt() int tcbuffersegm_dwithin_turnpt ( Datum  start1, Datum  end1, Datum  start2, Datum  end2, Datum  dist, TimestampTz  lower, TimestampTz  upper, TimestampTz *  t1, TimestampTz *  t2  ) Return the TWO timestamps at which two temporal circular buffers segments are at the distance d. These are the turning points when computing the temporal distance. Parameters [in] start1,end1 Circular buffers defining the first segment [in] start2,end2 Circular buffers the second segment [in] dist Distance [out] lower,upper Timestamps defining the segments [out] t1,t2 Timestamps at turning points Precondition The segments are not constant.
