cbuffersegm_distance_turnpt() int cbuffersegm_distance_turnpt ( const Cbuffer *  start1, const Cbuffer *  end1, const Cbuffer *  start2, const Cbuffer *  end2, TimestampTz  lower, TimestampTz  upper, TimestampTz *  t1, TimestampTz *  t2  ) Return the TWO timestamps at which two temporal circular buffers segments are at the minimum distance. 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 [out] lower,upper Timestamps defining the segments [out] t1,t2 Timestamps at turning points Precondition The segments are not constant.
