tsequence_tagg() TSequence ** tsequence_tagg ( const TSequence **  sequences1, int  count1, const TSequence **  sequences2, int  count2, datum_func2  func, bool  crossings, int *  newcount  ) Generic aggregate function for temporal sequences. Parameters [in] sequences1 Accumulated state [in] count1 Number of elements in the accumulated state [in] sequences2 Sequences of a temporal sequence set [in] count2 Number of elements in the temporal sequence set [in] func Function, may be NULL for the merge aggregate function [in] crossings True if turning points are added in the segments [out] newcount Number of elements in the result Note Return new sequences that must be freed by the calling function.
