tinstant_tagg() TInstant ** tinstant_tagg ( TInstant **  instants1, int  count1, TInstant **  instants2, int  count2, datum_func2  func, int *  newcount, void ***  tofree, int *  nfree  ) Generic aggregate function for temporal instants. Parameters [in] instants1 Instants of the accumulated state that overlap with the new instants in instants2. At this point of the processing these instants have been removed from the skiplist. [in] instants2 Instants of the input temporal discrete sequence that need to be merged into the skiplist. [in] count1,count2 Number of values in the input arrays [in] func Function, may be NULL for the merge aggregate function [out] newcount Number of instants in the output array [out] tofree Array of values that must be freed [out] nfree Number of values that must be freed
