+B<RRDs::updatev> also returns a pointer to hash. The keys of the hash
+are concatenated strings of a timestamp, RRA index, and data source name for
+each consolidated data point (CDP) written to disk as a result of the
+current update call. The hash values are CDP values.
+
 B<RRDs::fetch> is the most complex of
 the pack regarding return values. There are 4 values. Two normal
 integers, a pointer to an array and a pointer to a array of pointers.
