+
+This alternate version of B<update> takes the same arguments and
+performs the same function. The I<v> stands for I<verbose>, which
+describes the output returned. B<updatev> returns a list of any and all
+consolidated data points (CDPs) written to disk as a result of the
+invocation of update. The values are indexed by timestamp (time_t),
+RRA (index number), and data source (name). Note that depending
+on the arguments of the current and previous call to update, the
+list may have no entries or a large number of entries.
+
=item I<filename>
The name of the B<RRD> you want to update.
