+ * Alternate update interface, updatev. Returns info about CDPs written to disk as result of update. Output format is similar to rrd_info, a hash of key-values.

* Revision 1.8 2003/03/31 21:22:12 oetiker
* enables RRDtool updates with microsecond or in case of windows millisecond
* precision. This is needed to reduce time measurement error when archive step
