[collectd] Read callback return value

Suppose I have a read callback that isn't able to collect its data within a
given interval (e.g. operation times out). Do I have to return a non-zero
value in this case? What does that mean to the collectd engine?

Simply returning zero and not dispatching any values at all (via
plugin_dispatch_values()) seems to do no harm. So I'm curious what the
difference is between returning a a non-zero value and not dispatching any
