+ * NAME
+ * plugin_dispatch_multivalue
+ *
+ * SYNOPSIS
+ * plugin_dispatch_multivalue (vl, 1,
+ * "free", 42.0,
+ * "used", 58.0,
+ * NULL);
+ *
+ * DESCRIPTION
+ * Takes a list of type instances and values and dispatches that in a batch,
+ * making sure that all values have the same time stamp. If "store_percentage"
+ * is set to true, the "type" is set to "percent" and a percentage is
+ * calculated and dispatched, rather than the absolute values. Values that are
+ * NaN are dispatched as NaN and will not influence the total.
+ *
+ * The variadic arguments is a list of type_instance / gauge pairs, that are
+ * interpreted as type "char const *" and "gauge_t". The last argument must be
+ * a NULL pointer to signal end-of-list.
+ *
+ * RETURNS
+ * The number of values it failed to dispatch (zero on success).
