 The :ref:`InterfaceRtemsInterruptGetAttributes` directive may be used to check
 if the processor affinity of an interrupt vector can be set.
 
+Only online processors of the affinity set specified by ``affinity_size`` and
+``affinity`` are considered by the directive.  Other processors of the set are
+ignored.  If the set contains no online processor, then the set is invalid and
+an error status is returned.
