+        - The task has no priority within the specified scheduler instance.
+          This error is only possible in SMP configurations.
+
+DESCRIPTION:
+    This directive returns the current priority of the task specified by
+    :c:data:`task_id` with respect to the scheduler instance specified by
+    :c:data:`scheduler_id`.  A task id of :c:macro:`RTEMS_SELF` is used to
+    indicate the calling task.
+
+NOTES:
+    The current priority reflects temporary priority adjustments due to locking
+    protocols, the rate-monotonic period objects on some schedulers and other
+    mechanisms.
