+PR_Notify
+=========
+
+Notifies a monitor that a change in state of the monitored data has
+occurred.
+
+
+Syntax
+------
+
+.. code::
+
+   #include <prmon.h>
+
+   PRStatus PR_Notify(PRMonitor *mon);
+
+
+Parameters
+~~~~~~~~~~
+
+The function has the following parameter:
+
+``mon``
+   A reference to an existing structure of type :ref:`PRMonitor`. The
+   monitor object referenced must be one for which the calling thread
+   currently holds the lock.
+
+
+Returns
+~~~~~~~
+
+The function returns one of the following values:
+
+-  If successful, ``PR_SUCCESS``.
+-  If unsuccessful, ``PR_FAILURE``.
+
+
+Description
+-----------
+
+Notification of a monitor signals the change of state of some monitored
+data. The changing of that data and the notification must all be
+performed while in the monitor. When the notification occurs, the
+runtime promotes a thread that is waiting on the monitor to a ready
+state. If more than one thread is waiting, the selection of which thread
+gets promoted cannot be determined in advance. This implies that all
+threads waiting on a single monitor must have the same semantics. If no
+thread is waiting on the monitor, the notify operation is a no-op.
