+==========
+
+Notify a thread waiting on a change in the state of monitored data.
+
+
+Syntax
+------
+
+.. code::
+
+   #include <prcmon.h>
+
+   PRStatus PR_CNotify(void *address);
+
+
+Parameter
+~~~~~~~~~
+
+The function has the following parameter:
+
+``address``
+   The address of the monitored object. The calling thread must be in
+   the monitor defined by the value of the address.
+
+
+Returns
+~~~~~~~
+
+ - :ref:`PR_SUCCESS` indicates that the calling thread is the holder of the
+   mutex for the monitor referred to by the address parameter.
+ - :ref:`PR_FAILURE` indicates that the monitor has not been entered by the
+   calling thread.

+
+Description
+-----------
+
+Using the value specified in the ``address`` parameter to find a monitor
+in the monitor cache, :ref:`PR_CNotify` notifies single a thread waiting
+for the monitor's state to change. If a thread is waiting on the monitor
+(having called :ref:`PR_CWait`), then that thread is made ready. As soon as
+the thread is scheduled, it attempts to reenter the monitor.
