PR_NotifyAll
============
Promotes all threads waiting on a specified monitor to a ready state.
Syntax
------
.. code::
#include <prmon.h>
PRStatus PR_NotifyAll(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
-----------
A call to :ref:`PR_NotifyAll` causes all of the threads waiting on the
monitor to be scheduled to be promoted to a ready state. If no threads
are waiting, the operation is no-op.
:ref:`PR_NotifyAll` should be used with some care. The expense of
scheduling multiple threads increases dramatically as the number of
threads increases.
