PR_NotifyAllCondVar
===================
Notifies all of the threads waiting on a specified condition variable.
Syntax
------
.. code::
#include <prcvar.h>
PRStatus PR_NotifyAllCondVar(PRCondVar *cvar);
Returns
~~~~~~~
The function returns one of the following values:
- If successful, ``PR_SUCCESS``.
- If unsuccessful (for example, if the caller has not locked the lock
associated with the condition variable), ``PR_FAILURE``.
Description
-----------
The calling thread must hold the lock that protects the condition, as
well as the invariants that are tightly bound to the condition.
A call to :ref:`PR_NotifyAllCondVar` causes all of the threads waiting on
the specified condition variable to be promoted to a ready state. If no
threads are waiting, the operation is no-op.
