Notifies all the threads waiting for a change in the state of monitored data.


#include <prcmon.h> 

PRStatus PR_CNotifyAll(void *address);


The function has the following parameter:

The address of the monitored object. The calling thread must be in the monitor at the time PR_CNotifyAll is called.


  • PR_SUCCESS indicates that the referenced monitor was located and the calling thread was in the monitor.
  • PR_FAILURE indicates that the referenced monitor could not be located or that the calling thread was not in the monitor


Using the value specified in the address parameter to find a monitor in the monitor cache, PR_CNotifyAll notifies all threads waiting for the monitor's state to change. All of the threads waiting on the state change are then scheduled to reenter the monitor.
