Notify a thread waiting on a change in the state of monitored data.
#include <prcmon.h> PRStatus PR_CNotify(void *address);
The function has the following parameter:
- The address of the monitored object. The calling thread must be in the monitor defined by the value of the address.
PR_SUCCESSindicates that the calling thread is the holder of the mutex for the monitor referred to by the address parameter.
PR_FAILUREindicates that the monitor has not been entered by the calling thread.
Using the value specified in the
address parameter to find a monitor in the monitor cache,
PR_CNotify notifies single a thread waiting for the monitor's state to change. If a thread is waiting on the monitor (having called
PR_CWait), then that thread is made ready. As soon as the thread is scheduled, it attempts to reenter the monitor.
