Syntax

#include <prcmon.h> 

PRStatus PR_CNotify(void *address);

Parameter

The function has the following parameter:

address

Returns

  • PR_SUCCESS indicates that the calling thread is the holder of the mutex for the monitor referred to by the address parameter.
  • 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, PR_CNotify notifies single a thread waiting for the monitor's state to change.
