Sample Code 

 /*
  Disables event notification and copies the previously used
  event mask to oldMask.  oldMask may then be used to re-enable
  event notification via another call to mpiNotifyEventMaskSet().
*/
  void NotifyDisable(MPINotify notify, MPIEventMask* oldMask)
{
    MPIEventMask newMask;
    int32_t returnValue;

    returnValue = mpiNotifyEventMaskGet(notify, oldMask);
    msgCheck(returnValue);

    mpiEventMaskCLEAR(newMask);

    returnValue = mpiNotifyEventMaskSet(notify, newMask);
    msgCheck(returnValue);
