示例1: notify
virtual void notify(SubscriptionId subid, const char *daliXpath, SDSNotifyFlags flags, unsigned valueLen, const void *valueData)
{
Linked<CDaliPackageWatcher> me = this; // Ensure that I am not released by the notify call (which would then access freed memory to release the critsec)
Linked<ISDSSubscription> myNotifier;
{
CriticalBlock b(crit);
if (traceLevel > 5)
DBGLOG("Notification on %s (%s), %p", xpath.get(), daliXpath ? daliXpath : "", this);
myNotifier.set(notifier);
// allow crit to be released, allowing this to be unsubscribed, to avoid deadlocking when other threads via notify call unsubscribe
}
if (myNotifier)
myNotifier->notify(subid, daliXpath, flags, valueLen, valueData);
