Add a notifier to the plugin manager.
The call back function is executed just after loading, or just after unloading, a plugin.
To use define: PDECLARE_NOTIFIER(PDynaLink, YourClass, YourFunction); and void YourClass::YourFunction(PDynaLink & dll, INT code) { code == 0 means loading code == 1 means unloading } and to connect to the plugin manager: PPluginManager & mgr = PPluginManager::GetPluginManager(); mgr->AddNotifier((PCREATE_NOTIFIER(YourFunction));
