_IMonitoringEvents Interface

An event source interface for managed and scripting clients.

You do not explicitly implement this interface. It is usually implemented by the language runtime. You register the so-called “events”, one for each method of this interface to handle specific monitored requests.

This interface is used by the managed and scripting clients. The language runtime usually uses the methods of this interface automatically, allowing the client to register the events, callbacks or delegates, which are called when the USB Monitoring Control library fires these events. There is a proprietary interface in each managed language to connect to event sources. You will see Microsoft C# examples in this documentation, for other languages, please consult their documentation for a proper syntax to handle events.
