Provides a messaging layer overtop of a stream implementation based on IG Stream Base. Allows using a single communication stream to send multiple messages identified by a string. VI Callbacks are the mechanism used to process incoming messages which allow the developer to choose whether the message gets forwarded by events, queues, notifiers, or some other means.

Messages can be sent to all currently connected endoints (broadcasting) via the messaging manager or to specific endpoints by sending to a specific endpoint instance. Callbacks can also be registered to handle new connections or disconnections. Each endpoint runs in its own asynchronous messaging loop to take advantage of multi-threading and run without polling behaviors for efficiency.

Examples for this library are provided in the IG Simple Msg Examples package and also depend on IG TCP Stream as they use TCP streaming to communicate between parts of the examples. An example is included for basic data streaming from a data producer and a display. Another example is an updated chat application that provides more features than the chat example included with the TCP Stream package.
