MQ4CPP - Message queueing for C++ MQ4CPP (Message Queuing for C++) is an implementation of enterprise messaging system, aka "message-oriented middleware" (MOM). It lets C++ application threads communicate with one another through exchanging messages. A message is a request, report, and/or event that contains information needed to coordinate communication between different applications. It provides a level of abstraction, so you can separate the details about the destination system from the application code.
MQ4CCP lets C++ applications that share a messaging system exchange messages, and simplifies application development by providing a standard interface for creating, sending, and receiving messages. It implements the following messaging paradigms: Direct/Indirect messaging (local), unsolicited messaging (remote), Request/Reply (remote), conversation (remote), and broadcast (local/remote).
