A strict message loop is not the only option. Code elsewhere in the program can also accept and dispatch messages. PeekMessage is a non-blocking call that returns immediately, with a message if any are waiting, or no message if none is waiting. WaitMessage allows a thread to sleep until a message is in the queue.
The message queue paradigm is a sibling of the publisher/subscriber pattern, and is typically one part of a larger message-oriented middleware system. Most messaging systems support both the publisher/subscriber and message queue models in their API, e.g. Java Message Service (JMS).
Message queue: A data stream similar to a socket, but which usually preserves message boundaries. Typically implemented by the operating system, they allow multiple processes to read and write to the message queue without being directly connected to each other. Most operating systems Anonymous pipe
Java Message Service, similar technology on the Java platform; Amazon Simple Queue Service, commoditized messaging service provided by Amazon.com for a per-use fee. It allows users to rent access to messaging without having to maintain their own server. RabbitMQ, open source message queue broker that implements a pre-standard version of AMQP. [9]
Message pumps are said to 'pump' messages from the program's message queue (assigned and usually owned by the underlying operating system) into the program for processing. In the strictest sense, an event loop is one of the methods for implementing inter-process communication .
ZeroMQ (also spelled ØMQ, 0MQ or ZMQ) is an asynchronous messaging library, aimed at use in distributed or concurrent applications. It provides a message queue, but unlike message-oriented middleware, a ZeroMQ system can run without a dedicated message broker; the zero in the name is for zero broker. [3]
RabbitMQ is an open-source message-broker software (sometimes called message-oriented middleware) that originally implemented the Advanced Message Queuing Protocol (AMQP) and has since been extended with a plug-in architecture to support Streaming Text Oriented Messaging Protocol (STOMP), MQ Telemetry Transport (MQTT), and other protocols.
Messages stay in the queue until the time they are processed by a service consumer. Through the message queue, the application can be implemented independently - they do not need to know each other's position, or continue to implement procedures to remove the need for waiting to receive this message.
