COMMUNICATION USING A MESSAGE QUEUE

摘要

A method of communicating between a source (14) and a destination (12) uses a message queue (16) which is common to the source (14) and the destination (12). The method includes placing a message from the source (14) intended for the destination (12) in the message queue (16), retrieving the message from the message queue (16) at the destination (12) and preventing execution of a message placed in the message queue (16) prior to the retrieved message if the retrieved message invalidates the prior message.
