Method of transmitting messages between software processes in a multitasking data processing system

摘要

In a data processing system that includes operating system software with a messaging capability, a method of transmitting a message between software processes includes a message clearing house that (a) receives a message transmittal request from a sending process; (b) generates a header for the message in accordance with the operating system's requirements; said header includes information indicating the time at which the request is received, and said header is stored in a circular buffer to facilitate debugging; (c) determines an exchange address for the process that is to receive the message; and (d) transmits the message via the operating system to the exchange address of the receiving process.
