Abstract
A program routine generates Requests for a target system, such as a physical device or program code, to perform a service. Each Request includes identification information, and passes through intermediate layers, including a family program interface and a Family Server, for processing before it reaches the target system. The program routine also generates Cancels, which include the appropriate identification information, and sends the Cancels after the Requests. Each Cancel tracks its Request, and upon finding the Request, attempts to cancel it. A Cancel may find a Request before the Request has been forwarded to a target system, while it is being processed by the target system, after it has been executed by the target system, or may not find it. Results of the Requests and of the Cancels are returned through the intermediate layers to the program routine.
