Abstract
An operating system is simulated to run in conjunction with a native operating system, allowing processes originally developed for the operating system being simulated to be ported to the environment of the native operating system with a minimum of effort. In the event a ported process attempts to communicate with a terminated process before the simulated operating system is notified of the termination, the attempt at communication will return an error. In response, a series of checks are performed to determine if the error was the result of termination of the process with which communication was attempted, or a more serious error that should be reported to the native operating system for action to protect the integrity of data.
