Zusammenfassung:A processor receives a signal and determines whether an application has registered a signal handler therewith for handling the signal. In response to determining that the application has registered the signal handler, the processor transmits the signal directly to the signal handler of the application for handling the signal, without an operating system in relation to which the trusted application is running intervening. In response to determining that the trusted application has not registered the signal handler, the processor transmits the signal to a signal handler of the operating system for handling the signal.
