Overview​

ripple allows you to listen to system signals through the onSignal method and execute the specified closure function when the signal is triggered.

Basic usage​

\Co\onSignal(SIGINT, function () {

    exit(0);
});

After registering any signal handler, if the signal handler is not canceled correctly, \Co\wait will consider that there are unfinished events and will wait until all events are completed.
