#Member Function Documentation

#[static] KSignalHandler *KSignalHandler::self()

Fetches an instance we can use to register our signals.

#[signal] void KSignalHandler::signalReceived(int signal)

Notifies that signal is emitted.

To catch a signal, we need to make sure it's registered using @m watchSignal.

See also watchSignal

#void KSignalHandler::watchSignal(int signal)

Adds signal to be watched for. Once the process is notified about this signal, @m signalReceived will be emitted with the same signal as an argument.
