# SignalRaise
<span class="source-link">[[Source]](src/signals/signal_notify.md#L-0-70)</span>

Raise a signal.

Unlike SignalHandler, this accepts a raw signal number rather than a
HandleableSignal. Raising fatal signals (e.g. SIGABRT to intentionally crash)
is a legitimate operation — it is only handling them via the ASIO
mechanism that is prevented.

The raise is process-wide: every currently subscribed handler for the
signal is notified. With no subscribers, the signal's current disposition
applies — the operating system default for most signals (process death for
a terminating one), but SIG_IGN for one the runtime keeps ignored like
SIGPIPE.
