Function libafl_bolts::os::unix_signals::setup_signal_handler

pub unsafe fn setup_signal_handler<T: 'static + Handler>(
    handler: &mut T
) -> Result<(), Error>

Setup signal handlers in a somewhat rusty way. This will allocate a signal stack and set the signal handlers accordingly. It is, for example, used in LibAFL's InProcessExecutor to restart the fuzzer in case of a crash, or to handle SIGINT in the broker process.

Safety

The signal handlers will be called on any signal. They should (tm) be async safe. A lot can go south in signal handling. Be sure you know what you are doing.
