You want _Exit() instead. exit() will call atexit() handlers which will are likely not signal-safe. And you probably want to use fd 2 (stderr), instead of fd 1 in the write() call. That said: if you're not going to add any more info in your signal handler, or do any cleanup like unlink() files, it may just be best to let it crash and generate a crash log.
