void somecallback(ev_loop *loop, ev_io *iowatch, int revents)
{
        write(iowatch->fd, "booya", 4);
        ev_io_stop(loop, iowatch);
}

main()

        ev_io iow;
        ev_loop *mainloop;
        
        fd = open("/dev/ttyS0", O_RDWR | O_NOCTTY | O_NONBLOCK);

        if(fd >= 0)
        {
                mainloop = ev_default_loop(EVFLAG_AUTO);
                ev_io_init(&iow, somecallback, fd, EV_WRITE);
                ev_io_start(mainloop, &iow);
                ev_run(mainloop, 0);
                close(fd);
        }
