Example #1

File: vibrator.c Project: garyhsh/hardware

int vibrator_exists()
{
    int fd;

#ifdef QEMU_HARDWARE
    if (qemu_check()) {
        return 1;
    }
#endif

    fd = open(THE_DEVICE, O_RDWR);
    if(fd < 0)
        return 0;
    close(fd);
    return 1;
}

Example #2

File: vibrator.c Project: garyhsh/hardware

{
    int nwr, ret, fd;
    char value[20];

#ifdef QEMU_HARDWARE

    }
#endif

    fd = open(THE_DEVICE, O_RDWR);
    if(fd < 0)
        return errno;

    timeout_ms = timeout_ms * 3;

    ret = write(fd, value, nwr);

    close(fd);

    return (ret == nwr) ? 0 : -1;
}
