Title: Rtc Alarm Not Worked In Rc 10
Post by: SSG on May 27, 2005, 03:30:05 am

Hi dear All!

   int fd, retval;
   unsigned long  data;
   struct rtc_time rtc_tm;

   /* Open runtime clock device */
   fd = open ("/dev/rtc", O_RDONLY);
      
    /* Enable alarm interrupts */
   retval = ioctl(fd, RTC_AIE_ON, 0);

   /* This blocks until the alarm ring causes an interrupt */
   retval = read(fd, &data, sizeof(unsigned long));

In RC9 this code wakeup my Zaurus from suspend mode in given time, in RC10 this not worked - why?

what is returned by  open ("/dev/rtc", O_RDONLY); ?

Maybe the /dev/rtc is opened by something else?

(I read something about this somewhere but I can't remember where;)
like hwclock called before etc..)

Oh if you are into this you might be intersted in this version of the atd daemon :

After installing nntp it's worked. I see later why.
