I'm using an MPC885 with the linux kernel rtc emulator driver. Because I need 
to wake a process every second, exactly synchronized with the rtc, I'm using 
the following code 
snippet:<br><br>____________________________________________<br>/* Turn on 
update interrupts (one per second) */<br>retval = ioctl(fd, RTC_UIE_ON, 
0);<br>if (retval == -1) {<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 
perror("ioctl");<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 
exit(errno);<br>}<br><br>while 
(1)<br>{<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; /* This read will block 
*/<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; retval = read(fd, &amp;data, 
sizeof(unsigned long));<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; if 
(retval == -1) 
{<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
 
perror("read");<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
 exit(errno);<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 
}<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; /* Do something exactly synchronized 
with RTC */<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; /* ...... 
*/<br>}<br><br>_________________________________________<br><br><br>From time 
to time I receive the message on the subject. What's 
happening?<br><br><br>Bye,<br>Melinda.<br><br><p>&#32;
