The third ioctl's' argument points to an int in which the voltage low is returned. RTC_VL_CLR - Clear voltage low information Clear the information about voltage low for RTCs that support voltage low. The third ioctl(2) argument is ignored. Implementation notes: Since one ioctl has a pointer to 'int' as its third agrument, and another ioctl has NULL as its third argument, their implementation was straightforward.
