The pending flag is used by RTC_WKALM_RD to report a pending interrupt (so it's mostly useless on Linux, except when talking to the RTC man=E2=80=90 aged by EFI firmware). The time field is as used with RTC_ALM_READ and RTC_ALM_SET except that the tm_mday, tm_mon, and tm_year fields are also valid. A pointer to this struc=E2=80=90 ture should be passed as the third ioctl's argument. Implementation notes: All ioctls in this patch have pointer to a structure rtc_wkalrm as their third argument. That is the reason why corresponding definition is added in linux-user/syscall_types.h. Since all elements of this structure are either of type 'unsigned char' or 'struct rtc_time' (that was covered in one of previous patches), the rest of the implementation is straightforward.
