for an example how to iterate through the journal

+
+ A journal context object returned by
+ sd_journal_open() references a
+ specific journal entry as current entry,
+ similar to a file seek index in a classic file system
+ file, but without absolute positions. It may be
+ altered with
+ sd_journal_next3
+ and
+ sd_journal_seek_head3
+ and related calls. The current entry position may be
