+ <para>A journal context object returned by
+ <function>sd_journal_open()</function> references a
+ specific journal entry as <emphasis>current</emphasis> entry,
+ similar to a file seek index in a classic file system
+ file, but without absolute positions. It may be
+ altered with
+ <citerefentry><refentrytitle>sd_journal_next</refentrytitle><manvolnum>3</manvolnum></citerefentry>
+ and
+ <citerefentry><refentrytitle>sd_journal_seek_head</refentrytitle><manvolnum>3</manvolnum></citerefentry>
+ and related calls. The current entry position may be
+ exported in <emphasis>cursor</emphasis> strings, as accessible
+ via
+ <citerefentry><refentrytitle>sd_journal_get_cursor</refentrytitle><manvolnum>3</manvolnum></citerefentry>. Cursor
+ strings may be used to globally identify a specific
+ journal entry in a stable way and then later to seek
+ to it (or if the specific entry is not available
+ locally, to its closest entry in time)
