+    <para>Functions that operate on the <structname>sd_journal</structname> object are thread
+    agnostic — given <structname>sd_journal</structname> pointer may only be used from one thread at
+    a time, but multiple threads may use multiple such objects safely. Other functions —
+    those that are used to send entries to the journal, like
+    <citerefentry><refentrytitle>sd_journal_print</refentrytitle><manvolnum>3</manvolnum></citerefentry>
+    and similar, or those that are used to retrieve global information like
+    <citerefentry><refentrytitle>sd_journal_stream_fd</refentrytitle><manvolnum>3</manvolnum></citerefentry>
+    and
+    <citerefentry><refentrytitle>sd_journal_get_catalog_for_message_id</refentrytitle><manvolnum>3</manvolnum></citerefentry>
