+
+ <para><function>sd_journal_get_catalog()</function>
+ retrieves a message catalog entry for the current
+ journal entry. This will look up an entry in the
+ message catalog by using the
+ <literal>MESSAGE_ID=</literal> field of the current
+ journal entry. Before returning the entry all journal
+ field names in the catalog entry text enclosed in "@"
+ will be replaced by the respective field values of the
+ current entry. If a field name referenced in the
+ message catalog entry does not exist it the current
+ journal entry the "@" will be removed but the field
+ name otherwise left untouched.</para>
+
+ <para><function>sd_journal_get_catalog_for_message_id()</function>
+ works similar to
+ <function>sd_journal_get_catalog()</function> but the
+ entry is looked up by the specified message ID (no
+ open journal context is necessary for this), and no
+ field substitution is done.</para>
+
+ <para>For more information about the journal message
+ catalog please refer to the <ulink

+ Message Catalogs</ulink> documentation page.</para>
