+ <para><function>sd_journal_open_files()</function>
+ is similar to <function>sd_journal_open()</function>
+ but takes a <constant>NULL</constant>-terminated list
+ of file paths to open. All files will be opened and
+ interleaved automatically. This call also takes a
+ flags argument, but it must be passed as 0 as no flags
+ are currently understood for this call. Please note
+ that in the case of a live journal, this function is only
+ useful for debugging, because individual journal files
+ can be rotated at any moment, and the opening of
+ specific files is inherently racy.</para>
+
+ <para><varname>sd_journal</varname> objects cannot be
+ used in the child after a fork. Functions which take a
+ journal object as an argument
+ (<function>sd_journal_next()</function> and others)
+ will return <constant>-ECHILD</constant> after a fork.
