+          array of file descriptors for files that contain FFDC (first failure
+          data capture) data which may be used by event log extensions that
+          support storing it with their event logs.  The other arguments are
+          the same as with Create().  The FFDC argument is ignored by the
+          base phosphor-logging event logs.
+
+          When the method call is complete the descriptors must be closed and
+          the files can be deleted if desired.
