-                    the output when an error has occurred.
+        Arguments:
+        - `status`: status string like "200 OK" or integer status code.
+        - `response_headers`: list of (field, value) tuples.
+        - `exc_info`: optional exception info; if headers already sent, re-raise.
 
-                    However, if exc_info is provided, and the HTTP headers
-                    have already been sent, start_response must raise an error,
-                    and should re-raise using the exc_info tuple. That is:
