+The function returns the error code @code{GPG_ERR_NO_ERROR} if a

+if the log specified in @var{flags} is not available for this engine.
+If no log is available @code{GPG_ERR_NO_DATA} is returned.

+Note: If log-file has been set in the configuration the log will
+be empty and @code{GPG_ERR_NO_DATA} will be returned.

+This flag has the value 0 for compatibility reasons.  Obtains additional
