You're quite right.  But I'm only as confused as the code is.  

I was trying to catch the return from tds_process_param_result(), which
can be a token *or* TDS_FAIL.  But of course the logic:

        while ((marker = tds_get_byte(tds)) == TDS_PARAM_TOKEN) {
                tds_process_param_result(tds, pinfo);
        }

ignores the return code and discards the token.  I'm surprised it works.
