cs_dt_info() a NOOP?

Hello,

According to http://www.freetds.org/userguide/ctlib.api.summary.htm:

	Category	Function	Status	Comments
	(all)		cs_dt_info	OK		Set or retrieve
language-specific datetime information.

However, from src/ctlib/cs.c:

  CS_RETCODE
  cs_dt_info(CS_CONTEXT * ctx, CS_INT action, CS_LOCALE * locale, CS_INT
type, CS_INT item, CS_VOID * buffer, CS_INT buflen,
           CS_INT * outlen)
  {
        if (action == CS_SET) {
                switch (type) {
                case CS_DT_CONVFMT:
                        break;
                }
        }
        return CS_SUCCEED;
  }

Hmm ... that doesn't seem to do much :-).  At a minimum, shouldn't the
API summary doc reflect this?  David
