Please document that the res_search function return the *actual* length

thanks

Does this bug still apply?  The relevant section says:

       The res_query(),  res_search(),  res_querydomain(),
       res_mkquery()  and res_send()  functions  return  the  length
       of the response, or -1 if an error occurs.

Which seems accurate to me.

It is ambiguous.  Does "length of the response" refer to the number of
bytes actually written, or the number of bytes received?
