However because the response is a success we ignore ++ *errnop and *h_errnop (though that means you touched errno on ++ success). We are being conservative here and returning the ++ likely IPv4 response in the first answer as a success. ++ ++ [2] If the first response is a recoverable TRYAGAIN we return ++ that instead of looking at the second response. The ++ expectation here is that we have failed to get an IPv4 response ++ and should retry both queries. ++ ++ [3] If the first response was not a SUCCESS and the second ++ response is not NOTFOUND (had a SUCCESS, need to TRYAGAIN, ++ or failed entirely e.g. TRYAGAIN' and UNAVAIL) then use the ++ result from the second response, otherwise the first responses ++ status is used. Again we have some odd side-effects when the ++ second response is NOTFOUND because we overwrite *errnop and ++ *h_errnop that means that a first answer of NOTFOUND might see ++ its *errnop and *h_errnop values altered. Whether it matters ++ in practice that a first response NOTFOUND has the wrong ++ *errnop and *h_errnop is undecided. ++ ++ [4] If the first response is UNAVAIL we return that instead of ++ looking at the second response. The expectation here is that ++ it will have failed similarly e.g. configuration failure. ++ ++ [5] Testing this code is complicated by the fact that truncated ++ second response buffers might be returned as SUCCESS if the ++ first answer is a SUCCESS.
