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.

This technically violates best practice ++ since the server is allowed to read the first query, respond, and ++ then close the socket (to service another client). If the server ++ does this, then the remaining second query in the socket data buffer ++ will cause the server to send the client an RST which will arrive ++ asynchronously and the client's OS will likely tear down the socket ++ receive buffer resulting in a potentially short read and lost ++ response data. This will force the client to retry the query again, ++ and this process may repeat until all servers and connection resets ++ are exhausted and then the query will fail. It's not known if this ++ happens with any frequency in real DNS server implementations. This ++ implementation should be corrected to use two sockets by default for ++ parallel queries. ++ ++ The query stored in BUF of BUFLEN length is sent first followed by ++ the query stored in BUF2 of BUFLEN2 length.

If more than *ANSSIZP bytes are needed and ANSCP ++ is non-NULL (to indicate that modifying the answer buffer is allowed) ++ then malloc is used to allocate a new response buffer and ANSCP and ++ ANSP will both point to the new buffer. If more than *ANSSIZP bytes ++ are needed but ANSCP is NULL, then as much of the response as ++ possible is read into the buffer, but the results will be truncated. ++ When truncation happens because of a small answer buffer the DNS ++ packets header feild TC will bet set to 1, indicating a truncated ++ message and the rest of the socket data will be read and discarded. ++ ++ Answers to the query are stored secondly in *ANSP2 up to a max of ++ *ANSSIZP2 bytes, with the actual response length stored in ++ *RESPLEN2.

It also supports serial lookup ++ with a close and reopen of the socket used to talk to the server ++ (RES_SNGLKUPREOP) to work around broken name servers. ++ ++ The query stored in BUF of BUFLEN length is sent first followed by ++ the query stored in BUF2 of BUFLEN2 length.
