16 The ares_parse_a_reply function parses the response to a query of type
17 A into a struct hostent. The parameters abuf and alen give the con‐
18 tents of the response. The result is stored in allocated memory and a
19 pointer to it stored into the variable pointed to by host. It is the
20 caller's responsibility to free the resulting host structure using
21 ares_free_hostent(3) when it is no longer needed.
22
24 ares_parse_a_reply can return any of the following values:

26 ARES_SUCCESS The response was successfully parsed.
27
28 ARES_EBADRESP The response was malformatted.
29
30 ARES_ENODATA The response did not contain an answer to the query.
31
32 ARES_ENOMEM Memory was exhausted.
