ares_parse_a_reply - Parse a reply to a DNS query of type A
int ares_parse_a_reply(const unsigned char *abuf, int alen,
struct hostent **host,
struct ares_addrttl *addrttls, int *naddrttls);
The ares_parse_a_reply function parses the response to a query of type A into a struct
hostent and/or an array of struct ares_addrttls. The parameters abuf and alen give the
contents of the response. The result is stored in allocated memory and a pointer to it
stored into the variable pointed to by host, if host is nonnull. It is the caller's
responsibility to free the resulting host structure using ares_free_hostent(3) when it is
no longer needed.
If addrttls and naddrttls are both nonnull, then up to *naddrttls struct ares_addrttl
records are stored in the array pointed to by addrttls, and then *naddrttls is set to the
number of records so stored. Note that the memory for these records is supplied by the
ares_parse_a_reply can return any of the following values:
ARES_SUCCESS The response was successfully parsed.
ARES_EBADRESP The response was malformatted.
ARES_ENODATA The response did not contain an answer to the query.
ARES_ENOMEM Memory was exhausted.
