Manual Reference Pages - ARES_PARSE_A_REPLY (3)
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);
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
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 callers responsibility to free the resulting host structure
when it is no longer needed.
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 caller.
ares_parse_a_reply can return any of the following values:
The response was successfully parsed.
The response was malformatted.
The response did not contain an answer to the query.
Memory was exhausted.
