NAME
ares_parse_a_reply - Parse a reply to a DNS query of type A
SYNOPSIS
#include <ares.h>
int ares_parse_a_reply(const unsigned char *abuf, int alen,
struct hostent **host,
struct ares_addrttl *addrttls, int *naddrttls);
DESCRIPTION
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 caller.
RETURN VALUES
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.
