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 vari-
able 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.
