NAME
ares_parse_ptr_reply - Parse a reply to a DNS query of type PTR into a hostent
SYNOPSIS
int ares_parse_ptr_reply(const unsigned char *abuf, int alen,
const void *addr, int addrlen, int family,
struct hostent **host);
DESCRIPTION
The
ares_parse_ptr_reply
function parses the response to a query of type PTR into a
R struct hostent .
The parameters
abuf
and
alen
give the contents of the response. The parameters
R addr ,
R addrlen ,
and
family
specify which address was queried for; they are not used to verify the
response, merely used to fill in the address of the
R struct hostent .
The resulting
struct hostent
is stored in allocated memory and a pointer to it stored into the
variable pointed to by
R host .
It is the caller's responsibility to free the resulting host structure
using
ares_free_hostent(3)
when it is no longer needed.
RETURN VALUES
ares_parse_ptr_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.
