ares_parse_ptr_reply(3) Library Functions Manual ares_parse_ptr_reply(3)
NAME
ares_parse_ptr_reply - Parse a reply to a DNS query of type PTR into a
hostent
SYNOPSIS
#include <ares.h>
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 struct hostent. The parameters abuf and alen give the
contents of the response. The parameters addr, 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 struct hostent.
The resulting struct hostent is stored in allocated memory and a
pointer to it stored into the variable pointed to by 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.
