NAME

ares_parse_aaaa_reply - Parse a reply to a DNS query of type AAAA

SYNOPSIS

 #include <ares.h>
 
 int ares_parse_aaaa_reply(const unsigned char *abuf, int alen,
 struct hostent **host,         
 struct ares_addr6ttl *addrttls, int *naddrttls);
 

DESCRIPTION

The ares_parse_aaaa_reply function parses the response to a query of type AAAA into a struct hostent and/or an array of struct ares_addr6ttl. 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_addr6ttl 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_aaaa_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.
