.SH DESCRIPTION
|
|
The
|
|
.B ares_parse_aaaa_reply
|
|
function parses the response to a query of type AAAA into a
|
|
.BR "struct hostent"
|
|
and/or an array of
|
|
.BR "struct addr6ttl" .
|
|
The parameters
|
|
.I abuf
|
|
and
|
|
.I 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
|
|
.IR host ,
|
|
if host is nonnull.
|
|
It is the caller's responsibility to free the resulting host structure
|
|
using
|
|
.BR ares_free_hostent (3)
|
|
when it is no longer needed.
|
|
.PP
|
|
If
|
|
.IR addrttls
|
|
and
|
|
.IR naddrttls
|
|
are both nonnull,
|
|
then up to *naddrttls
|
|
.BR "struct 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.
|
|
