.SH NAME
|
|
dns_name6_domain \- construct host name for reverse lookup
|
|
.SH SYNTAX
|
|
.B #include <dns.h>
|
|
|
|
void \fBdns_name6_domain\fP(char \fIq\fR[DNS_NAME6_DOMAIN],
|
|
const char* \fIip\fR[16],int \fItype\fR);
|
|
.SH DESCRIPTION
|
|
dns_name6_domain is a low-level component of dns_name6. It converts an
|
|
IP address such as 4321:0:1:2:3:4:567:89ab into a domain name such as
|
|
b.a.9.8.7.6.5.0.4.0.0.0.3.0.0.0.2.0.0.0.1.0.0.0.0.0.0.0.1.2.3.4.IP6.INT
|
|
and places the packet-encoded domain name into \fIq\fR.
|
|
|
|
\fItype\fR can be DNS_IP6_INT or DNS_IP6_ARPA. The "ip6.int" domain for
|
|
IPv6 reverse lookups is now deprecated and "ip6.arpa" is the standard
|
|
way.
|
|
|
|
q is zero terminated.
|
|
|
|
q must have space for DNS_NAME6_DOMAIN bytes.
