add io_block
make socket_(tc|ud)p[46] actually return non-blocking sockets as
documented (Richard Lyons)
fix for NetBSD 3.0 (Their /sys/types.h actually does not define u_char
unless you #define _NETBSD_SOURCE, and then their CMSG_* macros use
it. This is horrible even by OpenBSD standards)
remove support for ip6.int (it's no longer delegated)

@ -8,12 +8,9 @@ int \fBdns_name6\fP(stralloc* \fIout\fR,const char* \fIip\fR[16]);
.SH DESCRIPTION
dns_name6 looks up the domain name for the 16-byte IPv6 address in \fIip\fR. It
puts the (first) domain name into \fIout\fR and returns 0. If the relevant
ip6.int domain does not exist in DNS, or has no PTR records, \fIout\fR
ip6.arpa domain does not exist in DNS, or has no PTR records, \fIout\fR
will be empty.
dns_name6 will try both the new "ip6.arpa" reverse lookup domain and the
old (deprecated) "ip6.int" one.
If dns_name6 has trouble with the DNS lookup or runs out of memory, it returns
-1, setting errno appropriately. It may or may not change \fIout\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.
