NAME

       dns_name6 - look up host name

SYNTAX

       #include <dns.h>

       int dns_name6(stralloc* out,const char* ip[16]);

DESCRIPTION

       dns_name6  looks  up  the domain name for the 16-byte IPv6 address in ip. It puts the (first) domain name
       into out and returns 0. If the relevant ip6.arpa domain does not exist in DNS, or has no PTR records, out
       will be empty.

       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 out.
