[Abdul Basit <basit@xxxxxxxx>]

I tried to use getnameinfo

----
     host is char buf[NI_MAXHOST];

     for(;;) {

         slen  = res->ai_addrlen;
         ptr1  = malloc(sizeof(int));
         *ptr1 = accept(listenfd, caddr,  &slen);

        if((k=getnameinfo(res->ai_addr,res->ai_addrlen,buf,sizeof(buf),NULL,0,NI_NAMEREQD)) <0) {
            printf("%s\n",gai_strerror(k));
        }
     }

it prints:

buf = |

? any help
I saw
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/winsock/winsock/ipv6_enabled_server_code_2.asp

they are using multiple listenfds to handle this ?
