> On occasion it might be useful to determine which host your Zookeeper client is currently connected to, be it for debugging purposes or otherwise. A possible signature for that function:
> const char* zoo_get_connected_host(zhandle_t *zh, char *buffer, size_t buffer_size, unsigned short *port);
> Clients could use it like below:
>   char buffer[33];
>   unsigned short port = 0;
>   if (!zoo_get_connected_host(zh, buffer, sizeof(buffer), &port))
>     return EXIT_FAILURE;
>   printf("The connected host is: %s:%d\n", buffer, port);
