| typedef typedefISC_LANG_BEGINDECLS struct dig_lookup | dig_lookup_t |
| Lookup_limit is just a limiter, keeping too many lookups from being created. It's job is mainly to prevent the program from running away in a tight loop of constant lookups. It's value is arbitrary. | |

| Clone a lookup, perhaps copying the server list. This does not clone the query list, since it will be regenerated by the setup_lookup() function, nor does it queue up the new lookup for processing. Caution: If you don't clone the servers, you MUST clone the server list separately from somewhere else, or construct it by hand. | |
