Detailed Description

The uIP DNS resolver functions are used to lookup a hostname and map it to a numerical IP address.

It maintains a list of resolved hostnames that can be queried with the resolv_lookup() function. New hostnames can be resolved using the resolv_query() function.

The event resolv_event_found is posted when a hostname has been resolved. It is up to the receiving process to determine if the correct hostname has been found by calling the resolv_lookup() function with the hostname.
