You know if the dns resolution has completed because either: - dns_gethostbyname() returns ERR_OK; or - the callback function given to dns_gethostbyname() is called. It sounds like you want to know after calling dns_gethostbyname() whether or not the callback has been called yet. The way to solve this would be to modify some state from the callback and you can then use that state to tell if the callback has been called.
