Functions
: Name to look up
dns_query - Query the DNS : Query type (or NULL for straight host->IP lookup) : Length of name : Request options (or NULL if no options) : Where to place the returned data. : Where to store the result expiry time (or NULL) The data will be returned in the pointer at *result, and the caller is responsible for freeing it. The description should be of the form "[<query_type>:]<domain_name>", and the options need to be appropriate for the query type requested. If no query_type is given, then the query is a straight hostname to IP address lookup. The DNS resolution lookup is performed by upcalling to userspace by way of requesting a key of type dns_resolver. Returns the size of the result on success, -ve error code otherwise.
