[ldns-users] function call backs in ldns_resolver_send*?

How hard would it be to extend the ldns library with 2 new functions
that support callbacks? So to make asynchronous sending of queries
I was thinking about the following prototypes:
ldns_resolver_send_callback(cb_func, ldns_resolver *r, const
ldns_rdf *name, ldns_rr_type t, ldns_rr_class c, uint16_t flags);
ldns_resolver_send_pkt_callback(cb_func, ldns_resolver *r, ldns_pkt *query_pkt);
The cb_func prototype should be able to fill a ldns_pkt struct, so it
ldns_status cb_func(ldns_pkt *k)
I have never dealt with callback functions, so I don't know if this is
a viable proposal and how it impacts the rest of the ldns design.
