Detailed Description
getdns uses an event loop abstraction layer to interface with event loop extensions. The extension accepts registration of getdns_eventloop_events and translates them to the underlying event loop API for which it is an extension. Also applications using getdns can use the abstraction layer themselves and in doing so inherit the flexibility being immediately compatible with all the event loop systems for which there is an extension already (i.e. libevent, libev and libuv).
