RequestCallback
A callback invoked when a request is ready.
The parameter request
holds the request’s content in a
RequestResult structure.
The userData

(see SubscribeRequest(String,RequestCallback,IntPtr)).
Any memory held by the RequestResult is invalidated when the callback returns.
Parameters
request : RequestResult : A RequestResult structure containing the request content.
userData : IntPtr : IntPtr value set with SubscribeRequest(String,RequestCallback,IntPtr).
