[reSIProcate] Dealing with callback functions?

["Dien Ba Quang" <dienbaquang@xxxxxxxxx>]

Hi,
I'm trying to wrap resiprocate into a dll, but i have a problem with
resiprocate callback functions. Now, I implemented all resiprocate
callback functions(register, subscribe, invite handler,...) into dll
and using callback function to notify (exe application). My
implementation doesn't look good (messy code).
Do you know any good way to notify the application(exe app) from dll?

Any help would be appreciated.

DBQ.
