Guys. You talk very low-level libcurl talk. We have the curl-library mailing
list setup especially for that. You'll reach many more fellow libcurl
programmers there.
I'm cc'ing this reply over there and I trust you take follow-ups to that list
(only).

Hm. Would it suffice for your case if we made the iniy variable a true global?
Or do you have any other suggestions on how to fix this problem the best
