According to the documentation you must provide a *pointer* to that
function.
http://curl.haxx.se/libcurl/c/curl_easy_setopt.html#CURLOPTWRITEFUNCTION

I am not a c++ coder myself but as far as i can see you are referencing a
variable there that doesnt exist. Dont you get compiler errors when you try
to compile that?

In the language I use I use a function called "RegisterCallback( )" to get
the call back pointer needed for that option, in c++ there is a similar
function i assume so you might want to do something like:

rCallBack = registercallback(<func params here>);

and then pass var to setopt, like:

curl_easy_setopt(curl, CURLOPT_WRITEFUNCTION, rCallBack);

Again I am not a c++ coder but thats how i assume it should be, because
thats how i do it in my language.
