Extern of varargs?

BlitzMax Forums/BlitzMax Programming/Extern of varargs?

So I am trying to wrap just the "easy" part of libcurl. I have to come up with a way to Extern this function:

CURL_EXTERN CURLcode curl_easy_setopt(CURL *curl, CURLoption option, ...);


In C, this function takes an option, then an arbitrary data type:

curl_easy_setopt(curl, CURLOPT_POST, 0); 
curl_easy_setopt(curl, CURLOPT_URL, "urlStr"); 
curl_easy_setopt(curl, CURLOPT_WRITEFUNCTION, curlData); 


How do you Extern varargs?
