Process data with a call back before the entire web page has been downloaded.

I am trying to process a lot of very large web pages and I need to
process some of the page before the entire page is downloaded.
Is there a way to get the call back function called before the entire
web page is downloaded?

My WriteMemoryCallback() function does not get called until the entire
page is loaded. We are doing weird stuff so this causes a big problem.

I am using curl 7.9 for Solaris.

    curl_easy_setopt(curl_handle, CURLOPT_URL, subdata[0]);
    curl_easy_setopt(curl_handle, CURLOPT_WRITEFUNCTION,
    curl_easy_setopt(curl_handle, CURLOPT_HEADER, 0);
    curl_easy_setopt(curl_handle, CURLOPT_FOLLOWLOCATION, 1);
    curl_easy_setopt(curl_handle, CURLOPT_USERAGENT, "KnowNow Curl

    /* get it! */
    res = curl_easy_perform(curl_handle);
