Hey,

I think I finally got it done. Here is the part of the code:

// DownloadStruct should contain:

// time_t myTime

// curl_off_t myWriteCount

// Should be initialized to 0 before given to the callback.

int callback(char *data, unsigned int size, unsigned int nmemb, struct
DownloadStruct *ptr)

{

    int result = 0;

    if (ptr)

    {

        result = size * nmemb;

        // write to file...

        double div = difftime(time(0), ptr->myTime);

        if (div >= 1)

        {

            double speed = ptr->myWriteCount / div;

            speed /= 1024; // kilobytes per second

            // do something with speed

            ptr->myWriteCount = 0;

            ptr->myTime = time(0);

        }

        else

        {

            ptr->myWriteCount += result;

        }

    }

    return result;

}

I think that should work very well. Thank you very much for the help :)

Patrick K.
