These are my callback functions.

*stream)

    curl_off_t nread;
    /* in real-world cases, this would probably get this data differently
       as this fread() stuff is exactly what the library already would do
       by default internally */
    size_t retcode = fread(ptr, size, nmemb, (FILE*)stream);

    nread = (curl_off_t)retcode;

    fprintf(stderr, "*** We read %" CURL_FORMAT_CURL_OFF_T
        " bytes from file\n", nread);
    return retcode;
}

size_t write_callback(char *ptr, size_t size, size_t nmemb, void *userdata)
{
    return size * nmemb;
}
