API docs

The libcurl docs state that numeric options should be longs:

Since curl_easy_setopt() is a vararg function where the 3rd argument can use different types depending on the situation, normal C language type conversion cannot be done. You must make sure that you truly pass a long and not an int if the documentation tells you so. -- https://everything.curl.dev/transfers/options/num.html

The docs also state that the CURLOPT_XFERINFOFUNCTION callback must match this prototype:

int xfer_callback(void *clientp, curl_off_t dltotal, curl_off_t dlnow,
                  curl_off_t ultotal, curl_off_t ulnow);
