What you need to do is put those into your own structure, and then pass
a pointer to that.

So something like the following...

// amongst everything else, you'd get
// "a is 10, b is 1337"

typedef struct {
    int a, b;
    // other stuff
} myStruct;

size_t my_write_data(void *ptr, size_t size, size_t nmemb, void *stream)
{
    myStruct *myData;
    myData = (myStruct *)stream;

    printf("a is %d, b is %d", myData->a, myData->b);

    // everything else ...
}

main(..) {
    .....

  MyStruct dat;
  dat.a = 10;
  dat.b = 1337;

 curl_easy_setopt(curlHandle, CURLOPT_WRITEFUNCTION, my_write_data);
 curl_easy_setopt(curlHandle, CURLOPT_FILE, &dat);

 /* get it! */
 curl_easy_perform(curlHandle);

  .....
}
