EXAMPLE
       struct local {
         void *custom;
       };

       {
         struct local *l = userp;
         printf("my pointer: %p\n", l->custom);
         /* take care of the packet in 'ptr', then return... */
         return size * nmemb;
       }

       int main(void)
       {
         struct local rtp_data;
