struct local {

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

int main(void)
{
  struct local rtp_data;
  CURL *curl = curl_easy_init();
  if(curl) {
    curl_easy_setopt(curl, CURLOPT_INTERLEAVEFUNCTION, rtp_write);
    curl_easy_setopt(curl, CURLOPT_INTERLEAVEDATA, &rtp_data);
