CURLOPT_INTERLEAVEDATA3

Usage

#include <curl/curl.h>
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_INTERLEAVEDATA, void *pointer);

Overview

This is the userdata pointer that is passed to CURLOPT_INTERLEAVEFUNCTION(3) when interleaved RTP data is received. If the interleave function callback is not set, this pointer is not used anywhere.

Default

NULL

Protocols

This functionality affects rtsp only

Examples

struct local {
  void *custom;
};
static size_t rtp_write(void *ptr, size_t size, size_t nmemb, void *userp)
{
  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;
  CURL *curl = curl_easy_init();
  if(curl) {
    CURLcode result;
    curl_easy_setopt(curl, CURLOPT_INTERLEAVEFUNCTION, rtp_write);
    curl_easy_setopt(curl, CURLOPT_INTERLEAVEDATA, &rtp_data);
    result = curl_easy_perform(curl);
    curl_easy_cleanup(curl);
  }
}

Return value

curl_easy_setopt(3) returns a CURLcode indicating success or error.

CURLE_OK (0) means everything was OK, non-zero means an error occurred, see libcurl-errors(3).
