CURLOPT_INTERLEAVEDATA(3)  Library Functions Manual  CURLOPT_INTERLEAVEDATA(3)

NAME
       CURLOPT_INTERLEAVEDATA - pointer passed to RTSP interleave callback

SYNOPSIS
       #include <curl/curl.h>

       CURLcode curl_easy_setopt(CURL *handle, CURLOPT_INTERLEAVEDATA, void *pointer);

DESCRIPTION
       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

EXAMPLE
       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) {
           curl_easy_setopt(curl, CURLOPT_INTERLEAVEFUNCTION, rtp_write);
           curl_easy_setopt(curl, CURLOPT_INTERLEAVEDATA, &rtp_data);

           curl_easy_perform(curl);
        }
       }
