CURLINFO_RTSP_SESSION_ID explained

Name

CURLINFO_RTSP_SESSION_ID - get RTSP session ID

Synopsis

#include <curl/curl.h>
 
CURLcode curl_easy_getinfo(CURL *handle, CURLINFO_RTSP_SESSION_ID, char **id);

Description

Pass a pointer to a char pointer to receive a pointer to a string holding the most recent RTSP Session ID.

Applications wishing to resume an RTSP session on another connection should retrieve this info before closing the active connection.

The id pointer is NULL or points to private memory. You MUST NOT free - it gets freed when you call curl_easy_cleanup on the corresponding CURL handle.

Protocols

This functionality affects rtsp only

Example

int main(void)
{
  CURL *curl = curl_easy_init();
  if(curl) {
    CURLcode res;
    curl_easy_setopt(curl, CURLOPT_URL, "rtsp://rtsp.example.com");
    res = curl_easy_perform(curl);
    if(res == CURLE_OK) {
      char *id;
      curl_easy_getinfo(curl, CURLINFO_RTSP_SESSION_ID, &id);
    }
    curl_easy_cleanup(curl);
  }
}
