NAME

       CURLOPT_RTSP_SESSION_ID - RTSP session ID

SYNOPSIS

       #include <curl/curl.h>

       CURLcode curl_easy_setopt(CURL *handle, CURLOPT_RTSP_SESSION_ID, char *id);

DESCRIPTION

       Pass a char pointer as a parameter to set the value of the current RTSP Session ID for the handle. Useful
       for  resuming  an  in-progress  session.  Once  this  value is set to any non-NULL value, libcurl returns
       CURLE_RTSP_SESSION_ERROR if ID received from the server does not  match.  If  unset  (or  set  to  NULL),
       libcurl automatically sets the ID the first time the server sets it in a response.

       The application does not have to keep the string around after setting this option.

       Using  this option multiple times makes the last set string override the previous ones. Set it to NULL to
       disable its use again.

DEFAULT

       NULL

PROTOCOLS

       This functionality affects rtsp only

EXAMPLE

       int main(void)
       {
         CURL *curl = curl_easy_init();
         if(curl) {
           CURLcode res;
           char *prev_id = "old"; /* saved from before somehow */
           curl_easy_setopt(curl, CURLOPT_URL, "rtsp://example.com/");
           curl_easy_setopt(curl, CURLOPT_RTSP_SESSION_ID, prev_id);
           res = curl_easy_perform(curl);
           curl_easy_cleanup(curl);
         }
       }
