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.

DEFAULT

       NULL

PROTOCOLS

       This functionality affects rtsp only

EXAMPLE

       int main(void)
       {
         CURL *curl = curl_easy_init();
         if(curl) {
           CURLcode res;
           char *prev_id; /* 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);
         }
       }
