NAME
       CURLOPT_RTSP_SESSION_ID - set RTSP session ID

SYNOPSIS
       #include <curl/curl.h>

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

DESCRIPTION
       Pass a char * as a parameter to set the value of the current RTSP  Ses-
       sion  ID  for  the  handle. Useful for resuming an in-progress session.
       Once this value is set to  any  non-NULL  value,  libcurl  will  return
       CURLE_RTSP_SESSION_ERROR if ID received from the server does not match.
       If unset (or set to NULL), libcurl will automatically set  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.
