CURLOPT_RTSP_SESSION_ID - set RTSP session ID

#include <curl/curl.h>

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

Pass a char * 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 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.

ret = curl_easy_perform(curl);
