# NAME
|
|
|
|
CURLOPT_RTSP_SESSION_ID - RTSP session ID
|
|
|
|
# SYNOPSIS
|
|
|
|
~~~c
|
|
#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 the 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.
|
|
|
|
**WARNING:** when changing the URL's origin in a reused easy handle, you might
|
|
want to set or clear the Session ID to avoid reuse across different hosts.

# DEFAULT

CURLcode result;
|
|
char *prev_id = "old"; /* previously retrieved RTSP session ID */
|
|
curl_easy_setopt(curl, CURLOPT_URL, "rtsp://example.com/");
|
|
curl_easy_setopt(curl, CURLOPT_RTSP_SESSION_ID, prev_id);
