CURLOPT_RTSP_SESSION_ID - Man Page
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; /* 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); } }
Availability
Added in curl 7.20.0
Return Value
Returns CURLE_OK if the option is supported, CURLE_UNKNOWN_OPTION if not, or CURLE_OUT_OF_MEMORY if there was insufficient heap space.
