CURLINFO_RTSP_SESSION_ID(3) Library Functions Manual
NAME
CURLINFO_RTSP_SESSION_ID - RTSP session ID
SYNOPSIS
#include <curl/curl.h>
CURLcode curl_easy_getinfo(CURL *handle, CURLINFO_RTSP_SESSION_ID, char **id);
DESCRIPTION
Pass a pointer to a char pointer to receive a pointer to a string
holding the most recent RTSP Session ID.
Applications wishing to resume an RTSP session on another connection
should retrieve this info before closing the active connection.
The id pointer is NULL or points to private memory. You must not free
it. The memory gets freed automatically when you call
curl_easy_cleanup(3) on the corresponding curl handle.
PROTOCOLS
This functionality affects rtsp only
EXAMPLE
int main(void)
{
CURL *curl = curl_easy_init();

if(result == CURLE_OK) {
char *id;
curl_easy_getinfo(curl, CURLINFO_RTSP_SESSION_ID, &id);
}
curl_easy_cleanup(curl);
}
}
