CURLINFO_RTSP_SESSION_ID(3) Introduction to Library Functions

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(curl) {
CURLcode result;
curl_easy_setopt(curl, CURLOPT_URL, "rtsp://rtsp.example.com");
result = curl_easy_perform(curl);
if(result == CURLE_OK) {
char *id;
curl_easy_getinfo(curl, CURLINFO_RTSP_SESSION_ID, &id);
}
curl_easy_cleanup(curl);
}
}

AVAILABILITY
