CURLOPT_RTSP_SESSION_ID(3)

NAME
CURLOPT_RTSP_SESSION_ID - RTSP session ID

SYNOPSIS
#include <curl/curl.h>
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_RTSP_SESSION_ID, char *id);

DESCRIPTION
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 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.

DEFAULT
NULL

PROTOCOLS
RTSP

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 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.
