ws_timestamp_update - update WebSockets current timestamp

uint64_t ws_timestamp_update(struct websockets *ws)

Update the WebSockets event-loop concept of “now”.

Parameters:

• ws – the WebSockets handle created with ws_init()

Returns:

the timestamp in milliseconds

Example

void on_connect(void *data,
                struct websockets *ws,
                struct ws_info *info,
                const char *ws_protocols)
{
  /* simulate intensive operation with sleep */
  sleep(1);

  /* update internal timestamp to account for delay */
  ws_timestamp_update(ws);
}

int main(void)
{
  struct ws_callbacks cbs = { .on_connect = &on_connect };
  CURLM *mhandle = curl_multi_init();
  struct websockets *ws = ws_init(&cbs, mhandle, NULL);
  ws_set_url(ws, "wss://example.com", NULL);

  /* run the event-loop */
  ws_start(ws);

  uint64_t tstamp;
  bool is_running;
  do {
    is_running = ws_easy_run(ws, 5, &tstamp);
  } while (is_running);

  ws_end(ws);

  ws_cleanup(ws);
  curl_multi_cleanup(mhandle);
}
