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);
}
