-
struct websockets *ws_init(struct ws_callbacks *cbs, CURLM *mhandle, struct ws_attr *attr)¶
Create a new (CURL-based) WebSockets handle.
- Parameters
cbs – set of functions to call back when server report events.
mhandle – user-owned curl_multi handle for performing non-blocking transfers
attr – optional attributes to override defaults
- Returns
newly created WebSockets handle, free with ws_cleanup()
Example¶
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);
