nopoll_conn_is_ok
| Definition: |
include nopoll.e
bool ok = nopoll_conn_is_ok(atom conn) |
| Description: |
Check if the provided connection is in connected state (just to the connection).
conn: The websocket connection to be checked. This is different to be ready to send and receive content because the session needs to be first established. You can use nopoll_conn_is_ready() to ensure the connection is ready to be used (read or write operation can be done because handshake has finished). For example, you might connect to a raw socket server and nopoll_conn_is_ok will report that everything is ok because the socket is indeed connected but because you are connecting to a non-websocket server, it will not work because the WebSocket session establishment didn’t take place and hence nopoll_conn_is_ready() will fail. Returns: true in the case the connection is working otherwise false is returned. |
| Example: |
include nopoll.e
atom ctx = nopoll_ctx_new()
atom conn = nopoll_conn_new(ctx, "echo.websocket.org", "80", NULL, "/", NULL, NULL)
if not nopoll_conn_is_ok(conn) then
-- some error handling here
end if
if not nopoll_conn_wait_until_connection_ready(conn, 5) then
-- some error handling
end if
if nopoll_conn_send_text(conn, "Hello there! this is a test", 27) != 27 then
-- yet more error handling
end if
