試用方式：

* 用多個瀏覽器分頁開啟該應用。
* 從每個分頁傳送訊息。
* 然後關閉其中一個分頁。

這會引發 `WebSocketDisconnect` 例外，其他所有用戶端都會收到類似以下的訊息：

```
Client #1596980209979 left the chat
```

/// tip

上面的應用是一個極簡範例，用來示範如何處理並向多個 WebSocket 連線廣播訊息。

但請注意，因為所有狀態都在記憶體中的單一 list 裡管理，它只會在該程序執行期間生效，且僅適用於單一程序。

		p.get('.')
		tok := p.next()
		ext = tok.String()
	}
	if p.peek() == lex.LSH {
		// parses left shift amount applied after extension: <<Amount
		p.get(lex.LSH)
		tok := p.get(scanner.Int)
		amount, err := strconv.ParseInt(tok.String(), 10, 16)
		if err != nil {
			p.errorf("parsing left shift amount: %s", err)
		}
		num = int16(amount)
	} else if p.peek() == '[' {
		// parses an element: [Index]

* Write messages from them.
* Then close one of the tabs.

That will raise the `WebSocketDisconnect` exception, and all the other clients will receive a message like:

```
Client #1596980209979 left the chat
```

/// tip

The app above is a minimal and simple example to demonstrate how to handle and broadcast messages to several WebSocket connections.

* Отправьте из них сообщения.
* Затем закройте одну из вкладок.

Это вызовет исключение `WebSocketDisconnect`, и все остальные клиенты получат следующее сообщение:

```
Client #1596980209979 left the chat
```

Приложение выше - это всего лишь простой минимальный пример, демонстрирующий обработку и передачу сообщений нескольким веб-сокет соединениям.

specific to each architecture.
The sections below list these.

<p>
One detail evident in the examples from the previous sections is that data in the instructions flows from left to right:
<code>MOVQ</code> <code>$0,</code> <code>CX</code> clears <code>CX</code>.
This rule applies even on architectures where the conventional notation uses the opposite direction.

// Read - reads single record.
// Once Read is called the previous record should no longer be referenced.

Cela lèvera l'exception `WebSocketDisconnect`, et tous les autres clients recevront un message comme :
