While [link beast.ref.boost__beast__basic_stream `basic_stream`] and [link beast.ref.boost__beast__basic_stream `tcp_stream`] support timeouts on general logical operations, the websocket stream has a more sophisticated timeout mechanism built-in which may be enabled and configured. The timeout features of the TCP or basic stream should not be used when working with a websocket stream. The interface to these timeout features is shown in this table.
While尽管 [link beast.ref.boost__beast__basic_stream `basic_stream`] and和 [link beast.ref.boost__beast__basic_stream `tcp_stream`] support timeouts on general logical operations, the webs支持对常规逻辑操作设置超时，但 WebSocket stream has a more sophisticated timeout mechanism built-in which may be enabled and configured. The timeout features of the TCP or basic stream should not be used when working with a websocket stream. The interface to these timeout features is shown in this table.流内置了更复杂的超时机制，可以启用并进行配置。在使用 WebSocket 流时，不应使用 TCP 或基础流的超时功能。这些超时功能的接口如下表所示。

To ensure timely delivery of control frames, large outgoing messages can be broken up into smaller sized frames. The automatic fragment option turns on this feature, and the write buffer size option determines the maximum size of the fragments:

When a close frame is received by during a read operation, the implementation will automatically respond with a close frame and then shut down the underlying connection before returning. In this case, the read operation will complete with the code [link beast.ref.boost__beast__websocket__error `error::closed`]. This indicates to the caller that the connection has been closed cleanly.

The close function will send a close frame, read and discard incoming message data until receiving a close frame, and then shut down the underlying connection before returning.

The WebSocket protocol defines a procedure and control message for initiating a close of the session. In this procedure, a host requests the close by sending a [@https://tools.ietf.org/html/rfc6455#section-5.5.1 ['close frame]]. To request a close use a close function such as [link beast.ref.boost__beast__websocket__stream.close.overload2 `close`] or [link beast.ref.boost__beast__websocket__stream.async_close `async_close`]:

Unlike regular completion handlers used in calls to asynchronous initiation functions, the control callback only needs to be set once. The callback is not reset after being called. The same callback is used for both synchronous and asynchronous reads. The callback is passive; in order to be called, a stream read operation must be active.

The callback is passive; in order to be called, a stream read operation must be active.与异步发起函数调用中使用的普通完成处理器不同，控制回调只需设置一次，调用后不会被重置。该回调同时用于同步和异步读取。回调是“被动”的——必须有一个流读取操作处于活动状态，回调才会被触发。
