Description

A subclass of <stream> supporting the Stream Extension Protocol and the Buffer Access Protocol. It is not instantiable.

Streams of this class support the buffer-size: init-keyword, which can be used to suggest the size of the stream's buffer. However, the instantiated stream might not use this value: it is taken purely as a suggested value. For example, a stream that uses a specific device's hardware buffer might use a fixed buffer size regardless of the value passed with the buffer-size: init-keyword.

In general, it should not be necessary to supply a value for the buffer-size: init-keyword.
