<p>These generic functions are used to implement subclasses of
fundamental-output-stream:

<div class="defun">

<blockquote><p><a name="index-sb_002dgray_003astream_002dclear_002doutput-356"></a>This is like <code>cl:clear-output</code>, but for Gray streams: clear the given
output <code>stream</code>. The default method does nothing.

<blockquote><p><a name="index-sb_002dgray_003astream_002dfinish_002doutput-358"></a>Attempts to ensure that all output sent to the Stream has reached
its destination, and only then returns false. Implements
<code>finish-output</code>. The default method does nothing.

<blockquote><p><a name="index-sb_002dgray_003astream_002dforce_002doutput-360"></a>Attempts to force any buffered output to be sent. Implements
<code>force-output</code>. The default method does nothing.
