A <span class="emphasis"><em>constant buffer sequence</em></span> represents a set of memory
regions that may be used as input to an operation, such as the <code class="computeroutput"><span class="identifier">send</span></code> operation of a socket.
</p>
<p>
A type <code class="computeroutput"><span class="identifier">X</span></code> meets the <code class="computeroutput"><span class="identifier">ConstBufferSequence</span></code> requirements if it
satisfies the requirements of <code class="computeroutput"><span class="identifier">Destructible</span></code>
(C++Std [destructible]) and <code class="computeroutput"><span class="identifier">CopyConstructible</span></code>
(C++Std [copyconstructible]), as well as the additional requirements listed
below.
</p>
<p>
In the table below, <code class="computeroutput"><span class="identifier">x</span></code> denotes
a (possibly const) value of type <code class="computeroutput"><span class="identifier">X</span></code>,
and <code class="computeroutput"><span class="identifier">u</span></code> denotes an identifier.
