-        A dynamic buffer encapsulates memory storage that may be automatically resized
-        as required, where the memory is divided into an input sequence followed
-        by an output sequence. These memory regions are internal to the dynamic buffer
-        sequence, but direct access to the elements is provided to permit them to
-        be efficiently used with I/O operations, such as the <code class="computeroutput">send</code> or
-        <code class="computeroutput">receive</code> operations of a socket. Data written to the output sequence
-        of a dynamic buffer sequence object is appended to the input sequence of
