The <code class="computeroutput">async_read_until</code>
function is a composed asynchronous operation that reads data into a dynamic
buffer sequence, or into a streambuf, until it contains a delimiter, matches
a regular expression, or a function object indicates a match.
</p>
<p>
Start an asynchronous operation to read data into a dynamic buffer sequence
until it contains a specified delimiter.
