A handler must meet the requirements of <code class="computeroutput">MoveConstructible</code> types
(C++Std [moveconstructible]).
</p>
<p>
In the table below, <code class="computeroutput">X</code> denotes a handler class, <code class="computeroutput">h</code>
denotes a value of <code class="computeroutput">X</code>, <code class="computeroutput">p</code> denotes a pointer to a
block of allocated memory of type <code class="computeroutput">void*</code>, <code class="computeroutput">s</code> denotes
the size for a block of allocated memory, and <code class="computeroutput">f</code> denotes a function
object taking no arguments.
