<p>Gets a pointer to memory that contains the array buffer data.</p>
<p>Obtains a pointer to the memory region that holds the contents of the
%ArrayBuffer; modifications done to the data will be visible to JavaScript
code. If <code>size</code> is not <code>NULL</code>, the size in bytes of the memory region
will also be stored in the pointed location.</p>
<p>Note that the pointer returned by this function is not guaranteed to remain
the same after calls to other <span class="caps">JSC</span> <span class="caps">API</span> functions. If you plan to access the
data of the %ArrayBuffer later, you can keep a reference to the <code>value</code> and
obtain the data pointer at a later point. Keep in mind that if JavaScript
code has a chance to run, for example due to main loop events that result
in <span class="caps">JSC</span> being called, the contents of the memory region might be modified in
the meantime. Consider taking a copy of the data and using the copy instead
in asynchronous code.</p>
