<h3>Usage Notes</h3>
|
|
|
|
<ul>
|
|
<li>The size value is rounded up to a multiple of the minimum boundary
|
|
specified when the heap space is created. The minimum boundary for the
|
|
activation group default heap is 16 bytes.</li>
|
|
|
|
<li>The address of the first byte of the allocation begins on a boundary at
|
|
least as great as the minimum boundary specified when the heap is created. The
|
|
minimum boundary for the activation group default heap is 16 bytes.</li>
|
|
|
|
<li>A <em>heap_id</em> of 0 specifies the default heap in the activation
|
|
group.</li>
|
|
|
|
<li>Individual allocations within a heap may not be contiguous.</li>
|
|
|
|
<li>Each allocation associated with a heap provides a sequence of contiguously
|
|
addressable bytes. The bytes do not cross a 64KB boundary unless the allocation
|
|
size is greater than 64KB.</li>
|
|
</ul>
