51<h2>Description</h2>
52    <div class="section">
53<p>Uses the CPU to perform memory copy. The function behaves normally even if the copy source region overlaps the copy destination region.</p><p>When alignment is undefined, this function is faster than  <CODE>std::memmove</CODE> because at runtime it selects the optimal method based on  the alignment of the copy source/destination addresses. But use <CODE>std::memmove</CODE> for u32* and structures, and other cases where alignment is determined statically and the copy source/destination addresses are aligned the same.</p><!-- write here --></div>
