<div>
By my expireance, CopyMemory and memcpy are same,<br />
Only 1 difference: CopyMemory -&gt; it is pure Windows<br />
stuff, memcpy -&gt; portable for every c++ compilers.<br />
In fact, CopyMemory realized with help of memcpy!<br />
About RtlCopyMemory: it is simple macro for memcpy<br />
#define RtlCopyMemory(dst, src, len) memcpy(dst, src, len) <br />
See more details in <br />
