Does a memcpy() between buffers.

But it's a memmove.

Thanks for the report, but it explains functionality, not accurate implementation detail.

That is relevant to the functionality! If I have a buffer

<Buffer 68 65 6c 6c 6f 20 00 77 6f 72 6c 64>

and want to get rid of that nullbyte, moving the stuff inside the buffer wouldn't be safe if I used a memcpy. I would need to allocate a second buffer. However, because it's a memmove, I can do that.

I see, I will fix soon.
