Resolved Is UnsafeUtility.MemMove guaranteed to support overlapping memory blocks?

I'm curious if the implementation of UnsafeUtility.MemMove is guaranteed on every platform to support overlapping memory blocks. (like memmove in C).

My use case is quite unique, but I basically want to resize a container. Before resizing I need to move certain scattered data (from inside the container) to the front of the container.
I'd prefer if I could do this in-place without a temporary buffer.
This in-place memory moving could have sourcePtr being between desinationPtr and
destinationPtr+moveAmount. (which is what i mean with overlapping memory blocks).

I did a few tests on my windows pc in editor & it did support it. (sourcePtr==destinationPtr, sourcePtr inside destination memory block & destinationPtr inside source memory block)
But can I assume MemMove on every platform supports overlapping memory blocks?

Ok, now I feel silly. Didn't know these unsafe methods were documented.
Thanks!
