according to the C library, memmove handle overlapps, you mismatch with
memcpy which does not.
The above is not memmove, it's slice assignment, which is specifically
illegal for overlaps:
$ cat testsliceassign.d
void buffer[100];
void main()
{
buffer[1..$] = buffer[0..$-1];
}
$ dmd testsliceassign.d
$ ./testsliceassign
object.Error@(0): Overlapping arrays in copy: 98 byte(s) overlap of 99
ok. i was, wrongly, suposing that this operation uses memmove under the
hood.
btw you forgot to grow the array size, if i dare.
Heh, it was just to demonstrate the error :) The code does a whole lot
of nothing, actually.
