So I *think* it's safe to call DmWrite were the source and destination
overlap, but I thought I'd ask anyway. I think it's safe because my code
seems to work and because I figure DmWrite gets a semaphore, toggles the
memory protection bit and then call MemMove. MemMove is documented as safe
which I assumemeans that it checks for the direction of the overlap and
copies top to bottom or bottom to top depending.
Does anyone know for sure? Would be nice if this was documented somewhere!
(didn't see it in 3.5 docs or O'Reily book). Would save us developers some
time.
Thanks,
LL
