"memcpy". The differences are:
1) the first and second arguments are reversed:
bcopy(from, to, count);
becomes
memcpy(to, from, count);
2) "memcpy" makes no guarantees that it'll work right if "from"
and "to" overlap; I don't have the 4.3-tahoe manual page
handy to see whether it guarantees that it'll work, but I
think most implementations do guarantee that, and some code
relies on it working. (The SunOS "bcopy" manual page says
that "Overlapping strings are handled correctly.")
