bcopy, bcmp, bzero, ffs \- bit and byte string operations
.B bcopy(src, dst, length)
operate on variable length strings of bytes.
They do not check for null bytes as the routines in
returning zero if they are identical,
non-zero otherwise. Both strings are
zero bytes always returns zero.
\fIFfs\fP finds the first bit set in the argument passed it and returns
the index of that bit. Bits are numbered starting at 1, from the right.
A return value of 0 indicates the value passed is zero.
