void
bcopy(const void *src, void *dst, size_t len)
)
interface is obsolete.
Do not add new code using it.
It will soon be purged.
Use
memcpy(9)
instead.
(The
bcopy()
function is now a macro for
memcpy(9).)
The
bcopy()
function
copies
len
bytes from string
src
to string
dst.
Unlike
bcopy(3)
the two strings must not overlap!
In the traditional
BSD
kernel, overlapping copies were handled by the now-purged
ovbcopy()
function.
If you need to copy overlapping data, see
memmove(9).
If
len
is zero, no bytes are copied.
