The
bcopy() interface is obsolete.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.
