# NAME

`bcopy` —
copy byte string

# SYNOPSIS

`#include <sys/systm.h>`

void
`bcopy`(const void *src, void *dst, size_t len);

# DESCRIPTION

The `bcopy`() interface is obsolete.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.
