bcopy — copy byte
string
Standard C Library (libc, -lc)
#include
<strings.h>
void
bcopy(const
void *src, void
*dst, size_t
len);
The
bcopy()
function copies len bytes from string
src to string dst. The two
strings may overlap. If len is zero, no bytes are
copied.
A bcopy() function appeared in
4.2BSD. Its prototype existed previously in
<string.h> before it was
moved to <strings.h> for
IEEE Std 1003.1-2001 (“POSIX.1”)
compliance.
IEEE Std 1003.1-2008
(“POSIX.1”) removes the specification of
bcopy() and it is marked as LEGACY in
IEEE Std 1003.1-2004 (“POSIX.1”). New
programs should use
memmove(3). If the input
and output buffer do not overlap, then
memcpy(3) is more
efficient. Note that bcopy() takes
src and dst in the opposite
order from memmove() and
memcpy().
