NAME
bcopy —
LIBRARY
Standard C Library (libc, -lc)SYNOPSIS
#include <strings.h>
void
bcopy(const
void *src, void
*dst, size_t
len);
DESCRIPTION
Thebcopy() function copies len
bytes from string src to string
dst. The two strings may overlap. If
len is zero, no bytes are copied.
SEE ALSO
memccpy(3), memcpy(3), memmove(3), strcpy(3), strncpy(3)HISTORY
Abcopy() 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().
