NAME
memcpy —
copy bytes
SYNOPSIS
#include
<string.h>
void *
memcpy(void
*dst, const void
*src, size_t
len);
DESCRIPTION
The
memcpy()
function copies len bytes from buffer
src to buffer dst.
RETURN VALUES
The memcpy() function returns the original
value of dst.
SEE ALSO
bcopy(3), memccpy(3), memmove(3), strcpy(3), strlcpy(3), wmemcpy(3)
STANDARDS
The memcpy() function conforms to
ANSI X3.159-1989
(“ANSI C89”).
HISTORY
The memcpy() function first appeared in
AT&T System V UNIX and was reimplemented
for 4.3BSD-Tahoe.
CAVEATS
In this implementation memcpy() is
implemented using
bcopy(3), and therefore the buffers may overlap. On other systems,
copying overlapping buffers may produce surprises. A portable, safe solution
is to use memmove(3).
