MEMCPY(3)

NAME
memcpy - copy byte string

LIBRARY
libc

SYNOPSIS
#include <string.h>
void *
memcpy(void * restrict dst, const void * restrict src, size_t len);
void *
mempcpy(void *dst, const void *src, size_t len);

DESCRIPTION
The memcpy() and mempcpy() functions copy len bytes from string src to string dst.

RETURN VALUES
The memcpy() function returns the original value of dst. The mempcpy() function returns a pointer to the byte directly following the last byte written in dst.

SEE ALSO
bcopy(3), memccpy(3), memmove(3), strcpy(3), wmemcpy(3)

STANDARDS
The memcpy() function conforms to isoC.

BUGS
In this implementation memcpy() is implemented using bcopy(3), and therefore the strings may overlap. On other systems, copying overlapping strings may produce surprises. Programs intended to be portable should use memmove(3) when src and dst may overlap.
