NAME

6       memmove - copy memory area
7

SYNOPSIS

9       #include <string.h>
10
11       void *memmove(void *dest, const void *src, size_t n);
12

DESCRIPTION

14       The  memmove()  function  copies n bytes from memory area src to memory
15       area dest.  The memory areas may overlap: copying takes place as though
16       the  bytes in src are first copied into a temporary array that does not
17       overlap src or dest, and the bytes are then copied from  the  temporary
18       array to dest.
19

RETURN VALUE

21       The memmove() function returns a pointer to dest.
