PROLOG
       This  manual  page is part of the POSIX Programmer's Manual.  The Linux
       implementation of this interface may differ (consult the  corresponding
       Linux  manual page for details of Linux behavior), or the interface may
       not be implemented on Linux.
NAME
       memmove - copy bytes in memory with overlapping areas
SYNOPSIS
       #include <string.h>
       void *memmove(void *s1, const void *s2, size_t n);

DESCRIPTION
       The memmove() function shall copy n bytes from the object pointed to by
       s2  into  the  object pointed to by s1. Copying takes place as if the n
       bytes from the object pointed to by s2 are first copied into  a  tempo-
       rary  array  of n bytes that does not overlap the objects pointed to by
       s1 and s2, and then the n bytes from the  temporary  array  are  copied
       into the object pointed to by s1.
RETURN VALUE
       The  memmove() function shall return s1; no return value is reserved to
       indicate an error.
ERRORS
       No errors are defined.
