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  temporary  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.
