NAME
       memmove - copy memory area

SYNOPSIS
       #include <string.h>

       void *memmove(void *dest, const void *src, size_t n);

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

RETURN VALUE
       The memmove() function returns a pointer to dest.
