NAME

       memmove - copy memory area

LIBRARY

       Standard C library (libc, -lc)

SYNOPSIS

       #include <string.h>

       void *memmove(void dest[.n], const void src[.n], 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.
