#include <wchar.h>
wchar_t *wmemmove (wchar_t * dest , const wchar_t * src , size_t n );
DESCRIPTION
The wmemmove function is the wide-character equivalent of the
memmove function. It copies n wide characters from the array
starting at src to the array starting at dest. The arrays may
overlap.
The programmer must ensure that there is room for at least n wide
characters at dest.
