wmemmove - copy an array of wide-characters
wchar_t *wmemmove(wchar_t *dest, const wchar_t *src, size_t n);
The wmemmove() function is the wide-character equivalent of the memmove(3) 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.
wmemmove() returns dest.
