wmemcpy - copy an array of wide-characters
wchar_t *wmemcpy(wchar_t *dest, const wchar_t *src, size_t n);
The wmemcpy() function is the wide-character equivalent of the memcpy(3) function. It copies n wide characters from the array starting at src to the array starting at dest.
The arrays may not overlap; use wmemmove(3) to copy between overlapping arrays.
The programmer must ensure that there is room for at least n wide characters at dest.
wmemcpy() returns dest.
