/***
*wchar_t *wcsncpy(dest, source, count) - copy at most n wide characters
*
*Purpose:
*   Copies count characters from the source string to the
*   destination.  If count is less than the length of source,
*   NO NULL CHARACTER is put onto the end of the copied string.
*   If count is greater than the length of sources, dest is padded
*   with null characters to length count (wide-characters).
*
*
*Entry:
*   wchar_t *dest - pointer to destination
*   wchar_t *source - source string for copy
*   size_t count - max number of characters to copy
*
*Exit:
*   returns dest
*
*Exceptions:
*
