/***

*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
