/***
*wchar_t *wcsncat(front, back, count) - append count chars of back onto front
*
*Purpose:
* Appends at most count characters of the string back onto the
* end of front, and ALWAYS terminates with a null character.
* If count is greater than the length of back, the length of back
* is used instead. (Unlike wcsncpy, this routine does not pad out
* to count characters).
*
*Entry:
* wchar_t *front - string to append onto
* wchar_t *back - string to append
* size_t count - count of max characters to append
*
*Exit:
* returns a pointer to string appended onto (front).
*
*Uses:

*Exceptions:
