+/***
+*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).
