+// Parameters:
+//			document	-	Handle to a document
+//			index		-	The index of named destination.
+//			buffer		-	The buffer to obtain destination name, used as wchar_t*.

+// Comments:
+//			Call this function twice to get the name of the named destination:
+//			1) First time pass in |buffer| as NULL and get buflen.
+//			2) Second time pass in allocated |buffer| and buflen to retrieve |buffer|, which should be used as wchar_t*.
+//			   If buflen is not sufficiently large, it will be returned as -1.
