Is this correct for undo/redo operations in FDK?

I would like someone to assure me that the following way is the correct one:

In the beginning I enable FDK Undo recording with :

F_ApiSetInt(FV_SessionId, FV_SessionId, FP_UndoFDKRecording, True);

And later on at some point I do:

F_ApiUndoStartCheckPoint(docId, ConStringT("Replacements"));

// .. replacements ..

F_ApiUndoEndCheckPoint(docId);

Is this enough?
