COM Signature

From textmgr.idl:

   [out] IOleUndoManager **ppUndoManager  
);

This method could be expensive, depending upon the underlying implementation of the buffer. That is, it could be very difficult to calculate the size of the buffer if it is a virtual-line-oriented implementation of the buffer, as in Visual Basic.
