HRESULT GetSizeMax(
ULARGE_INTEGER *pcbSize
| //Pointer to size of stream needed to save object
| );

Parameter
pcbSize
[out]Points to a 64-bit unsigned integer value indicating the size in bytes of
the stream needed to save this object.
Return Value
S_OK
The size was successfully returned.
Comments
This method returns the size needed to save an object. You can call this
method to determine the size and set the necessary buffers before calling the IPersistStream::Save method.
Notes to Implementors
The GetSizeMax implementation should return a conservative estimate of the necessary size
because the caller might call the IPersistStream::Save method with a non-growable stream.
