IPersistStream::GetSizeMax
Returns the
size in bytes of the stream needed to save the object.
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.
Remarks
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 Implementers
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.
