IPersistStreamInit::GetSizeMax method (ocidl.h)
Retrieves the size of the stream needed to save the object.
Syntax
HRESULT GetSizeMax(
[out] ULARGE_INTEGER *pCbSize
);
Parameters
[out] pCbSize
The size in bytes of the stream needed to save this object, in bytes.
Return value
This method returns S_OK to indicate that the size was retrieved successfully.
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 IPersistStreamInit::Save method.
Notes to Implementers
The GetSizeMax implementation should return a conservative estimate of the necessary size because the caller might call the IPersistStreamInit::Save method with a non-growable stream.Requirements
