This method returns the size, in bytes, of the stream needed to save the object.
Syntax
HRESULT GetSizeMax(
ULARGE_INTEGER* pcbSize
);
Parameters
- pcbSize
[out] Pointer to a 64-bit unsigned integer value indicating the size, in bytes, of the stream needed to save this object.
Return Value
If the size was successfully returned, the method returns S_OK.
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.
To determine whether the platform supports this interface, see Determining Supported COM APIs.
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.
