This method returns the size in bytes of the stream needed to save the object.
Syntax
HRESULT GetSizeMax(
ULARGE_INTEGER* pcbSize
);
Parameters
- 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 IPersistStreamInit::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 IPersistStreamInit::Save method with a nongrowable stream.
