IPersistStream::GetSizeMax (Windows Embedded CE 6.0)

1/6/2010

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.
