IPersistMemory::GetSizeMax
Returns the
size in bytes of the memory block needed to save the object.
HRESULT GetSizeMax(
|
ULARGE_INTEGER* pcbSize |
//Pointer to size of memory needed to save object |
|
); |
|
Parameter
pcbSize
[out]Pointer
to a 64-bit unsigned integer value indicating the size in bytes of the memory
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 IPersistMemory::Save
method.
Notes to Implementers
The GetSizeMax
implementation must return a conservative estimate of the necessary size
because the IPersistMemory::Save method uses a fixed size memory block.
