Instructs the object to save its persistent data to memory.
HRESULT retVal = object.Save(pvMem, fClearDirty, cbSize);
- pvMem [in]
The address of the memory in which the object should save up to cbSize bytes of its data. The object must not write past the address (BYTE*)((BYTE *)pvMem+cbSize).
- fClearDirty [in]
A flag indicating whether the object should clear its dirty state on return from IPersistMemory::Save, or leave that state as is.
- cbSize [in]
Type: unsigned long
The amount of memory available at pvMem to which the object can write its data.
Any object that implements IPersistMemory has some information to save persistently; therefore, E_NOTIMPL is not a valid return code.
The caller should allocate as many bytes as the object returns from IPersistMemory::GetSizeMax.
