Called to decommit the memory when the last buffer is freed.
Syntax
virtual void Free(void) PURE;
Parameters
None.
Return Value
None.
Remarks
This member function must be implemented in the derived class. It is called from CBaseAllocator::ReleaseBuffer when a decommit is pending and the allocator has put its last buffer on the free list. It is also called from CBaseAllocator::Decommit.
The CMemAllocator::Free member function is an example of how this can be implemented in the derived class. In this case, it simply returns, because the CMemAllocator class releases memory from its destructor.
This member function is protected.
