Module Name:
mem.hxx
Abstract:
The class MEM contains one pure virtual function named 'Acquire'. The implementors and users of this class must follow some simple constraints.
Acquire will return a pointer to Size bytes of memory or NULL.
A function taking a MEM as an argument should call Acquire at most one time. It should not, for instance, cache a pointer to the MEM for future calls to Acquire.
