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.
