Detailed Description

template<class T>
class NullAllocator< T >

NULL allocator.

Template Parameters

T	class or type

A NullAllocator is useful for fixed-size, stack based allocations (i.e., static arrays used by FixedSizeAllocatorWithCleanup).

A NullAllocator always returns 0 for max_size(), and always returns NULL for allocation requests. Though the allocator does not allocate at runtime, it does perform a secure wipe or zeroization during cleanup.
