Snapshot Properties
`Address:PtrUInt;`	Address of the Heap Block
`Size:PtrUInt;`	Size of the Heap Block (including the size of the THeapBlock structure)
`State:LongWord;`	State of the Heap Block (eg HEAP_STATE_FREE)
`Flags:LongWord;`	Flags of the Heap Block (eg HEAP_FLAG_SHARED)
`Affinity:LongWord;`	CPU Affinity of the Heap Block (eg CPU_AFFINITY_0)
Internal Properties
`Next:PHeapSnapshot;`	Next entry in Heap snapshot

Address	The starting address for the reservation. The memory manager may reserve a block that starts prior to the supplied address for alignment purposes.
Size	The total size in byte to be reserved, the memory manager may increase the amount reserved to cater for alignment or to prevent orphan blocks. Size must be greater than 0.
Return	A pointer to the actual reserved memory which may differ from the supplied starting address due to alignment. The reservation can be cancelled by passing the returned pointer to FreeMem.

Hint	The hint provides the requested base address of the heap block but may be overridden by the memory manager if the block is already partially or fully allocated, pass nil if any heap block is suitable
Size	The size provides the requested size of the heap block. Size must be a power of 2 and both Hint and the returned pointer must be aligned on a multiple of HEAP_REQUEST_ALIGNMENT. Flags provides the heap block flags such as shared, local, code, device, nocache etc.
Affinity	The affinity provides the processor affinity mask, a mask of 0 indicates no specific processor
Return	The return is the heap block that has been registered or nil if the request failed
Note	To allocate this memory use GetMemEx/AllocMemEx etc. The return value points directly to the heap block, to access the memory referenced by the heap block you must add SizeOf(THeapBlock) to this value.

Hint	The hint provides a requested base address of the local heap block but may be overridden by the memory manager if the block is already partially or fully allocated, pass nil if any heap block is suitable
Size	The size provides the requested size of the heap block. Size must be a power of 2 and both Hint and the returned pointer must be aligned on a multiple of HEAP_REQUEST_ALIGNMENT.
Affinity	The affinity provides the processor affinity mask, a mask of 0 indicates no specific processor
Return	The return is the heap block that has been marked as local or nil if the request failed (The memory management unit should mark this region of memory as local or non global)
Note	To allocate local memory use GetLocalMem/AllocLocalMem etc. The return value points directly to the heap block, to access the memory referenced by the heap block you must add SizeOf(THeapBlock) to this value.

Note	Alignment must be a power of 2
Note	The memory must be freed using FreeIRQMem

Return	Return The return is the split portion of the block
Note	Caller must remove block from the free list. Caller must add split block to the free list. Caller must hold the heap lock

Return	The return is the merged result of the blocks
Note	Caller must remove block from the free list. Caller must add merged block to the free list. Caller must hold the heap lock

Size	The size has already been normalized to alignment and includes the size of the Heap Block
Note	Caller must hold the heap lock

Size	The size is the exact size and has not been normalized
Note	Caller must hold the heap lock

Address	The address has already been normalized to include the Heap Block
Note	Caller must hold the heap lock

Return	The return is the split portion of the block
Note	Caller must remove block from the IRQ free list. Caller must add split block to the IRQ free list. Caller must hold the IRQ heap lock
