Description

TSmallBlockTypeState holds statistics about a small memory block.

GetMemoryManagerState returns a structure containing memory usage statistics for each block type-- small, medium, and large blocks. It returns this data in a TMemoryManagerState record. Within that record is held a TSmallBlockTypeStates field - an array of TSmallBlockTypeState records. Each TSmallBlockTypeState record holds the following information:

Field	Meaning
InternalBlockSize	Actual memory allocated to each small memory block--at least 4 bytes of which are not available in the UseableBlockSize.
UseableBlockSize	The usable size of each allocated small memory block.
AllocatedBlockCount	The number of small memory blocks of the given InternalBlockSize that are allocated.
ReservedAddressSpace	The amount of memory reserved for this group of small memory blocks.
