Description

TMemoryManagerState holds statistics about memory allocations.

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. AllocMem and GetMemory can be used to allocate memory blocks. The record holds the following information :

Field	Meaning
SmallBlockTypeStates	An array of small memory block information records.
AllocatedMediumBlockCount	The number of medium sized memory blocks (blocks less than 264,749 bytes in size).
TotalAllocatedMediumBlockSize	The total number of bytes oiccupied by the medium memory blocks.
ReservedMediumBlockAddressSpace	The amount of memory reserved for medium memory blocks.
AllocatedLargeBlockCount	The number of large sized memory blocks (blocks greater than 264,748 bytes in size).
TotalAllocatedLargeBlockSize	The total number of bytes oiccupied by the large memory blocks.
ReservedLargeBlockAddressSpace	The amount of memory reserved for large memory blocks.
