address: size segment-type owner [handle flags chain]

address

Specifies physical and heap addresses.

size

Specifies the size of the object, in bytes.

segment-type

Specifies the type of object. The type can be any one of the following:

CODE	Segment contains application code.

FREE	Segment belongs to pool of free memory objects ready for allocation by an application.
PRIV	Segment contains private data.
SENTINAL	Segment marks the beginning or end of the global heap.

owner

chain

Specifies the previous and next addresses in the LRU list.
