## Declaration

Source position: heaph.inc line 18

`type TFPCHeapStatus = record`
`MaxHeapSize: PtrUInt;` |  | Maximum allowed size for the heap, in bytes
`MaxHeapUsed: PtrUInt;` |  | Maximum used size for the heap, in bytes
`CurrHeapSize: PtrUInt;` |  | Current heap size, in bytes
`CurrHeapUsed: PtrUInt;` |  | Currently used heap size, in bytes

## Description

TFPCHeapStatus describes the state of the FPC heap manager. This is not equivalent to the THeapStatus record defined by Delphi, which contains information not meaningful for the FPC heap manager. The heap status can be retrieved by the GetFPCHeapStatus call.
