## Declaration

Source position: systemh.inc line 341

`type SizeInt = LongInt;`

## Description

SizeInt is used to describe sizes of structures in FPC using a signed integer. The actual type of this type depends on the architecture: its size reflects the maximum addressable memory on the current architecture, thus it is 64-bit on 64-bit platforms, 32-bit on 32-bit platforms, and 16 bit on 16 bit platforms.
