[fpc-pascal] help: converting windows API to linux

[Bee]

Hi all,

I've been trying to convert a Delphi unit to FPC. The problem is the 
unit utilizes lots of low level windows APIs, such as: VirtualProtect, 
CreateEvent, CloseHandle, etc. Due my lack of linux low level API 
knowledge, I hope someone here could show me where to find a complete 
guide about similar linux API of the windows counterpart, including the 
description, the parameter lists, the API behavior differences, and 
which FPC unit should be used (instead of just windows unit).

Or maybe I should just rewrite the whole unit from scratch on linux? :-D

TIA.
