I am converting a small project from Delphi to Free Pascal. I am

on a Linux (Debian) box. In several places, the software seems to call

...
smfMemHnd := CreateFileMapping(HWND($FFFFFFFF), nil, PAGE_READWRITE,
0,
memFileSize , memFileName);
Free Pascal seems unable to find the function CreateFileMapping. While
browsing the RTL, this function seems to be part of some Windows
related
library.
I have two questions:
1/ Which unit shall I add to my .pas file for FPC to find this
function?
2/ If this is Windows specific, how do I manage this on other
architectures?
It is Windows-specific. On *nix platforms (such as Linux), you can
probably use fpmmap instead (it's in the baseunix unit). See http://www.freepascal.org/docs-html/rtl/baseunix/fpmmap.html
, or "man mmap", for more information. Note that it expects a file
descriptor rather than a file name (but there's an example program on
that page that demonstrates how to use it).
