Hi,

I am converting a small project from Delphi to Free Pascal. I am working on a Linux (Debian) box. In several places, the software seems to call to external applications an uses this kind of command:

var
  smfMemHnd : HWND;
...
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?

thanks in advance for your help,
Gilles Marcou

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).
