The first page you linked to contains pretty much all you need to locate that information.

Example:

HANDLE memory_handle = 
    OpenFileMapping(MAP_FILE_ALL_ACCESS, FALSE, "Creatures 3_mem");

Googling for "OpenFileMapping MSDN" brings up http://msdn.microsoft.com/library/en-us/fileio/base/openfilemapping.asp as the first link. Pasting the prototype given at the top of the page into Win32::API::Prototype along with "Kernel32.dll" located near the bottom, and supply the constants and you should be able to get access to the shared memory segement (assuming you have whatever application creates it running on your machine).

A similar process for each of the other APIs listed at your link would get you a long way towards your goal.

Ok, I tried that. BUT... (oh no...)

I get this error: Modification of a read-only value attempted at C:/Perl/site/lib/Win32/API/Type.pm line 195, <DATA> line 164.

Here's my code:

use Win32::API;

my $STANDARD_RIGHTS_REQUIRED = (0x000F0000);
my $SECTION_QUERY             = 0x0001;
my $SECTION_MAP_WRITE         = 0x0002;
my $SECTION_MAP_READ         = 0x0004;
my $SECTION_MAP_EXECUTE         = 0x0008;
my $SECTION_EXTEND_SIZE         = 0x0010;
my $SECTION_ALL_ACCESS         = ($STANDARD_RIGHTS_REQUIRED|$SECTION_Q
+UERY|
                                $SECTION_MAP_WRITE       |$SECTION_MAP
+_READ|
                                $SECTION_MAP_EXECUTE     |$SECTION_EXT
+END_SIZE);

Win32::API->Import('kernel32', 'HANDLE OpenFileMapping(DWORD dwDesired
+Access, BOOL bInheritHandle, LPCTSTR lpName)');

my $foo = OpenFileMapping($SECTION_ALL_ACCESS, 0, "Creatures 3_mem");
