Interesting!
I had another look, and it turns out that the Delphi code is just a separate DLL that doesn’t know anything about Perl internals. It is not called directly from Perl, but via Win32-API. Therefore Win32::MemMap does indeed seem to work on multiple Perl versions as long as you have the correct version of Win32::API installed. I don’t follow your questions about named pipes though. Win32::MemMap is about shared memory, not named pipes. What am I missing?

I felt I had nothing to loose here, so I modified the architecture line in the ppd to say ‘MSWin32-x86-multi-thread-5.8’ (knowing that ten years ago likely his module is probably not thread safe – as im a newbie and don’t yet even program with threads). I was pleasantly surprised to see that ppm did then install from my locally available files. the first tests I ran with it actually worked. my main problem here is I don’t understand his naming scheme for the win32 named pipe. running sysinternals accesschk –osv, I see a named pipe as EPICIPCDPLX. the win32 programmer who created this named pipe (in a win32 delphi program) references this named pipe as \\.\pipe\EPICIPCDPLX <file:///\\.\pipe\EPICIPCDPLX> yet in amines test scripts, he uses a rather different naming convention for his ‘sample named pipe’. here is his code fragment… use Win32::MemMap; my $size=12349; # size in bytes my $obj=new Win32::MemMap; my $mem=$obj->OpenMem("//MemMap/Perl",$size); $obj->LastError; $size = $mem->GetSize(); print "size of sm = $size\n"; $datasize = $mem->GetDataSize(); print "datasize of sm = $datasize\n"; this program does actually run and work for perl 5.8 build 822. however I don’t understand how I would\should convert my existing win32 named pipe from \\.\pipe\EPICIPCDPLX <file:///\\.\pipe\EPICIPCDPLX> to his naming syntax? //EPICIPCDPLX //MemMap/EPICIPCDPLX its not very clear to me, so I cant interact with the (already defined by another win32 process) shared memory map. any suggestions? _____ From: Jan Dubois [mailto:j...@activestate.com] Sent: Monday, October 18, 2010 4:03 PM To: gai...@visioninfosoft.com; david.wag...@fedex.com; perl-win32-users@listserv.activestate.com Subject: RE: looking for amine's 'MemMap' module for Win32 x86 Perl version 5.8 If you follow that line of reasoning, then you have to realize that Perl 5.8 wasn’t out in 2001 either, so the binary really would be for 5.005 or 5.6. The ppd file and tarball don’t seem to match up.

[Wags] Unsure what happened or where Amine went, but to the best of my knowledge he vanished from the Perl scene almost 10 years ago, give or take a year or two. I had another module of his which I was using and it had to do with changes within a folder for a file. Much nicer than anything else that was around, but it quit working and Amine quit responding. So unsure who is maintaining and handling. Now, I could be completely wrong, but I have not seen or heard of Amine on any of the Perl lists. Anyone know differently?? Unsure who would be maintaining the code, but not changing who is actually handling the changes??? If you have any questions and/or problems, please let me know. Thanks. Wags ;) David R.
