You could try Win32::SocketPair::winopen2.

I haven't been able to get it to work here, but I'm still at 5.8.6 (and have no intention of going to 5.8.8). Maybe it'll work for you.

I was surprised to see Corion suggest named pipes since I don't believe that 4-arg select works on named pipes in Win32.

Yes, I'd try something like Win32::Socketpair (your capital "P" makes your link go astray). If the module doesn't work, there really isn't all that much code there so I'd be a bit surprised if the module itself has problems on Perl 5.8.6 but I'd be really surprised if it was difficult to fix the module or even roll your own replacement (all you need to do is create quite ordinary TCP sockets). If one runs into problems, one can also look at the code for Win32::Sel­ectablePip­e that still sits on my scratchpad that I was trying to get turned into a module very similar to Win32::Socketpair (except that it would know how to override pipe so that it could fix already-written code to make it work on Win32).

Win32::Socketpair did the trick. Apparently pipes aren't handled well when redirecting STDIO.

The module does exactly the same thing to redirect the STDIN/STDOUT that I tried without success. The big difference was that it was using a network socket instead of a pipe.

For the record, I did have to set the handles to autoflush in both the client and server code in order for things to work properly.

Thanks for your help.

# In the server:
    use IO::Handle;
    my @command = ( 'perl', 'client.pl' );
    my ($started, $fd)= winopen2( @command );
    $fd->autoflush;

# and the client:
    use IO::Handle;
    STDIN->autoflush;
    STDOUT->autoflush;

    print "$_" while <>;
