Hi,

There are a number of perlipc features that I would like to use on Windows:

1) open(KID_TO_READ, "-|")

If I use the following code:

    # add error processing as above
    $pid = open(KID_TO_READ, "-|");    if ($pid) {   # parent
        while (<KID_TO_READ> ) {
            # do something interesting
        }
        close(KID_TO_READ) || warn "kid exited $?";    } else {      #
+ child
        ($EUID, $EGID) = ($UID, $GID); # suid only
        exec($program, @options, @args)
            || die "can't exec program: $!";
        # NOTREACHED
    }

It works on Linux but on Windows I get the following error:
'-' is not recognized as an internal or external command, operable pro
+gram 
or batch file.

2) timeout using `<system command> ` method

If I use the following code:

  eval{
    # Set the callback for the alarm signal
    local $SIG{ALRM} = sub { die ($TIMEOUTERROR) };

    # Specify the alarm timeout
    alarm($TIMEOUT);

    my @OUTPUT=`$COMMAND 2> &1`;
  };

  alarm(0);

If the command specified by $COMMAND takes longer than the timeout specified, then the script times out successfully on Linux but on Windows, the script still waits for the command to finish.

Please could someone let me know if this functionality is not expected to work on Windows and if there are other ways of doing this.

Thank you.
