I read the Ram book and tried to modify a sample...

I want to fork off some small number of programs and display the ouput in my main window. I tried using fork and `file.exe` together but it just hung. The example below works if you don't call an external program and just pass a "string".

I am running Win32 and using the "new" fork()...

use IO::Handle;    
pipe(READER, WRITER);               
WRITER->autoflush(1);

if ($pid = fork) {
    close WRITER;
    my $buf = "";
    while (<READER>)
        { $buf .= $_; }
    chomp($buf);
    print "Parent Pid $$ just read this:\n$buf\n";
    close READER;
    waitpid($pid, 0);
} else {
    die "cannot fork: $!" unless defined $pid;
    close READER;
    
#    my $out = `ping 555-1212`;
    print WRITER "Child Pid $$ is sending this\n";
    print PARENT_WRT $out;
    close WRITER;
    exit;
}

Is it because of Win32 or is there a more standard way of doing this?

thanks !!!
