I was using IPC::Open2 as a replacement for a pipe'd open and got caught under windows because it seems to open in binmode.

Two questions:

1. Did I miss something in the docs about IPC::Open2 opening in binmode?
2. Can someone help explain what in IPC::Open3 is resulting in binmode.

test.pl

#!perl -w
print <<EOF;
Line one
line two
line three
EOF

test script

use IO::Handle;
use IPC::Open2;

open FH, "perl test.pl|" or die $!;
while (<FH>) {
   chomp;
   print "test1:[$_]\n";
}

close FH;

my ( $rdrfh, $wtrfh );
my $pid = IPC::Open2::open2($rdrfh, $wtrfh, 'perl','test.pl' );


while (<$rdrfh>) {
   chomp;
   print "test2:[$_]\n";
}

open FH, "perl test.pl|" or die $!;
my $fd = IO::Handle->new_from_fd( fileno(FH), "r" );
while ( <$fd> ) {
   chomp;
   print "test3:[$_]\n";
}

Results in:

C:\WINDOWS\Desktop>perl t.pl
test1:[Line one]
test1:[line two]
test1:[line three]
]est2:[Line one
]est2:[line two
]est2:[line three
test3:[Line one]
test3:[line two]
test3:[line three]

I know I can solve this with:

    binmode $rdrfh, ':crlf';

But is reading in binary mode expected behavior?

Another question is why I cannot specify "rb" as the MODE above.

Thanks,
