I'm trying to read DATA in a parent and in a child process, but seem to be unable to achieve this.
Simply using <DATA> didn't work.
So I tried fdopen, but still just the parent seems to be able to read my DATA.
What am I doing wrong?
use IO::Handle;
use strict;
use warnings;
my $x= IO::Handle->new();
$x->fdopen(fileno(DATA), "r");
my $y= IO::Handle->new();
$y->fdopen(fileno(DATA), "r");
my $pid= fork();
die unless defined $pid;
if ($pid == 0) {
print "Start c\n";
while (<$x>) {
print "c: $_"; sleep 1;
}
print "stop c\n";
}
else {
print "Start p\n";
while (<$y>) {
print "p: $_"; sleep 1;
}
print "stop p\n";
}
__DATA__
a
b
c
d
e
Output is:
Start p
p: a
Start c
stop c
p: b
p: c
p: d
p: e
stop p
Update In an earlier version I mixed up parent and child. Fixed.

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).

or How to display code and escape characters
are good places to start.
