Unsetting HANDLE_FLAG_INHERIT works!
open my $oldin, '<&', \*STDIN or die $!; pipe my($r), my ($w) or die $!; open STDIN, '<&', $r or die $!; my $wh = FdGetOsFHandle(fileno $w); SetHandleInformation($wh, HANDLE_FLAG_INHERIT, 0); my $pid = system 1, 'perl -ne print'; print "pid: $pid\n"; close STDIN or die $!; open STDIN, '<&', $oldin; close $r or die $!; print {$w} "hello world! ($_)\n" for 0..9; close $w or die $!; print "waiting for slave process\n"; waitpid $pid, 0 or die $!

Title:
Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":



  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • 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).
  • Want more info? How to link or How to display code and escape characters are good places to start.
