yes, you can do something like:
#!/usr/bin/perl -w
use strict;
set_it_up();
print "from set_it_up(), i got: ", scalar <STDIN>;
close(STDOUT);
sub set_it_up{
my $pid;
return if $pid = open(STDOUT,"|-");
die("Unable to attache to STDOUT by fork: $!") unless(defined $pid);
print "hello world\n";
}
__END__
inside set_it_up() you are redirecting STDOUT back to your script. see if
that's what you need.
