I'm trying to provide fd for Linux::INotify, but I'm having problems fetching that..., I tried something like that:

 my ($fd);
 open($fd,"/tmp");
 use Data::Dumper;
 print "PID: $$";
 print Dumper(\$fd);
[download]

but all I get is:

 PID: 22117
 $VAR1 = \\*{'::$fd'};

Additionally I tried looking at that pid:

wraith eyck 11:17 ~> ls /proc/22117/fd -l
total 0
lrwx------  1 eyck root 64 Sep 13 11:17 0 -> /dev/pts/44
lrwx------  1 eyck root 64 Sep 13 11:17 1 -> /dev/pts/44
lrwx------  1 eyck root 64 Sep 13 11:17 2 -> /dev/pts/44
lr-x------  1 eyck root 64 Sep 13 11:17 3 -> /tmp

Is there a way to see that from inside?
