Re: How to approach this i by Perl?

I tend to use a socketpair for things like this...

I am not quite sure how I can use socketpair to resolve my issue.

I think I will try to get the threaded program working. I will need some help. Here is relevant sections of the code

use vars qw(%conn $ssh);
share(%conn);
share($ssh);

#code run by thread
#Here is where I get the error
#Invalid value for shared scalar at
$ssh =  function();

# in the function
sub function {
# Create a new pseudo terminal
$pty = new IO::Pty
$ssh = new Net::Telnet (-fhopen => $pty)
return $ssh
}
# in the Telnet module the code looks like this
sub new {
   my ($class) = @_;
   $self = $class->SUPER::new;
   *$self->{net_telnet} = {
          bin_mode       => 0,
          blksize        => &_optimal_blksize(),
    .
    .
    .
   }
   $self
}

Any idea how I can go about sharing $ssh object created by thread? Is it worth pursuing to use thread to solve this?

Thanks Ashok

You said you create forks, I assume you have a central script that these forks are created from. Create a socket pair for each fork and pass data back and forth over them. You can use something like IO::Select to see what has data waiting. Another option would be to maintain a file or directory with proper locking, or use regular sockets. There are many ways to go about it. Even signals could probably work for minor notification stuff.
