in reply to Signal Handling

You can set set the handler to a subroutine.

$SIG{INT} = sub { <code goes here> };

See perldoc perlipc.

    Is there any other work out. Actually I want to write a Interrupt Subroutine which should take Parameters. This way it's not going to work.

      Well, often what you want to do is something like:

      $SIG{INT} = sub { our $sigint_gotten = 1;};

# Later in the code

if(our $sigint_gotten){
    our $sigint_gotten = 0;
    deal_with_it($arg1, $arg2, ...);
}

      I can't imagine how you would send a SIGINT with a parameter but you can do whatever you want in the subroutine you assign to SIGINT. Just remember that you want to return control to the system ASAP once you're in the handler. Maybe something like this would work for you... 

      $SIG{INT} = sub {
    my $obj = Whatever->new();
    process_interrupt($obj)
};
