Dear Monks,

With your help, I have written a program that reads from a serial port, does some stuff with the input and writes to mysql database in a endless loop. In short it looks something like this:

while ($line = <DEV>) {
  my @values = Parse_Line($pass_some_stuff, $line);
  $sth->execute(@values) || die "Could not transfer data, $!";
}

I am looking for a way of trapping the signal when someone/something trays to "kill -N myProgram.pid" so I wouldn't loose any data ($line), and close up database connections and sio device properly.

10x ahead.

In reply to shutdown gracefully - kill signal trap by SiLiK
