Perl Check - Need Help

[Jerry Benton]

I have it working under both FIFO and UNIX, so I guess I did it right. Final code for record keeper’s sake:


  use IO::Socket::UNIX;

  sub KickMessage {
    my($queue2ids, $sendmail2) = @_;
    my($queue);

    # Do a kick for every queue that contains some message ids
    foreach $queue (keys %$queue2ids) {
      next unless $queue2ids->{$queue};

      my $pf_connection = '/var/spool/postfix/public/qmgr';
      
      if(-S $pf_connection){
      	# UNIX
	  	my $fh = IO::Socket::UNIX->new(
				 Type => SOCK_STREAM,
				 Peer => $pf_connection,
				 ) or
		MailScanner::Log::WarnLog("KickMessage coould not write to UNIX > $pf_connection");
		print $fh "I";
		close $fh;	
	  }elsif(-p $pf_connection){
	  	# FIFO
		my $fh = new FileHandle;
		open(my $fh, '>', $pf_connection) or
		MailScanner::Log::WarnLog("KickMessage coould not write to FIFO > $pf_connection");
		print $fh "I";
		close $fh;
	  }else{
	  	MailScanner::Log::WarnLog("Unable to determine socket type (FIFO/UNIX) > $pf_connection");
	  }
    }
    return 0;
  }
