Re^3: New to perl: IO Select question :(

[Roger]

Try this instead, in case the select method returns a reference to an array:

my $rhSet = IO::Select->select($readSet, undef, undef, 0);
foreach $rh(@$rhSet)
{

You should also read the perldoc for IO::Select, there is a short example at the end.

perldoc IO::Select

EXAMPLE
     Here is a short example which shows how "IO::Select" could
     be used to write a server which communicates with several
     sockets while also listening for more connections on a
     listen socket

         use IO::Select;
         use IO::Socket;

         $lsn = new IO::Socket::INET(Listen => 1, LocalPort => 8080);
         $sel = new IO::Select( $lsn );
         while(@ready = $sel->can_read) {
             foreach $fh (@ready) {
                 if($fh == $lsn) {
                     # Create a new socket
                     $new = $lsn->accept;
                     $sel->add($new);
                 }
                 else {
                     # Process socket

                     # Maybe we have finished with the socket
                     $sel->remove($fh);
                     $fh->close;
                 }
             }
         }

Yup I'v seen that example, and tried it with can_read aswell, same thing happens :(

[Roger]

my $sock = IO::Socket::INET->new(
                                Proto=>"tcp",
                                LocalHost=>"Localhost",
                                Listen=>16,
                                Reuse=>1,
                                LocalPort=>$ARGV[0]
                                ) or die("Could not create socket!\n")
+;


my $readSet = new IO::Select();
$readSet->add($sock);

my $rhSet = IO::Select->select($readSet);

while(my @ready = $rhSet->can_read(0))
{
        foreach $rh(@ready)
        {
                if($rh == $sock)
                {
                        $newSocket=$rh->accept();
                        $readSet->add($newSocket);
                } else
                {
                        $buf=<$rh>;
                        if($buf)
                        {
                                printf "$buf";
                        } else
                        {
                                $readSet->remove($rh);
                                close($rh);
                        }
                }
        }
