in thread New to perl: IO Select question :(

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; } } }
