Hi,

I've used IO::Select package and can_read to do polling in my socket. Here is my question,

while(1)  {
  my ( @read_sockets ) = $SELECT->can_read(5);
  if ( @read_sockets )  {
    foreach my $fh ( @read_sockets ) {
      my $data = <$fh>;
      print "Got data from server, $data";
      $data =~ s/\n$//;
    }
  }
}

When server sends me multiple line messages. can_read returns the socket handle and I read the first line of it(as per the above code). I thought if I do can_read again, I'll get the socket handle returned as some data is not yet read. But, can_read is blocking and not returning the socket handle.

So, what is the better way to use can_read for multi line messages??
