Monks,

I've many questions raising now., Let me tell what's in my mind.

So, is it a very worse idea to use <$fh> to read from a socket? Because, it is failing straight away without doing lot of magic(stuffs) in the code.

Server side 
while(@ready = $sel->can_read) {
        if($fh == $lsn) {
            # Accept the socket
            $new = $lsn->accept;
            $sel->add($new);
            print "New client accepted\n";

            print $new "abc\n";
            print $new "abcd\n";
            print $new "abcde\n";
            print $new "abcdef\n";
        }
         else {
            # Process socket
            $a = <$fh> ;
             if (not defined $a)  {
                $sel->remove($fh);
                $fh->close;
                print "Client closed\n";
             }
             else  {
                print $a;
             }
         }
}

Client side 
while(@ready = $sel->can_read) {
    foreach $fh (@ready) {
        my $rr = <$fh>;
        
        exit if ( not defined $rr );
        print $rr;
    }
}

In the above sample, client is receiving only abc(first message) sent by server. When server quits, can_read is returning and client is receiving the remaining messages, not blocking. Getting messages one after another.

Then, I tried with sysread as suggested here. When using sysread, should I read byte by byte till '\n'? Because, I don't know the size of the message. Is it a good way to read byte by byte, do concatenation and then process the message?(I don't think so.)

Please, explain me some way to write a error free way(pleasant way too) to receive messages in socket.. or let me know what am I doing wrong.

Thanks.
