i have already tried the second function in the following manner

        # print "\nCalling recv()...";
        my $select = IO::Select->new();
        $select->add(LINK_HNDL);
        if($select->can_read(0))
        {
            recv(LINK_HNDL, $temp, $size - length($data), $flags);
            #print "**$temp**\n";
        }
        else
        {
            #print "No data on socket.\n";
        }

instead of normal recieve call, but result is the application/server on board is getting slower, even during a healthy run. timeout is getting detected.

so what i want is, some way of setting recv so that it won't block when server is dead(not sure of this term,I mean switching off server(board on which it is running)abruptly).
