Hi all

problem with my perl =>

creating a IO::Socket::INET handle, when i call $handle->recv(....) it
doesnt seem to block?? anyone know about this?

works perfectly in 5.6.0 (activeperl, perl built for linux, and HP-UX)

I presume that its something to do with cygwin's 'c' recv() function

any help/hints welcome!!

Simon.



=======================================

versions and full code are below for anyone interested

perl version:
    v5.6.1 built for cygwin

works with
    v5.6.0 built for MSWin32-x86-multi-thread
    v5.6.0 built for 9000/777-hpux

IO::Socket::INET version (all OSs) 1.25

sub _connect
{
        my $self=shift;
        my $interface=$self->{interface};
        my %info=(Proto     => "tcp",
                  PeerAddr  => $self->{ip_address},
                  PeerPort  => $self->{port},
                        );
        p_debug("interface for $self->{name} [$self->{alias}] is
\"$interface\"...");
        my $handle=$self->_check_for_registered_connection(%info,
                                        interface => $interface,
                                );

        if (! $handle)
        {
                p_user("open connection to inst_daemon ...");
                $handle = IO::Socket::INET->new(%info,
                                                   Timeout => 4);
                die "Could not connect to $self->{ip_address}:$self->{port}
via $interface" unless $handle;
                p_user("connected successfully\n\n");

                $handle->autoflush(1);
                $self->_register_connection(%info,
                                        interface => $interface,
                                        handle => $handle
                                        );
        }
        else
        {
                p_user("reusing existing connection\n");
        }

        $self->{connection}=$handle;

        my $response;
        print $handle "5%:SENS:DATA:TEL:TEST?";
        $handle->recv($response,1000);
        print "GOT:: : $response\n";

}
