I have an SOCK_SEQPACKET socket and want to setup an association without sending a message. The background is that I want to keep the round-trip times of peer servers. I've enabled regular heartbeat and can use SCTP_GET_PEER_ADDR_INFO to get the RTT. But in case a host is down or services are restarted I don't have an association to ask, so I will need some way to (re)establish associations. This is done in a different thread as the normal socket operation, which uses EOR to write. If I send a (dummy)message to the socket I would have to add a mutex to not disturb the sending thread. -- B.Walter <bernd@bwct.de> http://www.bwct.de Modbus/TCP Ethernet I/O Baugruppen, ARM basierte FreeBSD Rechner uvm.
