Thanks!
If sendmsg succedes like this then how its possible to maintain ordering of messages:
Consider below order:
  send1 ----> send2

send1 was not recieved but send2 was successfully recived by peer on same association. Application gets a notification of send1 (indicating send failed).



Regards,
Rahul
