[Lksctp-developers] association Id

[Mike L. <mik...@ya...>]

Hi,
 
I have one basic question regarding lksctp.
From socket API document, if the SCTP_ASSOC_CHANGE event is enabled, then the sac_assoc_id will be availabe from SCTP_COMM_UP notification. This document also mentions tha tall the nofitication for a given association have the same association identifier. I have the following question:
 
1. can this association identifier(as part of sctp_sndrcvinfo) be used in sendmsg(), and not use the specific destination address since which maybe stored by SCTP during the association establishment phase?
2. Will the association identifier(as part of sctp_sndrcvinfo) in rcvmsg() msghdr the same as the one in the notification? If yes, then we don't need to association the tranport address to the association Id.
3. How does the SCTP user know the peer address list at the server side?
 
thanks a lot,
Mike
