Hi Feiyang,

what about using

      int sctp_send(int sd,

                    const void *msg,
                    size_t len,

                    const struct sctp_sndrcvinfo *sinfo,
                    int flags);

and provide the assoc_id in

  struct sctp_sndrcvinfo {
     uint16_t sinfo_stream;
     uint16_t sinfo_ssn;
     uint16_t sinfo_flags;
     uint16_t sinfo_pr_policy;
     uint32_t sinfo_ppid;
     uint32_t sinfo_context;
     uint32_t sinfo_pr_value;
     uint32_t sinfo_tsn;
     uint32_t sinfo_cumtsn;
     sctp_assoc_t sinfo_assoc_id;
  };

Sorry for not being clear...

Best regards
Michael

HI Michael.
the sctp_sendmsg's prototype is:
ssize_t sctp_sendmsg(int sd,
                        const void *msg,
                        size_t len,
                        const struct sockaddr *to,

                        socklen_t tolen,
                        uint32_t ppid,
                        uint32_t flags,
                        uint16_t stream_no,
                        uint32_t pr_value,

                        uint32_t context);
how can i provide association ID in it? I just learn about the sctp_sendmsg may be a wrapper of sendmsg.
do you mean change the source code of sctp_sendmsg?

Hi Feiyang,

this is a known bug^H^H^Hfeature of the Solaris SCTP implementation. You have to provide
the association ID in the sctp_sendmsg() call.

Best regards

hi guys.
  i have a problem in solaris 10. I create a one-to-many sctp socket and call sctp_sendmsg to server. the server return from sctp_recvmsg, and send back the message. when the server send back message, i encounter a error:Address already in used.
i think this may be a bug. do you think so?
