dear lksctp Project, i met a problem about sending abort chunk. if you have time, please help me. i'm using the lksctp to develop my function, which is for sending Abort chunk. platform of my development : Redhat centos 5.5 and verion of linux kernel is 2.18. according to "man sctp_sendmsg", just set flags to SCTP_ABORT. my partial code.--------------------------------------------------------------------------------------------------------------------------struct msghdr msg;struct cmsghdr cmsg; struct iovec iov; static char error_code= 12; iov.iov_base = &error_code; iov.iov_len = 1;cmsg.cmsg_level = IPPROTO_SCTP;cmsg.cmsg_type = SCTP_SNDRV;cmsg.cmsg_len = sizeof(struct cmsghdr);msg.msg_name = (SOCKADDR*)&serAddr; msg.msg_namelen = sizeof(serAddr); msg.msg_iov = &iov; msg.msg_iovlen = 1; msg.msg_control = &cmsg; msg.msg_controllen = sizeof(cmsg); ret = sctp_sendmsg(sock_fd, (void*)&msg, sizeof(msg), (SOCKADDR*)&serAddr, sizeof(serAddr),sri.sinfo_ppid, (SCTP_ABORT), sri.sinfo_stream, sri.sinfo_timetolive,sri.sinfo_context);--------------------------------------------------------------------------------------------------------------------but the ret < 0 and the errno is 22 that is invalid agument.please tell which argument is error and how to set cause of abort chunk into "struct msghdr" best regardsthank you fangmin.cao -- To unsubscribe from this list: send the line "unsubscribe linux-sctp" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
