1. In sctpsocketwrapper.cc, about line 1720, replace
if(tdSocket->Socket.SCTPSocketDesc.SCTPAssociationPtr != NULL)) {
by
if((tdSocket->Socket.SCTPSocketDesc.SCTPAssociationPtr != NULL) &&
(tdSocket->Socket.SCTPSocketDesc.ConnectionOriented)) {
This will fix the problem with the blocking recvmsg() call.

2. You program does not access the sctp_sndrcvinfo structure correctly,
therefore it does not print the received stream number correctly. Use
following code:
else{
// struct sctp_sndrcvinfo *sri = (struct sctp_sndrcvinfo
*)CMSG_FIRSTHDR(msg);
struct sctp_sndrcvinfo *sri = (struct sctp_sndrcvinfo *)CMSG_DATA(cmsg);
printf("%d bytes received at stream %d\n",nr,sri->sinfo_stream);
}

I have successfully tested the code with the new version of the socket API
which will be released about end of the week. Please mail whether the bugfix
works or produces more problems.
