You are right, even though the states for the paths are already in there,
it makes sense, to add the association states there, as well.

I agree. I will add that !

Ahh, yes of course, you are absolutely right. At one time I had started
doing something of a UDP communication within the library, and used
the internal adl_send_message() function. So I will need to add a send
function for IPC via UDP. Something like:
sctp_sendUdpData(int socket_fd, unsigned char * buf, int len,
unsigned char dest_address[] ,unsigned short
dest_port);

Well and now I am looking forward to getting it *compiled* again :-)

Anyway, thanks for the good comments !
