select() is not implemented in the current version of the socket API. This
will be implemented in a future version. At the moment, you can use threads
to simultaneously serve several clients (see sctpmultiserver.cc for a
complete C++ example).

This is possible if sctpd is used instead of the original sctplib. The sctpd
server contains the sctplib instance. sctpd clients use this single instance
via this server.
Note: The socket API has not been tested with sctpd yet!

Which client program do you use? If you use "sctpterminal" in the
socket_programs directory, the Ctrl-C signal is intercepted by the program
(using a signal handler) and a clean shutdown is made. If you use "terminal",
Ctrl-C immediately stops the program and therefore the complete SCTP
instance. A shutdown is not sent to the server and so it does not recognise
the terminal program's removal.
