Dear Jun,

you can not use fork with our library. The reason is the follwing:

The SCTP implementation is part of your (unix) process. If you fork
an exiting one you have two SCTP engines serving the same association.
This does not work.

If you use our socket-API you can use multiple threads instead of multiple
processes. You can find an example for that in
sctplib/socket_programs/TCP_combined_server.c

The only possibility would be using the sctpd and extend the sctpdlib
to support fork. Since sctpd is no longer supported by their developers
you would be on your own. Since the multithreaded approach is supported
we do not have any plans to support fork in the (near) future.

Best regards
Michael
