Dear all,

you find C programs in sctplib/socket_programs. The documenation is
http://www.ietf.org/internet-drafts/draft-ietf-tsvwg-sctpsocket-04.txt

TCP_combined_server.c
A multithreaded server providing chargen, discard, echo and daytime
services using the TCP like API.

UDP_combined_server.c
A server providing chargen, discard, echo and daytime
services using the UDP like API.

idexampletcp.c
The TCP like API example from the ID (internet draft).

idexampletcp.c
The UDP like API example from the ID (internet draft).

Best regards
Michael
