I am writing an application using TCP sockets, I don't know the IP
address of the server and am thinking of using a broadcast to find it.

I am using these examples as a test.
http://www.ecst.csuchico.edu/~beej/...amples/server.c
http://www.ecst.csuchico.edu/~beej/...amples/client.c

How do you modify these so the client will do a broadcast.
I had a guess at using use SO_BROADCAST in programs but it doesn't
appear to change anything.

Thanks
Neil

Read the "Broadcasting" chapter of "Unix Network Programming, Vol.1"

If you're serious about network programming, you really should get that
book.  It's a comprehensive source of answers to many questions about
network programming.

I have found the answer, after doing a search and looking though a lot
of WEB pages, I found a hint that I needed to use UDP instead.  After
some experiments I got it to work.
