Awesome!
That did the trick! :) I did try -lsocket as a guess...

You probably need to link to -lnetwork ....

I’m looking to write a very simple terminal app that opens a TCP
connection, sends some data, and closes again. Is there any sample code I
can leech? :)
Isn't this actually off topic?

Just to explain better... :)
I’m trying to write a simple client app for HaikuOS that sends some data to
a remote server via TCP. I downloaded some generic C code (below), but I
get the following error when I compile it. Am I missing some headers?
