Is it possible to do this? If so, I would imagine the only way would be
to call close () on the socket right?

What do you mean 'cancel'?

Let's say I call write () on a socket, and the other end of the
connection hangs. I might want to cancel that call. If the write ()
was done in another thread then yet another thread might be able to
cancel the write () call.

You could include the fileio and posix packages and use signals.

I suppose I could, couldn't I! :) Is there any way of targetting a
specific thread only with the signal?

pthread_kill(), or mask the signal in all the other threads.
