I am considering using boost.threadfir a project and was wondering whether the function passed to boost.thread has to be of any pargicular type i.e void return.

No. The return type is ignored.

Secondly, if I don't call thread.join, will the thread continue executing?

The thread will stop when the thread function returns. join simply causes the caller to block until the thread finishes.

I'm terminating the thread with a windows event. Finally, is there a terminate function?

There is an interrupt function which causes an exception to be thrown in the thread the next time it reaches an interruption point. In Christ, Steven Watanabe
