Do you mean, you are waiting on a condition variable?

When the condition is fullfilled, your thread will run. If the
condition signals cancelation time you should exit your thread.

Thread cancellation is a complicated topic and is not yet covered
by boost thread. That does not mean, you cannot use it. You should
try to design your application in a way that can do without cancellation
support. Some even think foreign cancellation of threads is bad 
design.

If you are new to threading however I would recommend to read
something about the topic beforehand. Getting a book about
the pthreads library (a C library) might be very valuable, since
the boost thread uses quite a couple of ideas from it.
