Use a pthread_condition variable with a timeout value equal to
your timeout value (granted, you have to take the absolute time
and map it to relative time)
post to this condition to prematurely wake it up... It'll wake up
on it's own if the timeout expires.
(That is, if the pthread-win32 implements the timeout on condition
variables ;^)

What I meant by sleeping was the thread has called sleep(999).
I would hate to have to put it in some kind of a polling loop.
I guess we'll have to investigate rewriting this to use seg_wait() instead,
thanks for the tip!
Cheers,
Roy

What do you mean by "sleeping"?
If you are blocked on a socket, then use a timeout for the
socket and check a flag to see if you should quit, else, block
on the socket again.
Otherwise, use a synchronization object, such as a semaphore
to "sleep" and post to it to wake it up.
pthread_kill involves signal handling which does not map well
to win32.

I'm trying to port some code that was using pthread_kill() to wake up a
sleeping thread.
Is there some other means of doing this with this implementation of
pthreads, since it doesn't support pthread_kill() ?
Thanks,
Roy
