Re: Multithreading question

Sorry,
now that im thinking about it more, i think my question was more
directed towards time slicing.  Ive written multi threaded programs
before, but I wasnt quite sure if RTLinux time sliced the same way,
Ive read up some more on threads and RTLinux and from what I gather It
would be quicker to multithread my program since thread creation is
less overhead then processes in general.  I think I was rushing into
the question, what I have is a real time robotics module that was
written without the general philosophy of rtlinux, being, anything
that can be done non real time, should not be done real time
(something to that effect), so Im thinking now that perhaps it would
be more efficient to spawn threads for movement, vision and sensing. 
My next question is , can the sigaction be used with the free rtlinux
or just with pro?

Thanks for the help
Tim
