Why there is no 'pthread_*' call at all in Thread and ThreadContext? Not even pthread_create? From 24 requirements item in req1588.html, I discovered that 12 of them have been implemented. I added 2 more implemented requirements: created and blocked count. Next I'll tackle the priority related. But.... should I use pthread_*? > -- > Frank V.

If you are running on a SMP machine, the threads that are created using pthread do not take advantage of the other processors.

I also found getpid(), getppid(), and clone() call in Thread.cpp. Maybe we should move them to Environment? Is the Enviroment designed to be a "leaf" module as a wrapper of all the underlying system? If yes, we should not put a call to Thread::getKernelError() in Environment::setupCommonAccess. > > > > > > -- > > > Frank V.

Your right, organize a new static class if you like which covers the behavior you want, we can also use namespaces to localize the context: corelinux::Enviornment corelinux::Enviornment::Process etc. -- Frank V.
