I think that you're supposed to be able to use _POSIX_THREAD_PROCESS_SHARED from <unistd.h> or from the CLI, getconf _POSIX_THREAD_PROCESS_SHARED. However, certain platforms such as Mac OS X return a value for this but don't actually implement the feature. I have some autoconf tests which can detect if PTHREAD_PROCESS_SHARED is available and functional, if you're interested. cheers, Luke.
