You are right about this, we started off trying to be as ruthless as possible in taking things out of the APIs. The shared memory interfaces were one of those things that I was not sure about so I followed the old adage - "When in doubt, leave it out". The POSIX 1003.13 Real Time Profiles document adds shared memory objects and memory mapped files to its Realtime Controller profile. This is roughly equivalent to our level 2. I still need time to evaluate these profiles against EL/IX, but we might end up with the shared memory stuff at level 2. I have provisionally moved all the shared memory stuff into level 3 in my current working version of the spec. -- Nick Garnett Red Hat, Cambridge, UK
