Submitted-by: devil@techunix.technion.ac.il (Gil Tene) Hello people, I am interested in knowing the current status of POSIX 1003.4. I have read some articles (quite) a while back, but haven't seen anything new on the subject. Maybe you people out there can help me ? - When is a final version of 1003.4 expected to be adopted ? - What will 1003.4 include ? what sub-1003.4 parts are there ? (e.g. 1003.4a, etc.) - Where/how can I get my hands on the drafts ? - What is the current "trend" in the industry with regard to meeting 1003.4 standards ? How soon can we expect to see 1003.4 support in major releases of vendors ? (SVR4, OSF/1, SunOS, HP-UX, Ultrix, etc.) I think this may be of interest to the entire group (comp.std.unix and comp.realtime). I will summerize any e-mail responses, but would also like to see a more wide-spread discussion. AdvThanks, -- Gil. -- -------------------------------------------------------------------- -- Gil Tene "Some days it just doesn't pay -- -- devil@techunix.technion.ac.il to go to sleep in the morning." -- -------------------------------------------------------------------- Volume-Number: Volume 24, Number 6

There is a snitch report on its way within the week on the status of POSIX.4 after the April meeting in Chicago. > Maybe you people out there can help me ? > - When is a final version of 1003.4 expected to be adopted ? Good question. It really depends on the already strained volunteer resources of its tech editors and tech reviewers. (I'm one of them, so I can say this.) Draft 11 is due out anytime for ballot. Even if the technical content remains relatively untouched, there is still language independent specifications to be written (which I'm responsible for, so yell at me) and test assertions. > - What will 1003.4 include ? what sub-1003.4 parts are there ? > (e.g. 1003.4a, etc.) 1003.4 ------ Draft 9 which went out for ballot in March 1990 contained chapters on the following services: binary semaphores, process memory locking, shared memory, priority scheduling, events, clocks and timers, IPC message passing, synch I/O, asynch I/O, realtime files. Draft 10 ``fixed'' signals to replace events, and added memory mapped files to the shared memory chapter. Draft 11 will likely make major changes to (or remove) IPC, in favour of work being done in POSIX.12 (Protocol Independent Interfaces). 1003.4a ------- Threads interfaces. It is currently in ballot. 1003.4b ------- More real-time interfaces. Descibed in the forthcoming snitch. 1003.13 ------- Realtime Profiles. The group is building a small set of profiles of the realtime interfaces from a scaled down embedded profile up to a kitchen-sink do-everything profile. > - Where/how can I get my hands on the drafts ?

Standard market-speak answers include: i) We're tracking the standard. (Some of them actually are contributing, instead of reading about it in ever changing ballot drafts.) ii) We already have real-time. (Guess who this is. The only problem is that it isn't standard and their eyes glaze over and they become non-commital after that.) iii) We aren't pursuing the realtime market at this time, but if our customers ask for it, we'll provide it. (I've heard one vendor claim not to be pursuing the market in realtime, only to have someone else there express real surprise at this statement when I repeated it in a quiet corner.) I will not risk the wrath of friends and enemies by mentioning products I know of that are seriously implementing the draft document interface, because I'm bound to miss someone and some stuff was non-disclosure material.
