The Single UNIX Specification, Version 3 was released recently, incorporating POSIX 1003.1-2001. I think the standard is available for free (unlike the older POSIX standards) on the web: http://www.unix-systems.org/version3/ > > The RT stuff is the one listed; the AIO stuff, I'd have to > look up; have you found it yet? Or do I need to go diving? The AIO stuff looks to be there in FreeBSD for the most part. Unfortunately in ACE, there is a interdependency between the AIO code and RT signals, so you either have to have all the features implemented, or you can't use any of them. Is there a maintainer or set of maintainers who looks at POSIX stuff for FreeBSD? I notice that in /usr/src/sys/posix4/, there is some code for things like POSIX message queues. Is that code maintained, or has it been deprecated in favor of kqueue? I don't want to get into a debate about the technical merits of POSIX, but I have worked on some projects where adhering to POSIX api's was actually a project requirement due to customer demand.
