The way that you can check for this is to test for the preprocessor constant _POSIX_THREAD_PRIORITY_SCHEDULING. "The POSIX standards are flexible, because they're designed to be useful in a wide range of environments. In particular, since traditional UNIX systems don't support any form of realtime scheduling control, all of the tools for controlling realtime response are optional. The fact that a given implementation of UNIX 'conforms to 1003.1c-1995' does not mean you can write predictable realtime programs." -- David R.
