IEEE 1003.1d-1999

This work activity will extend the system interfaces defined by 1003.1 (as amended by 1003.1b, 1003.1c, and 1003.1i) to include the following additional facilities required by realtime applications: an efficient process creation mechanism, additional realtime scheduling policies, interfaces for execution time monitoring, interfaces for interacting with special devices, interfaces for improving I/O performance, and timeouts for blocking functions. This standard will not change the base standard which it amends (including any existing amendments) in such a way as to cause implementations or strictly conforming applications to no longer conform.
