Each section in +this document corresponds to a section in the 1003.1 standard +and the implementation status of the items required by the standard +are listed. + +RTEMS supports a number of POSIX process, user, and group oriented +routines in what is referred to as a "SUSP" (Single-User, Single +Process) manner. RTEMS supports a single process, multithreaded +POSIX 1003.1b environment. In a pure world, there would be +no reason to even include routines like ``getpid()`` when there +can only be one process. But providing routines like ``getpid()`` +and making them work in a sensible fashion for an embedded environment +while not returning ENOSYS (for not implemented) makes it significantly +easier to port code from a UNIX environment without modifying it. + +..
