     21RTEMS supports a number of POSIX process, user, and group oriented
     22routines in what is referred to as a "SUSP" (Single-User, Single
     23Process) manner.  RTEMS supports a single process, multithreaded
     24POSIX 1003.1b environment.  In a pure world, there would be
     25no reason to even include routines like @code{getpid()} when there
     26can only be one process.  But providing routines like @code{getpid()}
     27and making them work in a sensible fashion for an embedded environment
     28while not returning ENOSYS (for not implemented) makes it significantly
     29easier to port code from a UNIX environment without modifying it.
