 NAME
      context - process context

 DESCRIPTION
      The context is a set of character strings associated with each
      process.  Each string corresponds to a characteristic of the machine
      the process is running on.  The strings included in the context of
      every process include:

           o  cnode name

           o  types of executable files that can be run by the hardware

           o  type of cnode (``localroot'' or ``remoteroot'')

           o  the string ``default''

      The process context is used to access context dependent files (see
      cdf(4)).

      Multiple strings may be present in the context that indicate the
      ability to run executable code for the designated hardware.  When two
      or more strings appear in the same context, they appear in the order
      listed.

      Series 300 and 400 strings include:

           HP-MC68040
           HP98248A
           HP-MC68881
           HP98635A
           HP-MC68020
           HP-MC68010

      Valid Series 700 and 800 strings are:

           PA-RISC1.1
           HP-PA

      Note that presence of a string does not mean that the designated
      hardware itself is present.  For example, since the MC68020 processor
      supports a superset of the MC68010 instruction set, processes running
      on a system with an MC68020 processor will have HP-MC68010 in their
      context, as well as HP-MC68020.  The string HP-MC68010 is present on
      all series 300 systems.

      Similarly, since the PA-RISC version 1.1 processor supports a superset
      of the HP-PA (PA-RISC version 1.0) instruction set, processes running
      on a system with a PA-RISC version 1.1 processor will have HP-PA in
      their context, as well as PA-RISC1.1.

 EXAMPLE
      A process running on an HP9000 model 350 workstation, with cnode name
      william could have the following strings in its context:

           william
           remoteroot
           HP-MC68881
           HP-MC68020
           HP-MC68010
           default

      Note that this hardware is capable of running executables with the
      instruction sets for the MC68881, MC68020, and the MC68010.  Every
      process's context ends with the string default.  Also note that the
      system call getcontext(2) and the command getcontext(1) show the
      context as a single string:

           william remoteroot HP-MC68881 HP-MC68020 HP-MC68010 default

 WARNINGS
      Unless an order is specified, users and applications should not depend
      on the order of strings within the context.  However, default is
      always the last string.  Other aspects of this order may vary between
      releases.
