NAME
     machine_info - get information about the running system

SYNOPSIS
     #include <machineinfo.h>
     int machineinfo (command)
     int command;

DESCRIPTION
     machineinfo is an interface for getting information about
     the current system.  It is intended to be used by commands
     to determine what type or class of system is running, since
     it is possible to run the same object code on all types of
     Mips hardware.

     The command argument specifies which information is
     requested, such as the type of the machine or the class of
     the machine.  See the machine_info.h include file for the
     currently-supported set of commands.

     The return value is the information requested.  If the com-
     mand is not supported, the return value is -1.  In all other
     cases, the value will be as described by definitions found
     in the include file or be an integer value as appropriate
     (e.g., in the future, there may be a command to obtain the
     number of megabytes of system memory).

     Information that has been requested is saved as static data
     so that multiple calls to machineinfo simply return the
     data.

     As the system evolves, with new system calls and other means
     of getting dynamic system information, machineinfo will
     present a consistent interface for obtaining certain useful
     items, instead of requiring programmers to deal with more
     system calls with various interfaces.
