* mode.c - mechanisms for dealing with SGI-style modal displays.
*
* There are four generally-understood useful modes for status displays
* of the sort exemplified by the IRIX ``netstat -C'' and ``osview''
* programs. We try to follow their example, although the user interface
* and terminology slightly differ.
*
* RATE - the default mode - displays the precise rate of change in
* each statistic in units per second, regardless of the actual display
* update interval.
*
* DELTA - displays the change in each statistic over the entire
* display update interval (i.e., RATE * interval).
*
* SINCE - displays the total change in each statistic since the module
* was last initialized or reset.
*
* ABSOLUTE - displays the current value of each statistic.
*
* In the SGI programs, these modes are selected by the single-character
* commands D, W, N, and A. In systat, they are the slightly-harder-to-type
* ``mode delta'', etc. The initial value for SINCE mode is initialized
* when the module is first started and can be reset using the ``reset''
* command (as opposed to the SGI way where changing modes implicitly
* resets). A ``mode'' command with no arguments displays the current
* mode in the command line.
