SYNOPSIS

       memscroller  [--display host:display.screen] [--window] [--root] [--window-id number][--mono] [--install]
       [--visual visual] [--font font] [--delay int] [--mono | -color]  [--ram  |  -random  |  --filename  file]
       [--fps]

DESCRIPTION

       The  memscroller  program  scrolls a dump of its own process memory across the screen in three windows at
       three different rates.

OPTIONS

       memscroller accepts the following options:

       --window
               Draw on a newly-created window.  This is the default.

       --root  Draw on the root window.

       --window-id number
               Draw on the specified window.

       --install
               Install a private colormap for the window.

       --visual visual
               Specify which visual to use.  Legal values are the name of a  visual  class,  or  the  id  number
               (decimal or hex) of a specific visual.

       --color Render each three bytes of memory as R, G, B.  This is the default.

       --mono  Render each byte of memory in shades of green.

       --ram   Read from the process's address space.  This is the default.

       --random
               Instead of reading from memory, generate random numbers.

       --filename file
               Instead of reading from memory, read from the given file until EOF, then re-open it.  If you have
               permission, /dev/mem is an interesting choice here.  (Note  that  /dev/null  won't  ever  display
               anything, because it returns EOF without ever returning any data.)

       --delay microseconds
               How much of a delay should be introduced between steps of the animation.  Default 10000.

       --fps   Display the current frame rate and CPU load.

ENVIRONMENT

       DISPLAY to get the default host and display number.

       XENVIRONMENT
               to  get  the  name  of  a  resource  file  that  overrides  the  global  resources  stored in the
               RESOURCE_MANAGER property.

       XSCREENSAVER_WINDOW
               The window ID to use with --root.
