NAME

       memscroller - scrolls a dump of its own RAM across the screen


SYNOPSIS

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


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.

       -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 dis-
               play 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 100000, or about 1/10th second.


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.
