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.
