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.
