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 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.
