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.
