DESCRIPTION

15       The memscroller program scrolls a dump of its own process memory across
16       the screen in three windows at three different rates.
17

OPTIONS

19       memscroller accepts the following options:
20
21       --window
22               Draw on a newly-created window.  This is the default.
23
24       --root  Draw on the root window.
25
26       --window-id number
27               Draw on the specified window.
28
29       --install
30               Install a private colormap for the window.
31
32       --visual visual
33               Specify  which  visual  to use.  Legal values are the name of a
34               visual class, or the id number (decimal or hex) of  a  specific
35               visual.
36
37       --color Render  each three bytes of memory as R, G, B.  This is the de‐
38               fault.
39
40       --mono  Render each byte of memory in shades of green.
41
42       --ram   Read from the process's address space.  This is the default.
43
44       --random
45               Instead of reading from memory, generate random numbers.
46
47       --filename file
48               Instead of reading from memory, read from the given file  until
49               EOF,  then  re-open it.  If you have permission, /dev/mem is an
50               interesting choice here.  (Note that /dev/null won't ever  dis‐
51               play  anything,  because  it returns EOF without ever returning
52               any data.)
53
54       --delay microseconds
55               How much of a delay should be introduced between steps  of  the
56               animation.  Default 10000.
57
58       --fps   Display the current frame rate and CPU load.
59

ENVIRONMENT

61       DISPLAY to get the default host and display number.
62
63       XENVIRONMENT
64               to  get  the  name of a resource file that overrides the global
65               resources stored in the RESOURCE_MANAGER property.
66
67       XSCREENSAVER_WINDOW
68               The window ID to use with --root.
