eventtest(6) Svgalib User Manual eventtest(6)NAMEeventtest - test the waitevent function of svgalib
This is a kind of an upgraded keytest(6) and mousetest(6) demo using
the vga_waitevent(3) function.
Use mouse to move cursor. <1>-<9>, <0> to set the cursor size.
<Space> to change the cursor color. Left button to draw. Right button
or <Q> to bailout.
The cursor goes on/off every half second by usage of a timeout passed
to vga_waitevent(3). Every 5 seconds a string from a child process
(the time) arrives asynchronously and is displayed by the frontend.
This comes in through a pipe(2) which is monitored by vga_waitevent(2).
You can set a videomode to use by setting the environment variable
SVGALIB_DEFAULT_MODE to a number (see vgatest for a list) or a string
like G0x1x2 where you replace 0 with desired x resolution, 1 with the
desired y rez, and 2 with the desired number of colors (2, 16, 256,
32K, 64K, 16M, 16M4). Again, only certain choices are available, see
vgatest for a list.
In case nothing is selected, G320x200x256 is choosen.
This demo is part of svgalib and can be found in the demos/ subdirec‐
tory of the original svgalib distribution. However, it is not installed
in the system by default, s.t. it is unclear where you can find it if
your svgalib was installed by some linux distribution. Even then, when
you have the demo on your system, you probably won't have the sources
s.t. it is only of limited use for you.
In case of any such problem, simply get an svgalib distribution from
the net. You even don't need to install it. Just make in the demos/
subdirecty. As of this writing, svgalib-1.2.12.tar.gz is the latest
version and can be retrieved by ftp from sunsite.unc.edu at
/pub/Linux/libs/graphics and tsx-11.mit.edu at /pub/linux/sources/libs
which will most probably be mirrored by a site close to you.
