       eventtest - 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 but-
       ton 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  vgat-
       est  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/ subdirectory 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   at   /pub/Linux/libs/graphics   and    at
       /pub/linux/sources/libs which will most probably be mirrored by a site close to you.

       vga_waitevent(3) function is due to him.
