       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 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  asyn-
       chronously 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/ 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 distri-
       bution 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 mir-
       rored by a site close to you.
