       mjoytest  -  test the svgalib joystick package in graphics

       mjoytest [-j joystick] [[-m] video mode]

       This demo program utilizes joysticks 0 and 1  in  graphics

       If  you  specify a joystick number, only this is used. The
       demo separates the screen in two parts where you can  move
       a cursor around with the resp. joystick. Pressing button 2
       changes the color, pressing button 1 draws.

       It also  prints  the  current  joystick  position  to  the

       Internally  the demo also shows the use of custom joystick
       handlers and how to recalibrate  a  joystick  in  graphics
       mode (press key <1> and <2> respectively.

       After  the  demo runs and the joysticks are initialized it
       is possible to share the joysticks with  another  applica-
       tion  (as  long  as  it  releases  the joysticks upon a VC
       switch as well).

       Pressing <Q> exits.

       After a vc switch the demo occasionally hangs in vga_wait-
       event(3) not timing out (hence the joysticks block). It is
       not clear if it  is  a  conceptional  problem  or  bug  in
       vga_waitevent(3)  or  the kernel.  Simply press any key to
       revive the demo.

       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-1.3.0.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.

       The  functions used by this demo are only available in ELF
       versions of svgalib. Due to backwards compatibility issues
       it cannot be used with shared a.out libs.

       The  svgalib  joystick  handler  was mostly done by Daniel
       Engstr\"om <daniel.engstrom@riksnett.no>.   Multiple  joy-
       stick,  VC  switching  support  and  code  to glue it into
       svgalib by Michael Weller  <eowmob@exp-math.uni-essen.de>.
       Part  of  the  code  is  based  on  code from C. Smith and
       Vojtech Pavlik.
