mjoytest(3)		      Svgalib User Manual		   mjoytest(3)

NAME
       mjoytest	- test the svgalib joystick package in graphics	mode

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

DESCRIPTION
       This demo program utilizes joysticks 0 and 1 in graphics	mode.

       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 screen.

       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 application (as long	as it releases
       the joysticks upon a VC switch as well).

       Pressing	<Q> exits.

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

NOTES
       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-1.3.0.tar.gz is the latest ver-
       sion   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.

CAVEATS
       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.

AUTHOR
       The  svgalib  joystick  handler	was  mostly  done by Daniel Engstr\"om
       <daniel.engstrom@riksnett.no>.  Multiple	joystick, 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.
