13 This demo program utilizes joysticks 0 and 1 in graphics mode.
14 If you specify a joystick number, only this is used. The demo separates
16 the screen in two parts where you can move a cursor around with the
17 resp. joystick. Pressing button 2 changes the color, pressing button 1
18 draws.
19 It also prints the current joystick position to the screen.
21 Internally the demo also shows the use of custom joystick handlers and
23 how to recalibrate a joystick in graphics mode (press key <1> and <2>
24 respectively.
25 After the demo runs and the joysticks are initialized it is possible to
27 share the joysticks with another application (as long as it releases
28 the joysticks upon a VC switch as well).
29 Pressing <Q> exits.

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

41 This demo is part of svgalib and can be found in the demos/ subdirec‐
42 tory of the original svgalib distribution. However, it is not installed
43 in the system by default, s.t. it is unclear where you can find it if
44 your svgalib was installed by some linux distribution. Even then, when
45 you have the demo on your system, you probably won't have the sources
46 s.t. it is only of limited use for you.
47 In case of any such problem, simply get an svgalib distribution from
49 the net. You even don't need to install it. Just make in the demos/
50 subdirecty. As of this writing, svgalib-1.3.0.tar.gz is the latest ver‐
51 sion and can be retrieved by ftp from sunsite.unc.edu at
52 /pub/Linux/libs/graphics and tsx-11.mit.edu at /pub/linux/sources/libs
53 which will most probably be mirrored by a site close to you.

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

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