<span class="emphasis"><em>kcontrol</em></span> -- the code for which control to read
</p>
<p>
<span class="emphasis"><em>knum</em></span> -- the number of the which Wiimote to
access, which defaults to the first one.
</p>
<p>
On each access a particular data item of the Wiimote is read.
The currently implemented controls are given below, together with
the macro name defined in the file <span class="emphasis"><em>wii_mac</em></span>:
</p>
<p>
0 (WII_BUTTONS): returns a bit pattern for all buttons that were pressed.
</p>
<p>
1 (WII_TWO): returns 1 if the button has just been pressed, or 0 otherwise.
</p>
<p>
2 (WII_ONE): as above.
</p>
<p>
3 (WII_B): as above.
</p>
<p>
4 (WII_A): as above.
</p>
<p>
5 (WII_MINUS): as above.
</p>
<p>
8 (WII_HOME): as above.
</p>
<p>
9 (WII_LEFT): as above.
</p>
<p>
10 (WII_RIGHT): as above.
</p>
<p>
11 (WII_DOWN): as above.
</p>
<p>
12 (WII_UP): as above.
</p>
<p>
13 (WII_PLUS): as above.
</p>
<p>
If the control number is 100 more than one of these button codes then
the current state of the button is returned. Macros with names
like WII_S_TWO etc are defined for this.
</p>
<p>
If the control number is 200 more than one of these button codes then
the return value is 1 if the button i held and 0 otherwise. Macros with names
like WII_H_TWO etc are defined for this.
</p>
<p>
If the control number is 300 more than one of these button codes then
the value is 1 if the button has just been released, and 0 otherwise.
Macros with names like WII_R_TWO etc are defined for this.
</p>
<p>
20 (WII_PITCH): The pitch of the Wiimote. The value is in
degrees between -90 and +90, unless modified by a <span class="emphasis"><em>wiirange</em></span> call.
</p>
<p>
21 (WII_ROLL): The roll of the Wiimote. The value is in
degrees between -90 and +90, unless modified by a <span class="emphasis"><em>wiirange</em></span> call.
</p>
<p>
23 (WII_FORCE_X): The force applied to the Wiimote in the three axes.
</p>
<p>
24 (WII_FORCE_Y):
</p>
<p>
25 (WII_FORCE_Z):
</p>
<p>
26 (WII_FORCE_TOTAL): The total magnitude of the force applied to
the Wiimote.
</p>
<p>
27 (WII_BATTERY): The percent of the battery that remains.
</p>
<p>
28 (WII_NUNCHUK_ANG): The angle of the nunchuk joystick in degrees.
</p>
<p>
29 (WII_NUNCHUK_MAG): The magnitude of the nunchuk joystick from neutral.
</p>
<p>
30 (WII_NUNCHUK_PITCH): The pitch of the nunchuk in degrees, in
range -90 to +90 unless modified by a <span class="emphasis"><em>wiirange</em></span> call.
</p>
<p>
31 (WII_NUNCHUK_ROLL): The roll of the nunchuk in degrees, in
range -90 to +90 unless modified by a <span class="emphasis"><em>wiirange</em></span> call.
</p>
<p>
33 (WII_NUNCHUK_Z): The state of the nunchuk Z button.
</p>
<p>
34 (WII_NUNCHUK_C): The state of the nunchuk C button.
</p>
<p>
35 (WII_IR1_X): The infrared pointing of the Wiimote.
