21. /proc/acpi/hotkey/event_config
3(event based hotkey or event config interface):
4a. add a event based hotkey(event) :
5echo "0:bus::action:method:num:num" > event_config
6
7b. delete a event based hotkey(event):
8echo "1:::::num:num" > event_config
9
10c. modify a event based hotkey(event):
11echo "2:bus::action:method:num:num" > event_config
12
132. /proc/acpi/hotkey/poll_config
14(polling based hotkey or event config interface):
15a.add a polling based hotkey(event) :
16echo "0:bus:method:action:method:num" > poll_config
17this adding command will create a proc file
18/proc/acpi/hotkey/method, which is used to get
19result of polling.
