101/* EXAMPLES TO END OF FILE
102
103# Examples of notify hooks.  A notify is a generic way for a kernel
104# subsystem to send event notification to userland.
105
106# Here are some examples of ACPI notify handlers.  ACPI subsystems that
107# generate notifies include the AC adapter, power/sleep buttons,
108# control method batteries, lid switch, and thermal zones.
109#
110# Information returned is not always the same as the ACPI notify
111# events.  See the ACPI specification for more information about
112# notifies.  Here is the information returned for each subsystem:
113#
114# ACAD:            AC line state (0 is offline, 1 is online)
115# Button:          Button pressed (0 for power, 1 for sleep)
116# CMBAT:           ACPI battery events
117# Lid:             Lid state (0 is closed, 1 is open)
118# Suspend, Resume: Suspend and resume notification
119# Thermal:         ACPI thermal zone events
120#
121# This example calls a script when the AC state changes, passing the
122# notify value as the first argument.  If the state is 0x00, it might
123# call some sysctls to implement economy mode.  If 0x01, it might set
124# the mode to performance.
