sysmon_pswitch_unregister
SYSMON_PSWITCH(9) BSD Kernel Developer's Manual SYSMON_PSWITCH(9)
NAME
sysmon_pswitch -- framework for power switches
SYNOPSIS
#include <dev/sysmon/sysmonvar.h>
int
sysmon_pswitch_register(struct sysmon_pswitch *smpsw);
void
sysmon_pswitch_unregister(struct sysmon_pswitch *smpsw);
void
sysmon_pswitch_event(struct sysmon_pswitch *smpsw, int event);
DESCRIPTION
The machine-independent sysmon_pswitch provides a framework for power management. The interface has been largely superceded by the pmf(9)
framework, but sysmon_pswitch is still used to manage power switches as well as related mechanical adapters and buttons. These are encapsu-
lated in the following structure:
struct sysmon_pswitch {
const char *smpsw_name; /* power switch name */
int smpsw_type; /* power switch type */
LIST_ENTRY(sysmon_pswitch) smpsw_list;
};
Unsurprisingly, smpsw_name specifies the name of the power switch and smpsw_type defines the type of it. The following types are defined:
PSWITCH_TYPE_POWER
PSWITCH_TYPE_SLEEP
PSWITCH_TYPE_LID
PSWITCH_TYPE_RESET
PSWITCH_TYPE_ACADAPTER
PSWITCH_TYPE_HOTKEY
If the type is PSWITCH_TYPE_HOTKEY, there are few predefined names that can be used for smpsw_name:
PSWITCH_HK_DISPLAY_CYCLE display-cycle
PSWITCH_HK_LOCK_SCREEN lock-screen
PSWITCH_HK_BATTERY_INFO battery-info
PSWITCH_HK_EJECT_BUTTON eject-button
PSWITCH_HK_ZOOM_BUTTON zoom-button
PSWITCH_HK_VENDOR_BUTTON vendor-button
Once a power switch event has been proceeded, sysmon_pswitch will inform the user space powerd(8), which will possibly execute a script
matching the type of the power switch.
FUNCTIONS
After the sysmon_pswitch structure has been initialized, a new power switch device can be registered by using sysmon_pswitch_register(). The
device can be detached from the framework by sysmon_pswitch_unregister().
The sysmon_pswitch_event() is used to signal a new power switch event. There are two possibilities for the value of event:
PSWITCH_EVENT_PRESSED A button has been pressed, the lid has been closed, the AC adapter is off, etc.
PSWITCH_EVENT_RELEASED A button has been released, the lid is open, the AC adapter is on, etc.
The corresponding events in powerd(8) are pressed and released.
