.Dd January 6, 2015 .Dt SYSMON_PSWITCH 9 .Os .Sh NAME .Nm sysmon_pswitch .Nd framework for power switches .Sh SYNOPSIS n dev/sysmon/sysmonvar.h .Ft int .Fn sysmon_pswitch_register "struct sysmon_pswitch *smpsw" .Ft void .Fn sysmon_pswitch_unregister "struct sysmon_pswitch *smpsw" .Ft void .Fn sysmon_pswitch_event "struct sysmon_pswitch *smpsw" "int event" .Sh DESCRIPTION The machine-independent .Nm provides a framework for power management. The interface has been largely superceded by the .Xr pmf 9 framework, but .Nm is still used to manage power switches as well as related mechanical adapters and buttons. These are encapsulated in the following structure: d -literal struct sysmon_pswitch { const char *smpsw_name; /* power switch name */ int smpsw_type; /* power switch type */ LIST_ENTRY(sysmon_pswitch) smpsw_list; }; .Ed
p Unsurprisingly, .Fa smpsw_name specifies the name of the power switch and .Fa smpsw_type defines the type of it. The following types are defined:
p l -tag -width PSWITCH_HK_VENDOR_BUTTON -compact -offset indent t PSWITCH_TYPE_POWER t PSWITCH_TYPE_SLEEP t PSWITCH_TYPE_LID t PSWITCH_TYPE_RESET t PSWITCH_TYPE_ACADAPTER t PSWITCH_TYPE_HOTKEY t PSWITCH_TYPE_RADIO .El
p If the type is .Dv PSWITCH_TYPE_HOTKEY , there are few predefined names that can be used for .Fa smpsw_name :
p l -tag -width PSWITCH_HK_VENDOR_BUTTON -compact -offset indent t PSWITCH_HK_DISPLAY_CYCLE .Em display-cycle t PSWITCH_HK_LOCK_SCREEN .Em lock-screen t PSWITCH_HK_BATTERY_INFO .Em battery-info t PSWITCH_HK_EJECT_BUTTON .Em eject-button t PSWITCH_HK_ZOOM_BUTTON .Em zoom-button t PSWITCH_HK_VENDOR_BUTTON .Em vendor-button .El
p Once a power switch event has been proceeded, .Nm will inform the user space .Xr powerd 8 , which will possibly execute a script matching the type of the power switch. .Sh FUNCTIONS After the .Em sysmon_pswitch structure has been initialized, a new power switch device can be registered by using .Fn sysmon_pswitch_register . The device can be detached from the framework by .Fn sysmon_pswitch_unregister .
p The .Fn sysmon_pswitch_event is used to signal a new power switch event. There are two possibilities for the value of .Fa event : l -tag -width PSWITCH_HK_VENDOR_BUTTON -offset indent t PSWITCH_EVENT_PRESSED A button has been pressed, the lid has been closed, the AC adapter is off, etc. t PSWITCH_EVENT_RELEASED A button has been released, the lid is open, the AC adapter is on, etc. .El
p The corresponding events in .Xr powerd 8 are .Em pressed and .Em released . .Sh SEE ALSO .Xr powerd 8 , .Xr pmf 9 , .Xr sysmon_envsys 9 , .Xr sysmon_taskq 9 .Sh AUTHORS .An Jason R. Thorpe Aq Mt thorpej@NetBSD.org
