SceSysEventHandler

typedef int(* SceSysEventHandler) (int resume, int event_id, void *event_param, void *args)

System suspend/resume event handler.

Parameters

[in]	resume	- Zero while suspending, or one while resuming.
[in]	event_id	- Event identifier.
[in]	event_param	- Event data supplied to ksceKernelSysEventDispatch.
[in]	args	- Private argument supplied when registering the handler.

Returns

0 on success, < 0 on error.

Function Documentation

ksceKernelPowerTick()

int ksceKernelPowerTick

(

SceKernelPowerTickType

type

)

Cancel specified idle timers to prevent entering in power save processing.

Parameters

[in]

type

- One of SceKernelPowerTickType

Returns

0

ksceKernelRegisterSysEventHandler()

int ksceKernelRegisterSysEventHandler	(	const char *	name,
		SceSysEventHandler	handler,
		void *	args
	)

Register system event handler.

Parameters

[in]	name	- Name of handler
[in]	handler	- The handler
[in]	args	- Handler arguments

Returns

0 on success, < 0 on error.

ksceKernelSysEventDispatch()

int ksceKernelSysEventDispatch	(	SceBool	resume,
		SceUInt32	event_id,
		void *	event_param,
		SceUID *	failed_handler_id
	)

Call registered handlers for a suspend or resume event.

If a handler fails and failed_handler_id is non-NULL, stop calling handlers and write the failing handler's UID to *failed_handler_id. If failed_handler_id is NULL, continue calling handlers after failures and return the last handler's result.

Parameters

[in]	resume	- Zero while suspending, or one while resuming.
[in]	event_id	- Event identifier.
[in]	event_param	- Event data passed to each handler that is called.
[out]	failed_handler_id	- Optional output for the first failing handler UID.

Returns

The result from the last handler called, or 0 when no handler is registered.

ksceKernelUnregisterSysEventHandler()

int ksceKernelUnregisterSysEventHandler

(

SceUID

handler_id

)

Unregister a system event handler.

Parameters

[in]

handler_id

- UID returned by ksceKernelRegisterSysEventHandler.

Returns

0 on success, < 0 on error.
