The Alarm API allows setting an "alarm clock" for the delivery of a notification at some point in the future.

Required Header

#include <app_alarm.h>

Overview

Mobile devices typically give constant access to information from various sources. Some of this information is best delivered through alarms - the most obvious case is a calendar scheduling application which lets you know when a meeting is about to start. Alarms are certainly better than actively waiting in a loop. They are also better than putting an interface to sleep because they do not block your main UI thread. Use of alarms helps build smooth user experiences and implements unattended data synchronization tasks. If an application is installed after setting the alarm, your alarm is canceled automatically.
When the alarm is expired, Alarm Manager will turn on the LCD to prohibit background jobs. If you want to use alarm API without turning on the LCD, you can use alarm_schedule_after_delay(). There are 3 ways to set an alarm.

FUNCTION	DESCRIPTION
alarm_schedule_once_after_delay()	Sets an alarm to be triggered at specific time once
alarm_schedule_once_at_date()	Sets an alarm to be triggered after specific delay once
alarm_schedule_with_recurrence_week_flag()	Sets an alarm to be triggered at specific time with recurrent days of the week(can repeat on days of the week)
alarm_schedule_after_delay()	Sets an alarm to be triggered after specific time(Since 3.0, this api does not support exact period and delay for minimizing the wakeups of the device. The system can adjust when the alarm expires.)

If the operation of app_control is APP_CONTROL_OPERATION_DEFAULT, the package information is mandatory to explicitly launch the application. Since 3.0, this api does not support exact period and delay for minimizing the wakeups of the device. The system can adjust when the alarm expires. If you want to trigger an alarm exactly, see

See also:: alarm_schedule_once_after_delay() Since 3.0If app_control is specified with service-application, the application is only allowed to run on which has Background Category. Since 3.0If the appid of app_control is not specified, this api is not allowed. In other words, the explicit app_control is only allowed. Since 4.0, http://tizen.org/privilege/appmanager.launch privilege is additionally required.

Parameters:

[in]	app_control	The destination app_control to perform a specific task when the alarm is triggered
[in]	delay	The amount of time before the first execution (in seconds). Since 3.0, Although this is inexact, the alarm will not fire before this time

When the alarm goes off, Alarm Manager will turn on LCD to prohibit background jobs.

Parameters:

[in]	noti	The notification to be posted when the alarm is triggered
[in]	delay	The amount of time before the first execution (in seconds).
[in]	period	The amount of time between subsequent alarms (in seconds).

If the operation of app_control is APP_CONTROL_OPERATION_DEFAULT, the package information is mandatory to explicitly launch the application. Since 3.0, The app_control only supports UI application with this api. If app_control is not UI application, ALARM_ERROR_NOT_PERMITTED_APP returned. When the alarm is expired, Alarm Manager will turn on LCD to prohibit background jobs. Since 3.0, If the appid of app_control is not specified, this api is not allowed. In other words, the explicit app_control is only allowed. Since 4.0, http://tizen.org/privilege/appmanager.launch privilege is additionally required.

Parameters:

[in]	app_control	The destination app_control to perform specific work when the alarm is triggered
[in]	date	The first active alarm time
[in]	week_flag	The day of the week, week_flag may be a combination of days, like ALARM_WEEK_FLAG_TUESDAY \| ALARM_WEEK_FLAG_FRIDAY
[out]	alarm_id	The alarm ID that uniquely identifies an alarm

Returns:: 0 on success, otherwise a negative error value

Return values:

ALARM_ERROR_NONE	Successful
ALARM_ERROR_INVALID_PARAMETER	Invalid parameter
ALARM_ERROR_INVALID_DATE	Triggered date is invalid
ALARM_ERROR_CONNECTION_FAIL	Failed to connect to an alarm server
ALARM_ERROR_PERMISSION_DENIED	Permission denied
ALARM_ERROR_NOT_PERMITTED_APP	app_control is not permitted. app_control for UI application is only permitted.

int alarm_set_global	(	int	alarm_id,
		bool	global
	)

Sets global flag in the alarm.

Sets global flag to set/unset alarm globally.

Since :: 3.0

Privilege Level:: public

Privilege:: http://tizen.org/privilege/alarm.set

Remarks:: The alarm_id must be id of alarm which will launch global application. The function returns an error (error code ALARM_ERROR_NOT_PERMITTED_APP) if it is not. Note that the application which is launched by global alarm runs in the user session that is logged in currently. It doesn't run in the session for the user who registers the global alarm. So, if the application uses application's private data for each user to handling the app_control for the alarm, it might not show proper data to the user. Therefore, We recommend to contain all the data for the alarm to the app_control handle for the global alarm. Then, the launched application would be able to use the data to show proper alarm UX to the user.

Parameters:

[in]	alarm_id	The alarm ID uniquely identifies an alarm
[in]	global	The global flag to set/unset alarm globally

Returns:: 0 on success, otherwise a negative error value

Return values:

ALARM_ERROR_NONE	Successful
ALARM_ERROR_INVALID_PARAMETER	Invalid parameter
ALARM_ERROR_NOT_PERMITTED_APP	alarm_id is not permitted
ALARM_ERROR_PERMISSION_DENIED	Permission denied

int alarm_update_date	(	int	alarm_id,
		struct tm *	date
	)

Updates the date of the registered alarm.

The date describes the date on which the alarm is set off for the first time. This function can be called for any alarm. If the date was set before, it will be overwritten. If it was not, it will be set.

Since :: 4.0

Privilege Level:: public

Privilege:: http://tizen.org/privilege/alarm.set

Remarks:: This function can be called only for alarms whose app control launches an UI application. If this condition is not met, ALARM_ERROR_NOT_PERMITTED_APP is returned.

Parameters:

[in]	alarm_id	The ID which uniquely identifies the scheduled alarm
[in]	date	The time value of the next alarm event

Returns:: 0 on success, otherwise a negative error value

Return values:

ALARM_ERROR_NONE	Successful
ALARM_ERROR_INVALID_PARAMETER	Invalid parameter
ALARM_ERROR_INVALID_TIME	Triggered time is invalid
ALARM_ERROR_INVALID_DATE	Triggered time is invalid
ALARM_ERROR_CONNECTION_FAIL	Failed to connect to an alarm server
ALARM_ERROR_OUT_OF_MEMORY	Out of memory
ALARM_ERROR_PERMISSION_DENIED	Permission denied
ALARM_ERROR_NOT_PERMITTED_APP	App control does not launch an UI application

int alarm_update_delay	(	int	alarm_id,
		int	delay
	)

Updates the delay of the registered alarm.

The delay is the time (in seconds) before the alarm's first setting off. The delay is an exact value, see alarm_schedule_once_after_delay() for details. This function can be called for any alarm. If the delay was set before, it will be overwritten. If it was not, it will be set.

Since :: 4.0

Privilege Level:: public

Privilege:: http://tizen.org/privilege/alarm.set

Remarks:: This function can be called only for alarms whose app control launches an UI application. If this condition is not met, ALARM_ERROR_NOT_PERMITTED_APP is returned.

Parameters:

[in]	alarm_id	The ID which uniquely identifies the scheduled alarm
[in]	delay	The amount of time before the first execution (in seconds).

Returns:: 0 on success, otherwise a negative error value

int alarm_update_period	(	int	alarm_id,
		int	period
	)

Updates the period of the registered alarm.

The alarm will then go off every period seconds until canceled. This function can be called for any alarm. If the week recurrence flag was set before, it will be removed and the period will be set. If the period was set before, it will be overwritten. If it was not, it will be set. If the period argument is 0 and the period was previously set, the period attribute will be cleared and the alarm will be changed to one-time. If the period argument is 0 and the period was not set, or the week recurrence flag was set, the alarm will be unchanged.
