+server events</title><prolog><metadata><keywords/></metadata></prolog><conbody>
+<p>The Alarm Server sends notifications to applications when alarm settings
+change; this includes indications when an alarm goes off. A client-side API
+for the alarm server is <xref href="jar:GUID-35228542-8C95-4849-A73F-2B4F082F0C44.jar!/sdk/doc_source/reference/reference-cpp/ALARMSERVER/RASCliSessionClass.html#%3a%3aRASCliSession" format="application/java-archive"><parmname>RASCliSession</parmname></xref>. It is a standard asynchronous service provider, and the client application
+should implement an active object to receive events. </p>
+<p>To be able to use the Alarm Server services, client applications must
+first be connected to the server.</p>
+<codeblock id="GUID-6F5DAB79-F391-4DDD-A85C-EE1C0663E766" xml:space="preserve">User::LeaveIfError( iAlarmServer.Connect() );
+</codeblock>
+<p>In order to receive events, the <parmname>NotifyChange( TRequestStatus
+&amp;aStatus, TAlarmId &amp;aAlarmId</parmname> ) function is called and the
+active object is set active.</p>
+<codeblock id="GUID-6B9CCD08-AE3C-440E-A220-BB3C1766E432" xml:space="preserve">iAlarmServer.NotifyChange( iStatus, iAlarmId ); SetActive();</codeblock>
+<p>Notifications are cancelled by calling the <parmname>NotifyOnChangeCancel()</parmname> function.</p>
+<codeblock id="GUID-CC3EF80B-FF85-4F7C-9665-04C350E5F110" xml:space="preserve"> iAlarmServer.NotifyChangeCancel();</codeblock>
+<p>When alarm settings change, the <parmname>RunL()</parmname> function
+of the active object is called. Alarms in the alarm server database can be
+retrieved using the <parmname>GetAlarmIdListL()</parmname> function, which
+fills an array of alarm IDs.</p>
+<codeblock id="GUID-C583D59A-28BB-46D1-A929-82B748B2CAED" xml:space="preserve">void GetAlarmIdListL( RArray&lt; TAlarmId &gt; &amp;aAlarmIds )</codeblock>
+<p>When using <parmname>RArray</parmname>, remember to call <parmname>Close()</parmname> or <parmname>Reset()</parmname> on
+it when it is not needed anymore. The <parmname>GetAlarmDetails()</parmname> function
+returns the <parmname>TASShdAlarm</parmname> structure for a specific alarm,
+which is identified by the alarm ID. </p>
+<codeblock id="GUID-4870E0F6-42D2-489E-B1AF-2E65D852AEA1" xml:space="preserve">TInt GetAlarmDetails( TAlarmId aAlarmId, TASShdAlarm &amp;aAlarm )</codeblock>
+<p>The <parmname>TASShdAlarm</parmname> structure contains information
+about an alarm, and information is accessed through simple inline functions.
+See the<parmname> ASShdAlarm.h</parmname> header file for further information.</p>
