\class AlarmServer alarmserver.h
\brief The AlarmServer class allows alarms to be scheduled and unscheduled.
Applications can schedule alarms with addAlarm() and can
unschedule alarms with deleteAlarm(). When the time for an alarm
to go off is reached the specified \link qcop.html QCop\endlink
message is sent on the specified channel (optionally with
additional data).
Scheduling an alarm using this class is important (rather just using
a QTimer) since the machine may be asleep and needs to get woken up using
the Linux kernel which implements this at the kernel level to minimize
battery usage while asleep.
\ingroup qtopiaemb
\sa QCopEnvelope
*/
/*!
Schedules an alarm to go off at (or soon after) time \a when. When
the alarm goes off, the \link qcop.html QCop\endlink \a message will
be sent to \a channel, with \a data as a parameter.
If this function is called with exactly the same data as a previous
call the subsequent call is ignored, so there is only ever one alarm
with a given set of parameters.
