\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.

/*!
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.

\class Global global.h
\brief The Global class provides application-wide global functions.
The Global functions are grouped as follows:
\tableofcontents
\section1 User Interface
The statusMessage() function provides short-duration messages to the
user. The showInputMethod() function shows the current input method,
and hideInputMethod() hides the input method.
\section1 Document related
The findDocuments() function creates a set of \link doclnk.html
DocLnk\endlink objects in a particular folder.
\section1 Filesystem related
Global provides an applicationFileName() function that returns the
full path of an application-specific file.
The execute() function runs an application.
\section1 Word list related
A list of words relevant to the current locale is maintained by the
system. The list is held in a \link qdawg.html DAWG\endlink
(implemented by the QDawg class). This list is used, for example, by
the pickboard input method.
The global QDawg is returned by fixedDawg(); this cannot be updated.
An updatable copy of the global QDawg is returned by addedDawg().
Applications may have their own word lists stored in \l{QDawg}s
which are returned by dawg(). Use addWords() to add words to the
updateable copy of the global QDawg or to named application
\l{QDawg}s.
\section1 Quoting
The shellQuote() function quotes a string suitable for passing to a
shell. The stringQuote() function backslash escapes '\' and '"'
characters.
\section1 Hardware
- The writeHWClock() function sets the hardware clock to the system
- clock's date and time.
+ The implementation of the writeHWClock() function depends on the AlarmServer
+ implementation. If the AlarmServer is using atd the clock will be synced to
+ hardware. If opie-alarm is used the hardware clock will be synced before
+ suspending the device. opie-alarm is used by iPAQ and Zaurii implementation
