Hi Darren,
we use the code bellow. Just supply your definition for appFileCreator.
The function (proc) is supposed to be in the 1st segment.
Have a nice day.
With best regards,

static int RegisterProcedureNotification( Boolean bRegister, UInt32 notifyType,
SysNotifyProcPtr proc, void *data, Int8 priority)
{
LocalID dbID = FindDatabaseByTypeCreator('appl', appFileCreator) ;
int err = dmErrCantFind ;
if( dbID )
{
DmOpenRef dbRef = DmOpenDBNoOverlay(0, dbID, dmModeReadOnly) ;
if( dbRef )
{
MemHandle h = DmGetResource('code',1) ;
if( h )
{
if( bRegister )
{
MemHandleLock(h) ;
err = DmDatabaseProtect(0, dbID, true) ;
if( err == 0 )
{
err = SysNotifyRegister(0, dbID, notifyType, proc, priority, data) ;
if( err )
DmDatabaseProtect(0, dbID, false) ;
}
if( err )
MemHandleUnlock(h) ;
}
else
{
// Unprotect & Unlock only if we *really* were registered...
err = SysNotifyUnregister(0, dbID, notifyType, priority) ;
if( err == 0 )
{
MemHandleUnlock(h) ;
DmDatabaseProtect(0, dbID, false) ;
}
}
DmReleaseResource(h) ;
}
DmCloseDatabase(dbRef) ;
}
}
return err ;
}

Subject: Notifications, help please
Helloam using notifications
:sysNotifySleepNotifyEventsysNotifyEarlyWakeupEventsysNotifyGotUsersAttentionto
try and detect when the device is woken up using a keypress(user) or an
alarm(system), so that the auto-off timer can be automaticaly set totimes that
will conserve battery power.The notifications for sleep & wake are registered
or unregistered depending ona selection made from a desk accessory, (this means
passing a pointer to
a functionfor the notifs handlers as there is no PilotMain in a desk
accessory).The sysNotifyGotUsersAttention notif is registered in the sleep
notif handler, so that if the device wakes with an alarm sysAutoOff can be set
to a few secs.Anyway, the functions work well for the first alarm but on
following alarms (if repeat alarms are set)it resets.Reading the SDK
documention, there is advice there about locking a function pointer,how is this
done ? Is the pointer that is passed to the sysNotifyRegister a pointer to an
abosulte address inthe storage heap, or is it a pointer that is an offset from
the start of the database
thatspassed?Any help please, many thanks and regardsDarren
