Class Watchdog

java.lang.Object

com.cinterion.misc.Watchdog

Deprecated.

Deprecated because in a multi midlet environment it can be confusing when multiple midlets use this single system resourse. Use com.cinterion.misc.Watchdog2 instead.

public class Watchdog
extends Object

The Watchdog class provides the ability to control the CPUs hardware watchdog from application level.
There is a built-in HW watchdog in the system. When this watchdog triggers the module either switches off, reboots, or does nothing. This depends on the watchdog settings (see at^scfg=Userware/Watchdog). The watchdog is disabled when the module starts, the application has to enable it. It is never disabled implicitely. That means that the application has to disable the watchdog again when closing down (i.e. in its destroyApp method. This is especially necessary for OTAP to work correctly.
