+  Registers a handler that is to be invoked when the watchdog timer fires.
+
+  This function registers a handler that is to be invoked when the watchdog
+  timer fires.  By default, the EFI_WATCHDOG_TIMER protocol will call the
+  Runtime Service ResetSystem() when the watchdog timer fires.  If a
+  NotifyFunction is registered, then the NotifyFunction will be called before
+  the Runtime Service ResetSystem() is called.  If NotifyFunction is NULL, then
+  the watchdog handler is unregistered.  If a watchdog handler is registered,
+  then EFI_SUCCESS is returned.  If an attempt is made to register a handler
+  when a handler is already registered, then EFI_ALREADY_STARTED is returned.
+  If an attempt is made to uninstall a handler when a handler is not installed,
+  then return EFI_INVALID_PARAMETER.
+
+  @param  This                  The EFI_WATCHDOG_TIMER_ARCH_PROTOCOL instance.
+  @param  NotifyFunction        The function to call when the watchdog timer fires.  If this
+                                is NULL, then the handler will be unregistered.
+
+  @retval EFI_SUCCESS           The watchdog timer handler was registered or unregistered.
+  @retval EFI_ALREADY_STARTED   NotifyFunction is not NULL, and a handler is already registered.
+  @retval EFI_INVALID_PARAMETER NotifyFunction is NULL, and a handler was not previously registered.
