kStatus kHxNode_UpdateWatchdog	(	kHxNode	node,
		kRestartReason	reason
	)

Updates the watchdog status, optionally resetting the watchdog countdown timer.

If the reason argument is kRESTART_REASON_NONE, this method resets the watchdog countdown timer using the timeout period specified in the most recent call to kHxNode_EnableWatchdog. Otherwise, the reason code is logged (if suported by the underlying platform) and the device is allowed to reboot.

This method is thread safe.
