Routine Description:\r
\r
- This function registers a handler that is to be invoked when the watchdog \r
- timer fires. By default, the EFI_WATCHDOG_TIMER protocol will call the \r
- Runtime Service ResetSystem() when the watchdog timer fires. If a \r
- NotifyFunction is registered, then the NotifyFunction will be called before \r
- the Runtime Service ResetSystem() is called. If NotifyFunction is NULL, then \r
- the watchdog handler is unregistered. If a watchdog handler is registered, \r
- then EFI_SUCCESS is returned. If an attempt is made to register a handler \r
- when a handler is already registered, then EFI_ALREADY_STARTED is returned. \r
- If an attempt is made to uninstall a handler when a handler is not installed, \r
+ This function registers a handler that is to be invoked when the watchdog\r

+ when a handler is already registered, then EFI_ALREADY_STARTED is returned.\r
+ If an attempt is made to uninstall a handler when a handler is not installed,\r
then return EFI_INVALID_PARAMETER.\r

Arguments:\r
NotifyFunction - The function to call when the watchdog timer fires. If this\r
is NULL, then the handler will be unregistered.\r
