+ * Name: wd_restart
+ *
+ * Description:
+ * This function restarts (reloads) an already-started watchdog timer
+ * with a new delay time, without modifying its existing handler function
+ * or argument.
+ *
+ * It behaves similarly to wd_start(), but is typically used when the
+ * watchdog has already been started and needs to be rearmed before it
+ * expires. The same watchdog function (wdog->func) will be called from
+ * the interrupt level after the specified number of ticks has elapsed.
+ *
+ * Watchdog timers may be started or reloaded from the interrupt level.
+ * Watchdog timers execute in the address environment that was in effect
+ * when wd_restart() is called.
+ * Watchdog timers execute only once.
+ *
+ * Input Parameters:
+ * wdog - Watchdog ID
+ *
+ * Returned Value:
+ * Zero (OK) is returned on success; a negated errno value is returned to
+ * indicate the nature of any failure.
+ *
+ * Assumptions:
+ * The watchdog routine runs in the context of the timer interrupt handler
+ * and is subject to all ISR restrictions.
