Then, based on these actions, the user can determine the mechanism by which the current watchdog keeps alive and take different actions accordingly. for example: ```C int user_wdt_timeout_callback(FAR struct notifier_block *nb, unsigned long action, FAR void *data) { UNUSED(data); UNUSED(nb); switch(action): { case WATCHDOG_KEEPALIVE_BY_ONESHOT: //do something break; case WATCHDOG_KEEPALIVE_BY_TIMER: //do something break; ... } printf("The callback function registered by the user is triggered!\n"); return 0; } ``` -- This is an automated message from the Apache Git Service.
