C++ (Cpp) sys_slist_init Examples

Example #1

File: queue.c Project: bboozzoo/zephyr

void k_queue_init(struct k_queue *queue)
{
	sys_slist_init(&queue->data_q);
	sys_dlist_init(&queue->wait_q);

	_INIT_OBJ_POLL_EVENT(queue);

	SYS_TRACING_OBJ_INIT(k_queue, queue);
}

Example #2

File: queue.c Project: bboozzoo/zephyr

void k_queue_merge_slist(struct k_queue *queue, sys_slist_t *list)
{
	__ASSERT(!sys_slist_is_empty(list), "list must not be empty");

	/*
	 * note: this works as long as:
	 * - the slist implementation keeps the next pointer as the first
	 *   field of the node object type
	 * - list->tail->next = NULL.
	 */
	k_queue_append_list(queue, list->head, list->tail);
	sys_slist_init(list);
