	nvdata function return value 更多...

函数
void	cinv_init (uint32_t flash_addr, uint32_t size)
	initialize the nvdata management information and nvdata region 更多...

cinv_item_ret_t	cinv_item_init (uint32_t id, uint16_t len, void *buf)
	If the nvdata item does not already exist, it is created and initialized with the data passed to the function, if any. This function must be called before calling cinv_item_read() or cinv_item_write(). 更多...

cinv_item_ret_t	cinv_item_read (uint32_t id, uint16_t len, void buf, uint16_t real_len)
	Read data from nvdata. This function can be used to read an entire item or short. Read data is copied into buf. If input length longer than item real length, read item real length data to buf. 更多...

cinv_item_ret_t	cinv_item_write (uint32_t id, uint16_t len, void *buf)
	Write a data item to nvdata. 更多...

cinv_item_ret_t	cinv_item_delete (uint32_t id)
	Delete data item from nvdata. 更多...

cinv_item_ret_t	cinv_register_hotid (uint32_t hot_id)
	register hotid. 更多...
