cinv_item_ret_t	cinv_item_init (uint32_t id, uint16_t len, void *buf)
	如果nvdata 项不存在，会创建和初始化传入的id参数项，在调用cinv_item_read()或cinv_item_write()函数前，必须先调用该函数。更多...

cinv_item_ret_t	cinv_item_read (uint32_t id, uint16_t len, void buf, uint16_t real_len)
	从nvdata里读数据。该函数可以读nvdata项的全部内容或一部分。数据会拷贝到buf数据指针，如果传入的长度大于实际长度，只会将实际长度的数据拷贝到buf数据指针。更多...
