Native data structure for FIFO

Hello,

I want to have a data structure which will be accessible across the project and will work as FIFO.

I tried array EINA_ARRAY but it is not FIFO. 

dlog_print(DLOG_ERROR, LOG_TAG, "array count: %d\n",
            eina_array_count(outPutFileNameArray));
    char *filename = (char*) eina_array_pop(outPutFileNameArray);

 

But this pop will give me last element. I want the 0th element. Is there any idea to modify array behaviour to give me required functionality?

 

Regards,

Shraddha

You may try using List instead of Array. According to this link, it works very well as a queue. Please go through the link below:

I am getting error for list for eina_init() when using in service.

You don't need to call eina_init() to use Eina_List. You can simply insert data and retrieve it from the list as below. Please have a look.

Eina_List *list = NULL;
list = eina_list_append(list, "First item");
dlog_print(DLOG_DEBUG, "test", "%s", eina_list_nth(list, 0));
