/** Wrap This scope in other threads **/
int_data = (int*) malloc(sizeof(int));
assert(int_data != NULL);
*int_data = i++;
/*Enqueue*/
 while (lfqueue_enq(&my_queue, int_data) == -1) {
    printf("ENQ Full ?\n");
}

/** Wrap This scope in other threads **/
/*Dequeue*/
while  ( (int_data = lfqueue_deq(&my_queue)) == NULL) {
    printf("DEQ EMPTY ..\n");
}

// printf("%d\n", *(int*) int_data );
free(int_data);
/** End **/

lfqueue_destroy(&my_queue);
