return -1;
/** Wrap This scope in other threads **/

/*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);
If you are using single thread dequeue/consume. Please use lfqueue_single_deq to get better result
