API

extern int   lfqueue_init(lfqueue_t *lfqueue);
extern int   lfqueue_enq(lfqueue_t *lfqueue, void *value);
extern void* lfqueue_deq(lfqueue_t *lfqueue);
extern void* lfqueue_single_deq(lfqueue_t *lfqueue);
extern void lfqueue_destroy(lfqueue_t *lfqueue);
extern size_t lfqueue_size(lfqueue_t *lfqueue);
extern void lfqueue_sleep(unsigned int milisec);

Example

int* int_data;
lfqueue_t my_queue;

if (lfqueue_init(&my_queue) == -1)
	return -1;

/** 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);

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