You may try lfqueue

It is simple to use, it is circular design lock free

int *ret;

lfqueue_t results;

lfqueue_init(&results);

/** Wrap This scope in multithread testing **/
int_data = (int*) malloc(sizeof(int));
assert(int_data != NULL);
*int_data = i++;
/*Enqueue*/
while (lfqueue_enq(&results, int_data) != 1) ;

/*Dequeue*/
while ( (ret = lfqueue_deq(&results)) == NULL);

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

lfqueue_clear(&results);
