well... it should for such small code :)

but how do i handle this sensibly ?

        res = sfifo_write(sf, &buf, j);
        if(res != j)
        {
                printf("Write failed!\n");

// eeek... no i dont want that...
                sleep(1);
        } else if(res)
                printf("Wrote %d\n", res);
