C++ (Cpp) sum_val Examples

Example #1

File: rate-submit.c Project: axboe/fio

static void sum_ddir(struct thread_data *dst, struct thread_data *src,
                     enum fio_ddir ddir)
{
    pthread_double_lock(&dst->io_wq.stat_lock, &src->io_wq.stat_lock);

    sum_val(&dst->io_bytes[ddir], &src->io_bytes[ddir]);
    sum_val(&dst->io_blocks[ddir], &src->io_blocks[ddir]);
    sum_val(&dst->this_io_blocks[ddir], &src->this_io_blocks[ddir]);
    sum_val(&dst->this_io_bytes[ddir], &src->this_io_bytes[ddir]);
    sum_val(&dst->bytes_done[ddir], &src->bytes_done[ddir]);

    pthread_double_unlock(&dst->io_wq.stat_lock, &src->io_wq.stat_lock);
}
